Question

Trying to get a new rails app up and I can’t start the server without bundle installing. I get this error. I tried other stacks with no avail. Thanks in advance for any guidance!

Gem files will remain installed in /Users/jahrichie/.bundler/tmp/2264/gems/debugger-linecache-1.1.1 for inspection.

An error occured while installing debugger-linecache (1.1.1), and Bundler cannot continue.
Make sure that `gem install debugger-linecache -v '1.1.1'` succeeds before bundling.

Answer 1

it looks like you have missed to use a ruby or install bundler in the used ruby and bundler was installed in system ruby (but was rather not the case), try:

rvm use 1.9.3 --install

It will make sure you use a ruby and that it is installed.
