RVM won't work over SSH (as a function)

问题:

I just installed RVM on a Debian 6 server, without having any problem in the beginning. However after everything is set up, I can't run RVM in the terminal. The message I get when I type rvm use is:

RVM is not a function, selecting rubies with 'rvm use ...' will not work.  You need to change your terminal emulator preferences to allow login shell. Sometimes it is required to use `/bin/bash --login` as the command. Please visit https://rvm.io/integration/gnome-terminal/ for a example.

rvm installation not working: "RVM is not a function"" they managed to solve the problem but not for SSH.

run:

rvm get stable --auto-dotfiles

it will remove and re-add rvm lines from shell initialization files

for ssh connections to work you need to set your shell as bash(preferred) or zsh, you can check your current shell with:

getent passwd $USER | awk -F: '{print $NF}'

and if it is not bash/zsh change it with:

chsh $USER --shell `which bash`

You need to source /etc/profile.d/rvm.sh first. Add the following line to your .bashrc (or type it at the prompt) :

source /etc/profile.d/rvm.sh

Alternatively, if you need a function, the following script works for me :

#!/bin/sh  #RVM stuff # Load RVM into a shell session *as a function* if [[ -s "$HOME/.rvm/scripts/rvm" ]] ; then    # First try to load from a user install   source "$HOME/.rvm/scripts/rvm"  elif [[ -s "/usr/local/rvm/scripts/rvm" ]] ; then    # Then try to load from a root install   source "/usr/local/rvm/scripts/rvm"  else    printf "ERROR: An RVM installation was not found.\n"  fi

When SSH launches bash, bash doesn't source .bashrc, in default builds (there is a compile-time flag, SSH_SOURCE_BASHRC, that forces it to). Try using something like this in your SSH command line:

ssh user@host "bash -i"

See ssh command execution doesn't consider .bashrc | .bash_login | .ssh/rc?.
