For some reason everytime I reboot my computer I have to redo a lot of Ruby on Rails setup. I have to redo the “bundle install” to install all of the gems in my Gemfile, and then I have to reinstall rails with “gem install rails” even though I installed rails through RVM. I have never had this issue on another computer with other setups so I’m not sure what is going wrong.
Below is some terminal output that will hopefully help someone debug what is going wrong.
$ rails
Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your “rails” command.
$ rvm -v

$ gem which (this doesnt returns anything oddly)
After I gem install rails:
$ rails -v
Rails 3.2.1
I am guessing this is something wrong with my gem setup but I don’t know enough to know where to dig. If you need any more information to help I can provide it and thank you for anyone who has the time to help.
If you’re using Rails 3.2.1 with RVM, you usually do not need to run ‘gem install’ manually.
My guess is, you’ve installed ruby interpreter via RVM (or possibly, you haven’t installed ruby in RVM), or you haven’t configured RVM to select the default ruby interpreter.
You can configure default ruby by (if you’re using 1.9.3-p0):
Then, the 1.9.3-p0 ruby will in effect after logging in to the shell. You can check which ruby interpreter is in use, by:
If you correctly configured, it should be print like:
In the post bundler-age rails app, you just need to run bundler to install required gems (onto the current gemset in RVM). If you don’t create gemset, global gemset will be used. Run:
will install all gems you need.
Now, since RVM automatically select 1.9.3-p0 with gemset named ‘global’, you don’t need to re-install after boot (as I do).
You can optionally create gemset for the rails app and configure per-directory basis. To configure default gemset/ruby interpreter per application, check the RVM site.
