Today I decided to finally upgrade my Ruby on Rails setup at home. But upon running the rails -v command, I ran into this error:
bash: /opt/local/bin/rails: /opt/local/bin/ruby: bad interpreter: No such file or directory
Turns out for some reason there’s another (non-working) copy of rails in my /opt/local/bin/ directory. To fix the problem, I simply had to remove it (along with rake and other related executables out of there).
On a related note, I also tried upgrading rvm. But while trying to upgrade Ruby to the latest 1.9.3 with it using the rvm install 1.9.3, I kept getting this error:
curl: (7) couldn't connect to host
Finally, what worked was this:
curl -L get.rvm.io | bash -s stable --ruby
And to bind that to rails, similarly, do this:
curl -L get.rvm.io | bash -s stable --rails
That’s it.
Happy hacking.
