Node JS version manager not working



Using NodeJs on c9 from a long time.
But from yesterday I am getting error and not able to run server,
nvm command not found when tried to switch version.
Then I created a new workspaces but now I am still getting same error.
bash: nvm: command not found

Please help


on which workspace do you see this? Most likely something have changed your .profile file to not source at startup
