CocoaPods not working in macOS High Sierra

After upgrading to macOS High Sierra CocoaPods is not working. While it is tempting to move away from CocoaPods, it's unfortunately not in scope right now. The error message is below.

zsh: /Users/****/.gems/bin/pod: bad interpreter: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin: no such file or directory

I realize that the error stems from Ruby being upgraded but what is the easies fix? Trying to make CocoaPods use the new ruby version yields other errors.

Edit: For now i installed Ruby 2.0 with rvm install 2.0.0 and rvm use 2.0.0 and then reinstalled CocoaPods sudo gem install cocoapods. Seems to be working now.

Did you update the Command Line Tools? – Viscount 6/6, 2017 at 17:30

@Viscount Yes, sudo xcode-select -s /Applications/Xcode-beta.app and sudo xcode-select --install and followed the GUI from there. – Unwished 6/6, 2017 at 18:22

I was thinking of the ones here: developer.apple.com/download/more I often find external tools don't work until I install those. – Viscount 6/6, 2017 at 19:4

According to https://github.com/CocoaPods/CocoaPods/issues/6778 reinstalling CocoaPods should solve this issue:

sudo gem install cocoapods

A simple "brew reinstall cocoapods" worked (as it runs this exact command for you). Thank you for pointing that out. – Maag 11/7, 2017 at 10:11

Although this works, it should definitely be a CocoaPods issue, since it is unable to locate the updated Ruby version. Probably reinstalling it just checks for the installation again and therefore "fixes" it. – Villon 4/9, 2017 at 17:50

gem install cocoapods - throws no implicit conversion of nil to string error but "brew reinstall cocoapods" did the job. thanks @Maag – Hazzard 26/9, 2017 at 11:14

gem install -n /usr/local/bin cocoapods helps me – Lepanto 3/12, 2017 at 8:24

Since i updated to 10.13 OS, Provided sudo gem install cocoapods again & it's worked. – Skyway 11/1, 2018 at 10:33

I hit this on Mojave on omitted sudo, so just gem install cocoapods and it worked, thanks – Drawstring 8/1, 2019 at 4:28

Works for macOS Catalina (v10.15), as well. – Batten 9/10, 2019 at 15:15

Works for macOS Catalina too. – Lanlana 30/10, 2019 at 16:56

After upgrading to macOS High Sierra, get it fixed with following commands:

sudo gem update --system
sudo gem install -n /usr/local/bin cocoapods

once it will be finished then write below command:

pod install

This solution has worked for me...!!!

I got "ERROR: While executing gem ... (Errno::EPERM) Operation not permitted @ rb_sysopen - /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/gem" when running the first command, but running the second still made "pod install" work. Thanks. – Carliecarlile 19/11, 2017 at 23:54

Despite the "warning", I'm going to say thanks here anyway. This was the only thing that worked for me. Simply reinstalling cocoapods (several times) made no difference until I did both of these steps. So - thanks! – Reavis 20/11, 2017 at 14:22

I had to run the ruby update through the following command: sudo gem update -n /usr/local/bin --system – Macao 3/12, 2017 at 3:30

Worked for me (cocoapods 1.5.3). – Twibill 7/7, 2018 at 10:21

After literally trying hundreds of other proposed solutions and spending hours and hours this one finally worked. I can now safely say I love you just as much as I hate the Apple/Mac dev environment! Thanks. – Amir 21/5, 2021 at 9:40

I got this error while installing the CocoaPods

ERROR:  While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/bin directory.

