[SOLVED] NPM: no such file or directory

Issue

I'm using Ubuntu 16.04 I removed NPM in order to install older version. (I can't exactly command which I used). now I can't install it again. npm -v output: bash: /usr/bin/npm: /usr/bin/nodejs: bad interpreter: No such file or directory which npm output: /usr/bin/npm

curl -L http://npmjs.org/install.sh | sudo sh

Output:

`install npm@latest
 fetching: https://registry.npmjs.org/npm/-/npm-5.5.1.tgz
 module.js:544
    throw err;
    ^

 It worked`

UPD: Solved. Remove node/nodejs/npm completely and remove all relative folders a then reinstall via NVM helped. https://www.digitalocean.com/community/tutorials/how-to-install-node-js-with-nvm-node-version-manager-on-a-vps

Solution

Better way to install nodejs is via nvm. Here you can install/use multiple version of nodejs in a machine.

https://github.com/creationix/nvm

then

nvm install $vesionNo

nvm use $versionNO

// for default 

nvm alias default node
