Received Warning message "Path set to RVM" after updating ruby version using rvm

Question

Recently I tried to update my ruby version due to a warning message (see below).

Now I get the following warning message when I start my iterm2:

Warning: PATH set to RVM ruby but GEM_HOME and/or GEM_PATH not set, see:     https://github.com/wayneeseguin/rvm/issues/3212 

Does anyone know how to resolve this warning? It hasn't really impacted my work but it is a little unsettling.

for your information:
1. I believed I ran rvm get stable to get the latest ruby version.
2. this is the warning message I was initially trying to resolve but it has not been resolved either:

warning: parser/current is loading parser/ruby21, which recognizes warning: 2.1.5-compliant syntax, but you are running 2.1.2. 

I am using 1. Mac OS X 2. iterm2 and 3.oh-my-zsh shell

Answer 1

I had same issue with oh-my-zsh While installing rvm with option --rails, there was this warning:

This solution works for me: Open .zshrc file, and find PATH line

change

export PATH=/path/to/something

into

export PATH="$PATH:/path/to/something"

save it and do source ~/.zshrc, Then it worked.

Answer 2

If you find a line after User configuration in the ~/.zshrc file like this:

#export PATH="/Users/robinwen/.rvm/gems/ruby-1.9.3-p551@robin/bin:/Users/robinwen/.rvm/gems/ruby-1.9.3-p551@global/bin:/Users/robinwen/.rvm/rubies/ruby-1.9.3-p551/bin:/Users/robinwen/.rvm/bin:/usr/local/git/bin:/sw/bin:/usr/local/bin:/usr/local:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin/"

You should comment this line, and add following line:

export PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting

Good luck!
