bcrypt not installing on ubuntu

Question

I tried to install bcrypt in Ubuntu but got following error. I can't understand error message properly. Here is some discussion regarding to the same problem : https://github.com/ncb000gt/node.bcrypt.js/issues/90 but still no solution found.

I have also tried to update npm(npm install -g npm) and installing the bcrypt with no luck.

isha@isha-ubuntu:~/Documents/xpressnepal$ sudo npm install
npm http GET https://registry.npmjs.org/bcrypt/0.7.7
npm http 304 https://registry.npmjs.org/bcrypt/0.7.7
npm http GET https://registry.npmjs.org/bindings/1.0.0
npm http 304 https://registry.npmjs.org/bindings/1.0.0

Answer 1

Use the latest stable version of node.js. bcrypt hasn't been ported to node 0.11.x.

If you are using a git clone, simply cd into the tree and checkout 0.10.26-release:

git checkout v0.10.26-release
fetch

Then configure, make, and install as usual. Then try installing bcrypt again:

npm install -g bcrypt

Credit goes to yanhan. He pointed me in the right direction. I just wanted to post the specific commands that would fix it.

Answer 2

i have same problem but i fixed it

i used instead of npm yarn

yarn is package manager like npm

first install yarn your system then use this command to install bcrypt

yarn add bcrypt
