安装Git和Heroku后出现本机扩展错误

Question

I've been searching for a solution since yesterday and everything I've tried leads to a dead end.

New to RoR and walking through tutorials. Everything was working fine, until I started setting up GIT and Heroku. I had to install jruby_windows and heroku-toolbelt, and I believe this botched things up.

Now when I run bundle install I receive the following output errors

An error occurred while installing byebug (9.0.5), and Bundler cannot continue.
Make sure that `gem install byebug -v '9.0.5'` succeeds before bundling.

Answer 1

This probably isnt an official fix. I gave up on trying different things, so I ended up reinstalling by using the railsinstaller. After setting things up again I am able to bundle install with no errors.
