RubyMine2018.2 Warning: PATH set to RVM ruby but GEM_HOME and/or GEM_PATH not set


Each time I run a server, a spec, a custom run configuration, or when IDE runs bundle installs, indexes rake tasks, etc. I get this error. All things seem to work fine though it's very annoying as it clogs the output of commands and RubyMine events log.

Here's an example:

bash -c "/Users/[user]/.rvm/bin/rvm ruby-2.3.1 do /Users/[user]/.rvm/rubies/ruby-2.3.1/bin/ruby /Users/[user]/Projects/idebugs/1.rb"

Warning: PATH set to RVM ruby but GEM_HOME and/or GEM_PATH not set, see:

Warning! PATH is not properly set up, $GEM_HOME is not set.
Usually this is caused by shell initialization files. Search for PATH=... entries.
You can also re-add RVM to your profile by running: rvm get stable --auto-dotfiles
To fix it temporarily in this shell session run: rvm use ruby-2.3.1
To ignore this error add rvm_silence_path_mismatch_check_flag=1 to your ~/.rvmrc file.

Although both variables are present in the environment (the script from above outputs the ENV):

{ ...,

The error did not occur prior to 2018.2 version.

RVM is properly configured and no error happens when ruby is used manually from the terminal.

I use zsh. I tried to configure bash for RVM as well. I switched to bash, confirmed that RVM works. When I manually run the line:

bash -c "/Users/[user]/.rvm/bin/rvm ruby-2.3.1 do /Users/[user]/.rvm/rubies/ruby-2.3.1/bin/ruby /Users/[user]/Projects/idebugs/1.rb"

from the terminal (from within both bash and zsh) I don't see the error. However RubyMine still has it (tried Restart, Clean Caches, Reboot).

I am running into the exact same issue.


Same here, no hint worked for that issue. What's wrong with the installation?


Rolled back to 2018.1.4 and no error of this kind.

But it is starting with another command as with 2018.2.1 - without "bash -c" at the beginning.


I'm getting this same warning too and didn't get it with previous versions


All the devs in my office have exact same error issue after install last updates from RubMine ( OSX 10.13.6, Rubymine, 2018.2.1 )


Same here, just upgraded to 2018.2 and got the GEM_HOME not found error. I have decided not to modify ANY of my shell scripts, I am a paying customer and this is a major inconvenience, you folks at JetBrains should fix this ASAP. Thanks.


According to, this bug is resolved from 2018.2.3.


I am also running into the exact same issue.


I'm running into the exact same issue and it was not fixed by 2018.2.3 EAP


I am now on 2018.2.3 (not EAP) and I re-confirm that it has been fixed. For me at least, @Almog1232.


I had the same issue and had to downgrade to version 2017.3.4 in order for this to go away.


Yup, it is still broken in the latest EAP version. Rubymine not so usable for any of the nice integrations like rubocop and bundler....
I just use command line..
