-bash: nvm: command not found

Question

When I install nvm using the command wget or curl (OS X El Capitan 10.11.4), the console prints

=> nvm is already installed in /Users/weichuang/.nvm, trying to update using git

=> 
=> Source string already in /Users/weichuang/.bashrc
npm ERR! error in /usr/local/lib/node_modules/love: ENOTDIR: not a directory, open '/usr/local/lib/node_modules/love/package.json'
npm ERR! missing: npmlog@, required by [email protected]

=> You currently have modules installed globally with `npm`. These will no
=> longer be linked to the active version of Node when you install a new node
=> with `nvm`; and they may (depending on how you construct your `$PATH`)
=> override the binaries of modules installed with `nvm`:

=> If you wish to uninstall them at a later point (or re-install them under your
=> `nvm` Nodes), you can remove them from the system Node as follows:

     $ nvm use system
     $ npm uninstall -g a_module

=> Close and reopen your terminal to start using nvm

Though i Close and reopen my terminal to start using nvm,the problem is still -bash: nvm: command not found

Solution 1

Type in terminal

source ~/.nvm/nvm.sh
source ~/.profile
source ~/.bashrc

Solution 2

My answer is based on Mac OS X but I am sure it should work for other Linux based system.

Installing & using nvm on Mac OS X

• Install homebrew from here.

• Using homebrew install nvm

  brew update brew install nvm

• Create .nvm directory at ~/.nvm location.

  mkdir ~/.nvm

• Now if you don't have .bash_profile file setup for OS X terminal then please create a .bash_profile at the root level:

  nano ~/.bash_profile

• Paste below code in the .bash_profile and press CTRL + O and press enter to save .bash_profile file. Press CTRL + X to exit from editor:

  export NVM_DIR=~/.nvm source $(brew --prefix nvm)/nvm.sh

• Now either quite (CMD + Q) the terminal or run below command to load .bash_profile settings:

  source ~/.bash_profile

• Now run nvm ls command to get the list of all installed nodejs versions.
