Installing Nokogiri on OSX 10.10 Yosemite

I recently upgrade to the 10.10 Yosemite beta, but I'm having trouble getting Nokogiri installed. I'm using RVM and Ruby 1.9.3. I've also followed the steps here and tried following the instructions on Nokogiri's homepage.

I've installed libxml2 (2.9.1) and libxslt (1.1.28) via homebrew, and have tried using the command line tools from both my Xcode 5 install and Xcode 6 beta.

gem install nokogiri -v '1.5.5'
Building native extensions.  This could take a while...
ERROR:  Error installing nokogiri:

Anyone have an idea on how to fix these install errors?

EDIT 6/10/14: After trying for a couple days to get Nokogiri installed on OSX 10.10, I ended up abandoning the task and restored 10.9 on my machine. Several libraries and bundles need to be updated in order to work in the 10.10 environment.

I have the development tools installed. I have Xcode 6 and I've separately downloaded and installed the command line tools for 10.10. – Hodeida 6/6, 2014 at 23:13

Hope this might help: #24092369 – Carnivorous 10/6, 2014 at 22:2

I managed to solve this same problem upgrading to ruby 2.1.2 (with rvm). After a nightmare session of gems, brews and whatnot :/ – Zindman 4/10, 2014 at 10:47

I have a very similar problem: OS X 10.10 (Yosemite), RVM 1.26.3, Ruby 1.9.3 (ruby-1.9.3-p551), Nokogiri 1.6.1. I've tried various ideas from SO and elsewhere, but no luck so far. – Hitoshi 9/12, 2014 at 22:30

I managed to install Nokogiri under Yosemite (OS X 10.10 Preview).

Step 1: Install Brew

Skip this if brew was installed.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Step 2: Install brew libs

brew tap homebrew/dupes
brew install libxml2 libxslt
brew install libiconv

Step 3: Download and install Apple Commandline Tools for 10.10

It's important that you need to restart after installation.

Link: command_line_tools_for_osx_10_10_june_2014.dmg

After restarted, you can check installation in Terminal:

> xcode-select --install
-> xcode-select: error: command line tools are already installed, use "Software Update" to install updates

This error means you have commandline tool installed correctly.

Installing Nokogiri

Try using n previous version 1.6.1 in your Gemfile, version 1.6.2.1 has issues currently with "10.10 Preview". It only works with my rbenv Ruby 2.0.0p247, failed to install on 2.1.1. You can give your existing Ruby versions a couple of tries.

gem install nokogiri  -v '1.6.1' -- --with-iconv-dir=/usr/local/Cellar/libiconv/1.14/

Carnivorous answered 10/6, 2014 at 22:1 Comment(15)

I uninstalled and reinstalled Homebrew as I was getting 'bad interpreter' then I was able to run the brew commands. – Businesslike 11/6, 2014 at 14:56

brew install libiconv - this gave me Error: Permission denied - /usr/local/Cellar/libiconv/1.14 – Molybdenous 19/6, 2014 at 14:28

also code-select --install is giving me this - Error: Permission denied - /usr/local/Cellar/libiconv/1.14 and your above dmg link no longer work – Molybdenous 19/6, 2014 at 14:32

apple just released an update 1.0 to 10.10, try the upgrade see if that fixes the issue. you need 'sudo' when seeing those permission errors.. – Carnivorous 19/6, 2014 at 16:0

If you're installing nokogiri via bundler, use the following before installing: bundle config build.nokogiri --with-iconv-dir=/usr/local/Cellar/libiconv/1.14/ – Aerialist 9/9, 2014 at 1:0

I also faced the same problem today and problem was same some missing lib libconv.... You just need to install the developer tools (run xcode-select --install in command line) and voila after that just reuse bundle install/or gem install whatever you were using earlier. For me homebrew was working fine. – Foreworn 18/10, 2014 at 13:40

for 1.6.1 I am getting the message couldn't understand kern.osversion 14.0.0'` in mkmf.log located in ~/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/extensions/x86_64-darwin-13/2.1.0-static/nokogiri-1.6.1/ the installation of 1.6.3.1 works nicely but not 1.6.1. I use the gem backup which depends on 1.6.1 – Millikan 20/10, 2014 at 20:0

