Installing Gems without rvm, as root, with explicit version of ruby

Question

I've decided to get rid of rvm, and I'm having trouble compiling a gem with my new version of ruby 1.9.2. The gem requires 1.9.2, I have it, yet says it can't install without, so the error messages makes no sense.

How can I explicitly tell the gem to compile with said version of ruby?

Gem::InstallError: linecache19 requires Ruby version >= 1.9.2.
An error occured while installing linecache19 (0.5.12), and Bundler cannot continue.
Make sure that `gem install linecache19 -v '0.5.12'` succeeds before bundling.
 apps2 ~/projects/sms/apps2/apps2_admin $ ruby -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.8.0]
 apps2 ~/projects/sms/apps2/apps2_admin $ which ruby
/usr/local/bin/ruby

Answer 1

I had the same issue (linecache19 hangs forever/indefinitely) when using rbenv on OS X Lion. I found the solution was to install Ruby with OpenSSL option, like this:

rbenv install 1.9.2-p290 --with-openssl-dir=/usr/local
rbenv rehash
rbenv global 1.9.2-p290

Now, you can run or bundle this and it'll install fine:

gem install ruby-debug19

Hope that helps someone.

Worked for me to get past a bundle failure. Thanks! – Mediatorial

Answer 2

I had a similar issue and traced back the issue and solved it as follows:

The root of the issue is that in the gem installer.rb file the passed required ruby version from linecache19 is 1.9.2 while the Gem.ruby_version is something like 1.9.2.dev.30909, and ("1.9.2" >= "1.9.2.dev.30909") is false.

so first become sure that ruby version is 1.9.2:

ruby -v

then manually use --force to bypass version check:

gem install ruby_core_source
gem install linecache19 --force

if you faced with another error starting with following lines:

checking for vm_core.h... no
*** extconf.rb failed ***

You have to explicitly set the source path to vm_core.h

In my case:

$ which ruby
/Users/Reza/.rvm/rubies/ruby-1.9.2-rc2/bin/ruby
$ echo $rvm_path
/Users/Reza/.rvm/

so to install linecache19 :

gem install ruby_core_source
gem install linecache19 --force -- --with-ruby-include=$rvm_path/src/ruby-1.9.2-rc2/

ruby-debug19 has a similar issue:

gem install ruby-debug19 --force -- --with-ruby-include=$rvm_path/src/ruby-1.9.2-rc2/

That's all!

Answer 3

This is what worked on Ubuntu:

I had the same problems and tried so many options before I came across this: http://beginrescueend.com/packages/openssl/

$ rvm pkg install openssl
$ rvm remove 1.9.2
$ rvm install 1.9.2 --with-openssl-dir=$rvm_path/usr

This resolves the issue with linecache19 rubydebug-19 and openssl:

*** extconf.rb failed ***
custom_require.rb:36:in `require': no such file to load -- openssl (LoadError)

then you can do

gem install ruby-debug19
