After updating Ubuntu, it no longer loads Ruby or something like that, the error message that returns is:

/usr/bin/env: "ruby2.1": File or directory not found

Every time I have to start the application

ruby-on-rails linux ruby ubuntu updating

  • tried to reinstall Ruby, or check the version of Ruby? may be q on system update installed version 2.3

  • What the system returns when you type $ ruby ?

  • I think the best thing to do is to open the terminal and make a sudo apt-get --purge autoremove ruby or a sudo apt-get --purge remove ruby the only difference is that the autoremove also uninstall dependencies while the remove no. correct me if I’m wrong.

Make sure that Ruby version 2.1 is installed using dpkg -l ruby2.1 (must have a ii on the left) or even if you are in PATH with which ruby2.1 (shall return /usr/bin/ruby2.1). If both tests are positive, then the application you’re using that you might be looking for Ruby in another corner, maybe it’s using rbenv to select the interpreter version.

Apparently I was able to solve the problem by clicking on Edit->Profile Preferences->Command -> Run command as Session shell -> Restart terminal