And I used this statement. It worked!

sudo gem install cocoapods -n /usr/local/bin

This solved my problem:

$ brew install ruby
$ gem install -n /usr/local/bin cocoapods

Please give a short explanation of what the posted code does so people that are new to this technology have a change to understand and re-use your answer :-) – Costanzo 23/10, 2017 at 13:5

People new to cocoapods should know how to read like the others. – Washwoman 23/10, 2017 at 13:7

@MathieuVIALES, the "brew install ruby" assumes you already have Homebrew packager (brew.sh). That command then installs (or probably technically re-installs ruby since you actually need ruby to install Homebrew itself). The next line "gem install -n /usr/local/bin cocoapods" reinstalls the CocoaPod program (more at cocoapods.org). – Kila 1/3, 2019 at 19:21

Simply run below command:

sudo gem install -n /usr/local/bin cocoapods

This works for me:

brew link --overwrite cocoapods

So I ran into this problem as well after having updated to High Sierra, and it seems like there's been some changes to a location of file that the ruby framework was accessing.

You can solve it using the,

sudo gem install cocoapods

and then update pods as well with for safe measures

pod repo update

and finally

pod install

to make the pod file work again.

Hope this helps out :)

Try using

For me, I had to:

gem uninstall cocoapods
which pod

It still showed it in the path, so I deleted that. Made sure it still didn't show up.

Then

gem install cocoapods

Bulgaria answered 16/10, 2017 at 22:37 Comment(1)

Finally ! Deleting old pod executable before installing cocoapods worked for me – Lon 8/3, 2018 at 19:2

MacOS High Sierra uses ruby 2.3 by default. After upgrading to it, some old ruby gems might not function properly. This problem occurs to me when I ran the bundle command (bundler is a ruby gem; it has a utility called bundle).

So, to clarify, any old ruby gems (cocoapods, bundler, etc) that are trying to access ruby 2.0 will fail.

The solution is to reinstall those old gems in a directory where you have permissions to write.

For cocoapods,

sudo gem install cocoapods -n /usr/local/bin

will do the trick.

You can optionally upgrade your gem system if you like before the install:

sudo gem update --system

This may prompt to you that the upgrading has failed. But actually, if you type:

gem --version

You can see that the upgrading has been successful.

For bundler or other gems, try to do the same:

sudo gem install gem-to-install(for example, bundler) -n /usr/local/bin

About the -n option. Don't miss that. You can check the gem documentation if you want.

So, the solution is all about reinstalling the old gem to a proper directory.

I also encountered this error after installing High Sierra.

ERROR:  While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/bin directory.

I used the following statement identified by Danh Huynh (see above) and It worked!

sudo gem install cocoapods -n /usr/local/bin

Sudo-less .zhs-friendly solution

Modern macOS discourages using sudo and shifts from bash to zsh, so this answer may be useful if you are not going to fight with the fashion.

Insure that .zshenv exists by touch ~/.zshenv command. Configure the RubyGems environment by adding following lines:
```
export GEM_HOME=$HOME/.gem
export PATH=$GEM_HOME/bin:$PATH
```
Don't forget to relaunch Terminal.
Run gem install cocoapods.

While I'm doing the same I got another error saying that

ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.

Then I did this and worked fine.

sudo gem uninstall cocoapods

sudo gem install cocoapods

This is a common problem when upgraded to Mac OSX High Sierra.

Fix is simply installing Cocoapods (again):

sudo gem install cocoapods

I faced this issue also but fixed it in less dramatical way as various re-installation / updating. Just updated PATH environment variable to point out my existing (2.6.0) ruby version.

I had the same issue after upgrading to Catalina.

I updated ruby install by first installing brew and ruby using these directions. https://gorails.com/setup/osx/10.15-catalina (but only ruby, not rails, etc.)
Then I reinstalled cocoapods using the instructions above.

sudo gem install cocoapods

Then after all that I still received the error above. Then I typed 'zsh' to spawn a new shell and pull in configuration settings in the ~/.zshrc file. After this 'pod update' command worked again.

If cannot install new version cocoapods, example below:
1. Please remove Command line tools
sudo rm -rf /Library/Developer/CommandLineTools
2. Install new Command line tools version
sudo xcode-select --install
3. after installing run below command
open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
