You can use curl:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.3/install.sh | bash

Or you can use wget:

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.31.3/install.sh | bash

To verify that nvm has been installed, do:

command -v nvm

which should output 'nvm' if the installation was successful.

Listing available remote versions for installation

nvm ls-remote

Installing a remote version

nvm install <version>

For example

nvm install 0.10.13

To list available local versions of node through NVM:

nvm ls

For example, if nvm ls returns:

$ nvm ls
     v4.3.0
     v5.5.0

You can switch to v5.5.0 with:

nvm use v5.5.0

INSTALLATION PROCESS

You can install Node Version Manager using git, curl or wget. You run these commands in Terminal on Mac OSX.

curl example:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.3/install.sh | bash

wget example:

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.31.3/install.sh | bash

TEST THAT NVM WAS PROPERLY INSTALLED

To test that nvm was properly installed, close and re-open Terminal and enter nvm. If you get a nvm: command not found message, your OS may not have the necessary .bash_profile file. In Terminal, enter touch ~/.bash_profile and run the above install script again.

If you still get nvm: command not found, try the following:

• In Terminal, enter nano .bashrc. You should see an export script almost identical to the following:

export NVM_DIR=”/Users/johndoe/.nvm” [ -s “$NVM_DIR/nvm.sh” ] && . “$NVM_DIR/nvm.sh”

• Copy the export script and remove it from .bashrc
• Save and Close the .bashrc file (CTRL+O – Enter – CTRL+X)
• Next, enter nano .bash_profile to open the Bash Profile
• Paste the export script you copied into the Bash Profile on a new line
• Save and Close the Bash Profile (CTRL+O – Enter – CTRL+X)
• Finally enter nano .bashrc to re-open the .bashrc file
• Paste the following line into the file:

source ~/.nvm/nvm.sh

• Save and Close (CTRL+O – Enter – CTRL+X)
• Restart Terminal and enter nvm to test if it's working

If you want to set some alias name to installed node version, do:

nvm alias <name> <version>

Similary to unalias, do:

nvm unalias <name>

A proper usecase would be, if you want to set some other version than stable version as default alias. default aliased versions are loaded on console by default.

Like:

nvm alias default 5.0.1

Then every time console/terminal starts 5.0.1 would be present by default.

Note:

nvm alias # lists all aliases created on nvm

List all the node versions installed

nvm ls
    v4.5.0
    v6.7.0

Run command using any node installed version

nvm run 4.5.0 --version or nvm exec 4.5.0 node --version
Running node v4.5.0 (npm v2.15.9)
v4.5.0

nvm run 6.7.0 --version or nvm exec 6.7.0 node --version
Running node v6.7.0 (npm v3.10.3)
v6.7.0

nvm run default --version or nvm exec default node --version
Running node v6.7.0 (npm v3.10.3)
v6.7.0

To install node LTS version

nvm install --lts

Version Switching

nvm use v4.5.0 or nvm use stable ( alias )

Remarks

The urls used in the above examples reference a specific version of Node Version Manager. It is most likely that the latest version is different to what's being referenced.
