Failed to build gem native extension

[Boztown]

Foward: I solved this. Just want to document it for you.

I switched from RVM to RBENV. I tried to run "bundle" on a project and got this:

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

    /Users/ryanbosinger/.rbenv/versions/2.0.0-p353/bin/ruby extconf.rb 
/Users/ryanbosinger/.rbenv/versions/2.0.0-p353/bin/ruby: invalid option -P  (-h will show valid options) (RuntimeError)

It turns out the problem was that my app folder was in a directory called "Local Projects". The space threw it off and I think that's where the -P option was coming from (the start of "Projects").

This is on MacOS 10.9. I'm not sure if it's an rbenv problem, a bundler problem or just a system thing. The directory name wasn't an issue with my RVM set-up though.

Might be an rbenv bug with failing to escape paths with spaces somewhere.

When you ran bundle install, did you install into the project's directory (with --standalone or --path=vendor/bundle), or you did a default bundle install which installs into system gems (for that Ruby version)?

Possible cause: rubygems/rubygems#523

The workaround is to avoid installing gems in paths that have spaces for now.
