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.

Answer 1

Your console is not running as a login shell and hence have no access to rvm function. If you are running Ubuntu, you can:

1. Open console
2. Select Edit -> Profile Preferences
3. Select tab: Title and Command
4. Check box 'Run command as a login shell'
5. Restart terminal

Answer 2

Type bash --login from your terminal. And then give rvm use 2.0.0

Answer 3

It seems like your rvm does not load ".bash_profile" properly. I have done to fix it in MAC OS X or Ubuntu 14.04 by opening terminal and write:

source ~/.rvm/scripts/rvm

Answer 4

My env is OSX Yosemite. Had the same issue .... solved by adding following

1) edit and add [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" to .bash_profile file

2) Restart terminal and try RVM command again

Answer 5

If you don't want that every time you open a terminal, do the suggestion above again, just add

source ~/.rvm/scripts/rvm

at the end of ~/.bashrc

Answer 6

The error is due to rvm is not running as in login shell. Hence try the below command:

/bin/bash --login

You will able run rvm commands instantly as login shell in terminal.

Thanks!

Answer 7

Same principle as other answers, just thought it was quicker than re-opening terminals :)

bash -l -c "rvm use 2.0.0"

Answer 8

You need to add source ~/.rvm/scripts/rvm to ~/.your_shellrc file. From now when you load a shell, rvm will be loaded.

For example:

if you are using zsh shell, need to add in ~/.zshrc file

if you are using bash shell, need to add in ~/.bashrc file

And then open a new tab to see the effect.

Answer 9

For me in Ubuntu(18.08), I have added below line in .bashrc and it works.

 source /home/username/.rvm/scripts/rvm

Please add this line.

Answer 10

From a new Ubuntu 16.04 Installation

1) Terminal => Edit => Profile Preferences

2) Command Tab => Check Run command as a login shell

3) Close, and reopen terminal

rvm --default use 2.2.4

Answer 11

FWIW- I just ran across this as well, it was in the context of a cancelled selenium run. Perhaps there was a sub-shell being instantiated and left in place. Closing that terminal window and opening a new one was all I needed to do. (macOS Sierra)
