-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
