Can anyone get the rc option to work with RVM?

[istrasci]

My GUI git client (GitKraken) cannot find the lefthook executable because it cannot load RVM. After days of searching for a solution, I came across the rc option of lefthook. I created a .lefthookrc file, and try to load RVM within it, but it is still not working.

Has anyone had success with loading RVM in the rc file? Here is what I have (with some debug output). Note that committing from the command line works just fine because RVM and the env variables get loaded correctly. Default shell is ZSH.

echo "~~~~~~~~~~~~~~~~~~~ .LEFTHOOKRC ~~~~~~~~~~~~~~~~~~~"

echo "-- which ruby: $(which ruby)"
echo "-- which lefthook: $(which lefthook)"

export PATH="$PATH:$HOME/.rvm/bin"

# Load RVM into a shell session *as a function*
[ -s "$HOME/.rvm/scripts/rvm" ] && . "$HOME/.rvm/scripts/rvm"
type rvm | head -1

echo "-- which ruby: $(which ruby)"
echo "-- which lefthook: $(which lefthook)"
