Answer 1

You need to update the g++ compiler version in your linux system. To update the compiler just run the commands below:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

sudo apt-get update

sudo apt-get install gcc-4.9 g++-4.9

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9


npm install bcrypt --save

Answer 2

Be sure you are in a stable version of node too. If you are working with n, you only need to:

sudo n stable

And then again:

npm install bcrypt --save

And it worked for me.

Answer 3

If this is an error you are facing when using something like Travis CI, consider using npm install --build-from-source.

Answer 4

Check your node version and then go to this link https://github.com/kelektiv/node.bcrypt.js to match compatible bcrypt version with your node.js version

I am using node.js v14.7.0 and when I tried to run 'npm install bcrypt or bcryptjs' it gives me errors then I run npm install bcrypt@5.0.0

and the error fixed.

Version Compatibility

Answer 5

From: Cannot find module 'bcrypt'

Use bcrypt version according to node version.

Try to install bcrypt npm package separately like this If your node version is 8 use this command line

npm install bcrypt@1 --save

If your node version is 10,11 use this command line

npm install bcrypt@3 --save

maybe its will help you..

PS For me the second cmd worked and my Node version is 14.

In my case, npm rebuild alone didn't solved it. I also had to:

$ npm install -g node-gyp
$ sudo apt-get update
$ sudo apt-get install build-essential
$ npm rebuild

npm rebuild was trying to run make.
