"Warning! PATH is not properly set up" when using RVM with tmux

[srghma]

set -g default-command "$SHELL -l"
set -g default-shell "$SHELL"

didnt work for me, what I do:
start without tmux

$ echo $PATH 
/home/bjorn/.rvm/gems/ruby-2.4.0/bin:/home/bjorn/.rvm/gems/ruby-2.4.0@global/bin:/home/bjorn/.rvm/rubies/ruby-2.4.0/bin:/home/bjorn/.cabal/bin:/usr/local/heroku/bin:/home/bjorn/.node_modules/bin:/home/bjorn/.bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/home/bjorn/.rvm/bin

$ tmux 
$ tmux show-options -g G def
default-command "/bin/zsh -l"
default-shell "/bin/zsh"
$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl
$ zsh
$ echo $PATH 
...all great again

My tmux and others dotfiles at that moment

temporal solution: in zshrc
[[ $TMUX != "" ]] && rvm use default > /dev/null 2>&1

rvm infos

[mpapis]

can you show your zshrc?

[srghma]

Yes, it in my dotfiles, but without this line, its temporal solution as I have written

zshenv

[mpapis]

zshenv file in which you load RVM (source "$HOME/.rvm/scripts/rvm") is the first sourced file in the process of initializing ZSH, you should move this line to zshrc after you finish setting up PATH and source'ing other files.

[srghma]

Ok, that indeed worked, I thought that my nvim will not find rvm after that, but no, thank you very much 🥇

I had a bit of headaches also for this question (post update to Debian Stretch)

In my case, I use zprezto and I solved it with edit .zprofile

# Set the list of directories that Zsh searches for programs.
path=(
  $path:$home/.rvm/bin
  /usr/local/{bin,sbin}
  $path
)
# RVM
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