Your point about xcode-select is interesting and important: having xcode installed is not enough; it will give access to clang but apparently not the right libraries. After the download from the prompt it installed cleanly for me without – Verde 21/10, 2014 at 21:49

The instructions above contain an old URL for installing Brew, the new one is ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" – Univalve 22/10, 2014 at 14:39

I found that on a fresh Yosemite 10.10 install with ruby-2.0.0-p594 installed via rvm that I had to first symlink gcc-4.2 Then I installed the brew dependencies: brew install libxml2 libxslt and finally nokogiri with gem install nokogiri -- --use-system-libraries – Badoglio 30/10, 2014 at 11:32

The link for installing the Apple Command Line Tools for 10.10 has restricted access. Would anyone with access be willing to post the instructions? – Witness 27/3, 2015 at 23:48

This helped me, but I also needed to do this: sudo xcodebuild -license. – Nita 16/4, 2015 at 1:40

I need to use

gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2

it also worked on 10.9 (after changing the sdk version). – Uncrowned 18/6, 2015 at 3:30

It took me couple of hours to make it work & with your solution works! Thanks! – Pal 15/9, 2015 at 21:46

For El Capitan, the above gets updated to the following:

sudo gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2/

libxml2 - 1.6.6.2 in Yosemite:

sudo env ARCHFLAGS="-arch x86_64" gem install nokogiri -- --use-system-libraries  -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.2/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.2/lib --with-xslt-lib=/usr/local/lib --with-xslt-include=/usr/local/include

Herron answered 3/2, 2015 at 12:19 Comment(6)

This worked for me, but I had to add -v '1.6.1' to it:

sudo env ARCHFLAGS="-arch x86_64" gem install nokogiri -v '1.6.1' -- --use-system-libraries  -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.2/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.2/lib --with-xslt-lib=/usr/local/lib --with-xslt-include=/usr/local/include

I could install the latest nokogiri gem, but running bundle install didn't work unless I used the specific version it asked for. (Maybe this is a project config.? Don't know enough about Ruby to know, I just know this is what finally worked for me.) – Archaeozoic 6/3, 2015 at 20:59

Thank you I use these options also for installing fastlane ! – Constipate 20/3, 2015 at 10:0

@DavidYeiser You can pass Nokogiri version like this 'nokogiri:1.6.1' – Herron 21/4, 2015 at 6:24

I could use it without sudo for ruby-2.1.0 – Laddy 24/8, 2015 at 10:23

@DavidYeiser thank you, after many attempts your solution was the only one that worked for me in Yosemite! – Discriminator 11/11, 2015 at 21:33

I got (Errno::EPERM) Operation not permitted but with a different bin dir https://mcmap.net/q/180930/-cannot-install-cocoa-pods-after-uninstalling-results-in-error the answer from @Herron worked a treat (getting default version 1.6.8 as of this date):

sudo env ARCHFLAGS="-arch x86_64" gem install nokogiri -n /usr/local/bin -- --use-system-libraries  -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.2/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.2/lib --with-xslt-lib=/usr/local/lib --with-xslt-include=/usr/local/include

For Mac OS El Capitan:

I had the same problem with MacPorts ruby2.1:

can not gem install nokogiri on osx10.10 with macports ruby2.1

The install starts, the cpu goes to 50% on a single core at 100%, then CPU drops to near zero, but iostat tps goes through the wall.

This helped:

# port install libiconv libxslt libxml2

# gem install nokogiri -- --use-system-libraries --with-iconv-dir=/opt/local --with-xml2-dir=/opt/local --with-xslt-dir=/opt/local

For anyone else that hasn't been able to get this to work on El Capitan, what finally worked for me was:

sudo gem install nokogiri -- --use-system-libraries --with-xslt-dir=/usr/local/opt/libxslt --with-iconv-dir=/usr/local/opt/libiconv --with-xml2-dir=/usr/local/opt/libxml2 --with-xml2-config=/usr/local/opt/libxml2/bin/xml2-config --with-xml2-include=/usr/local/opt/libxml2/include/libxml2 --with-xslt-config=/usr/local/opt/libxslt/bin/xslt-config

I don't have macports installed, and my system is a weird hodge-podge. Forcing specific installations for each dependency is the only way that I can get Nokogiri to compile. Super annoying, but at least it works.

