Installing the Debugger Gem under Ruby 2.1.1ΒΆ

The debugger-1.6.6 gem needed for use with ruby 2.1.1 is not compatible with gcc-4.5. If you see bundle install failures with the debugger gem, you will need to configure Solano CI workers to use gcc-4.6.


If you change the gcc version that’s used to process your build, you may see failures if your bundler dependencies are not rebuilt. See our guide on Caching Dependencies for more information.

To change the gcc version that’s used, follow these instructions.
