BASH:/usr/bin/npm:no such file or directory

A very rotten Ubuntu server, a variety of problems mess out. NPM is always not up to the latest version (always show 1.4), so I simply deleted, the result again to install but not loaded, if apt-get install npm installed, get the following error:

  The following packages has unmet Dependencies:npm:Depends:nodejs but it isn't going to be installed Depe Nds:nodejs-dev Depends:node-request But it isn't going to being installed DEPENDS:NODE-MKDIRP but it's not going to be installed Depends:node-minimatch But it's not going to being installed depends:node-semver but it's not going to B E installed Depends:node-ini But it isn't going to being installed DEPENDS:NODE-GRACEFUL-FS but it's not going to be Installed Depends:node-abbrev But it isn't going to being installed depends:node-nopt but it's not going to be instal    LED Depends:node-fstream But it isn't going to being installed Depends:node-rimraf but it isn't going to being installed Depends:node-tar but it isn't going to being installed Depends:node-which but it isn't going to being installede:unabl E to correct problems held broken packages.  

The official website only offered this method, and found that the method offered on its GitHub homepage was: curl -L https://npmjs.com/install.sh | sh success.

Still not available:

npm -vbash: /usr/bin/npm: No such file or directory

A random search, to a variety of solutions to the trial, also did not really solve, that only their own thinking about:

1. NPM is loaded, so where to go (found)
2. Direct to installation directory execution (succeeded)
3. Then try it on the soft chain (success)
