Installing Node.js Using Node Version Manager (nvm)
Set up Node.js on OS X Yosemite.
What is nvm?
Node Version Manager (nvm) is a tool that allows you to manage multiple versions of Node.js on the same machine. Each version runs in its own isolated environment, so you can safely switch versions without affecting the whole system.
Start by running the install script using cURL:
$ curl https://raw.githubusercontent.com/creationix/nvm/v0.24.0/install.sh | bash
Note: As at the time of writing, 0.24.0 is the latest version of nvm. Check the latest release before installing.
The script installs nvm to
~/.nvm, inside your home directory. It also adds a line to your profile (
~/.profile depending on which shell you use).
nvm command will be available when you restart your shell, or immediately if you source your profile manually:
$ source ~/.bashrc # or ~/.zshrc or ~/.profile
Make sure nvm is installed correctly by running:
$ nvm --version
This command should print out the installed version of nvm.
Install the latest stable release of Node.js with the following command:
$ nvm install stable
Replace stable with a version number to install a specific version.
Select the installed version in any new shell using:
$ nvm use stable
Now you can use different versions of Node.js in each of your shell instances. But if you want to set the latest version as default for any new shell, run:
$ nvm alias default stable
Make sure Node.js is installed correctly by checking the version:
$ node -v
For more nvm commands run
nvm help or see the Usage section in the README.
