Cannot install packages using node package manager in Ubuntu
(19 answers)
Closed 2 years ago.
I am having problems installing an npm package called "bcrypt" on my Ubuntu system.
This is what I did:
sudo apt-get update
sudo apt-get install nodejs
sudo apt-get install npm
sudo npm install bcrypt
This is what I got:
when typing: sudo npm install bcrypt
npm http GET https://registry.npmjs.org/bcrypt
npm http 304 https://registry.npmjs.org/bcrypt
npm http GET https://registry.npmjs.org/bindings/1.0.0
npm http GET https://registry.npmjs.org/nan/1.3.0
npm http 304 https://registry.npmjs.org/nan/1.3.0
npm http 304 https://registry.npmjs.org/bindings/1.0.0
> bcrypt#0.8.0 install /home/gatsu/salongapp/salongapp/node_modules/bcrypt
> node-gyp rebuild
/bin/sh: 1: node: not found

The package does not get placed in this folder:
/home/gatsu/salongapp/salongapp/node_modules/bcrypt
Any thoughts?

Answer 1

in ubuntu if you install nodejs using apt, the command for nodejs will be nodejs while commonly command line name used for nodejs is node.
Here, bcrypt assumes the command as node which is not available.
Try setting alias for nodejs as node like this
alias node='nodejs'
and then try to install bcrypt
sudo npm install bcrypt
U can set aliases in .bash_aliases file in home folder to permanently set the alias node.