The instructions from the Nokogiri website worked for me on both OSX 10.9 and 10.10.

brew unlink gcc-4.2      # you might not need this step
gem uninstall nokogiri
xcode-select --install
gem install nokogiri

(full answer here https://gist.github.com/chrisb/4d6a09c6cc1ca2e1b14e)

It looks like Homebrew somehow depends on Ruby being in Versions/1.8 (though even Mavericks ships with 2.0). Until Homebrew addresses this, we'll symlink our system version of Ruby to the one Homebrew looks for.

Create the folder:

sudo mkdir -p /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin

Then symlink the binary:

sudo ln -s /usr/bin/ruby /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

$ gem install nokogiri -v 1.6.8 -- --use-system-libraries --with-xml2-include=/usr/local/opt/libxml2

on environment like this:

The only thing that worked for me was to upgrade the compiler from apple-gcc42 to gcc48:

brew uninstall apple-gcc42
brew install gcc48 # this might take an hour or so
rvm implode
\curl -sSL https://get.rvm.io | bash -s stable # reinstall RVM
rvm install ruby-1.9.3-p551
bundle update libv8 # 3.16.14.3 doesn't work but 3.16.14.7 does
bundle

If you're using OS X 10.10 and MacPorts you have to install pkgconfig as well:

sudo port install pkgconfig libxml2 libxslt libiconv

Also if you want to use MacPorts libraries automagically without adding configure options you'll need to add this to your .profile or .bashrc:

export PATH=/opt/local/bin:/opt/local/sbin:$PATH
export MANPATH=/opt/local/share/man:$MANPATH
export LDFLAGS="-L/opt/local/lib"
export CPPFLAGS="-I/opt/local/include"

And also you may want to add this to tell Nokogiri to always use your system libraries:

export NOKOGIRI_USE_SYSTEM_LIBRARIES=Y

Restart terminal after adding all these exports.

Using this configuration you can install Nokogiri using:

gem install nokogiri

This one worked fine for me with OS X 10.9. I had to switch before to sudo xcode-select -s /Library/Developer/CommandLineTools though – Leggett 7/10, 2016 at 12:26

I got the same error message on OS X Yosemite version 10.10.5

I had recently done various OS updates and it turned out I only needed to accept the new xcode license agreement using the following command:

sudo xcodebuild -license

I think the issue is related to the system Ruby not being found or multiple Rubies are installed.

Do you use RVM to manage rubies?
What is the output of ruby -v?

Those should be the starting point to finding a solution.

The bad interpreter error is related to a problem with the Ruby installation.

Ideally, you should start with the system Ruby, the one that ships with Xcode. So, you would uninstall Xcode completely using:

http://osxdaily.com/2012/02/20/uninstall-xcode/

Uninstall brew, rvm and reinstall them.

Moo answered 13/6, 2014 at 18:44 Comment(1)

Mac OS has shipped with Ruby pre-installed for a long time. It isn't installed by Xcode, so "start with the system Ruby, the one that ships with Xcode" is just confusing. Uninstalling Xcode isn't going to remove the system Ruby, only removing the system would do that and you don't want to go there. – Inextirpable 23/6, 2015 at 3:17

For me switching to Xcode 5 rather than using Xcode 6's CLI tool:

In my case, the error message was written below and the accordingly solution as well.

Error message:

...
libxml2 is missing.  Please locate mkmf.log to investigate how it is failing.
...

Solution:

gem install nokogiri -- --use-system-libraries --with-libxml2lib=/usr/local/opt/libxml2/lib/libxml2.a

I directly gave it the path of the library of libxml2.a

gem install nokogiri

Try updating gcc version:

Kersey answered 10/6, 2014 at 10:12 Comment(3)

I gave that a shot, and it still doesn't install. I believe its an issue installing the libv8, and I've opened an issue here: github.com/cowboyd/libv8/issues/123 – Hodeida 10/6, 2014 at 15:5

@Hodeida update gcc version and then try. see links in updated answer. – Kersey 10/6, 2014 at 16:47

I've tried updating GCC, as well as went through all the posts you mentioned here. Nothing that worked for previous OSX versions seems to work for 10.10 – Hodeida 10/6, 2014 at 20:55

Step 1: Install Brew

Step 2: Install brew libs

Step 3: Download and install Apple Commandline Tools for 10.10
