Rails Server will not run

Question

Typing

$ rails server 

in terminal on mac yields these two errors that I\'ve tried troubleshooting by uninstalling and installing ruby &am

Answer 1

EDIT: try running gem pristine --all first.

Try uninstalling and reinstalling bundler:

gem uninstall bundler then gem install bundler

Then run bundle install.

This will install all the gems you should have specified in your Gemfile, as well as all the extensions.

E.g Bundle complete! 33 Gemfile dependencies, 103 gems now installed.
