RVM PATH is not properly set up - ruby

Question

I've recently run into the following error from rvm when trying to upgrade my ruby version.
Warning! PATH is not properly set up, '/home/sam/.rvm/gems/ruby-2.2.1/bin' is not at first place,
My echo $PATH is as follows:
/usr/local/heroku/bin:/home/sam/.rvm/gems/ruby-2.2.1/bin:/home/sam/.rvm/gems/ruby-2.2.1#global/bin:/home/sam/.rvm/rubies/ruby-2.2.1/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/sam/.rvm/bin:/home/sam/.rvm/bin:/home/sam/.rvm/bin:/home/sam/.rvm/bin
My .bashrc has the following lines in it
export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting
### Added by the Heroku Toolbelt
export PATH="/usr/local/heroku/bin:$PATH"
And .bash_profile has:
[[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
And my rvm info is as follows
Warning! PATH is not properly set up, '/home/sam/.rvm/gems/ruby-2.2.1/bin' is not at first place,
usually this is caused by shell initialization files - check them for 'PATH=...' entries,
it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
to fix temporarily in this shell session run: 'rvm use ruby-2.2.1'.

I found a solution to a similar problem here. But apparently not close enough (the proposed solution had no effect).
Anyway if anyone has any ideas, I'd appreciate it. I'm a little clueless on the ins and outs of rvm so I'm a bit in the dark here. Thanks in advance
Edit:
I tried reversing the order of the two rvm lines in my .bashrc but this did not help the error, nor did it change the order shown by echo $PATH.

Answer 1

Your PATH does not start with /home/sam/.rvm/gems/ruby-2.2.1/bin because you have a line prepending the Heroku toolbelt path.
You can check this is true by running this in your terminal:
PATH=/home/sam/.rvm/gems/ruby-2.2.1/bin:$PATH rvm info
It shouldn't complain.
The problem comes from Heroku toolbelt modifiying your env in ways rvm doesn't care for.
As per this post, the fix is to change your .bashrc like so:
### Added by the Heroku Toolbelt
export PATH="/usr/local/heroku/bin:$PATH"
export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting
# Load RVM into a shell session *as a function*
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
You can remove the rvm line from .bash_profile

To solve it I just changed in my .profile file:
PATH="$HOME/bin:$HOME/.local/bin:$PATH"
to
PATH="$PATH:$HOME/bin:$HOME/.local/bin"
