An error occurred while installing debugger-linecache (1.1.1), and Bundler cannot continue

Question

Any idea how to fix this?

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

/home/durrantm/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb

Solution 1

I had this issue after updating to a newer patch version of ruby. Unfortunately the header files gem "debugger-ruby_core_source" was locked in to an earlier version in the Gemfile.lock so it didn't have the required header files.

All you need to do is update that gem by doing:

bundle update debugger-ruby_core_source

You should be able to bundle install afterwards.

If you aren't using bundler then just install the latest version before trying to install debugger:

gem install debugger-ruby_core_source

Solution 2

Another option is to switch to using ruby p125, e.g.

rvm install 1.9.3-p125
rvm use 1.9.3-p125 --default

I had ruby 1.9.3-p194 and apparently that doesn't have the debug/linecache I need.

Solution 3

open terminal, go to project directory and remove Gemfile.lock using

 rm Gemfile.lock

to remove Gemfile.lock and run

bundle install 

which will create new Gemfile.lock so its easy to do it :)

worked for me.

tyvm dude... wasted like 30mins running in circles til I found your answer

This was a quick hack that I'd no longer recommend as you want to be able to keep moving ruby and rails version forward. Using the above fix by Luke is preferred.

You can do "bundle update" instead of removing the Gemfile.lock - this is effectively doing the same thing.

Same error for me, even after installing debugger-ruby_core_source gem install debugger-ruby_core_source-1.3.5.gem Successfully installed debugger-ruby_core_source-1.3.5 1 gem installed C:\RubyGems\lib\debugGems>gem install ruby-debug-base19x-0.11.29.gem Temporarily enhancing PATH to include DevKit...

@Arpit this fix is for the gem 'debugger' github - not sure it works with windows but you could give it a try....

[Arpit]

Yeah.. already installed the debugger gem. Now, the question is - How to tell this to RubyMine? (it's still searching for ruby-debug-base19x)
