I have a rails 3 app that was made with 2.0.0-p0 ruby.
Now i would like to update just the ruby to 2.2.2
I changed already the local and global ruby on rbenv to 2.2.2.
There is a way or i have to keep using the 2.0.0-p0 on this app?
You have switched to another version of Ruby and you are probably using a different gemset (probably an empty one). Try running:
bundle install
Note that after switching to a newer version of Ruby, some of your old code might not be compatible, i.e. need debugging.
Hope this help!
