Solution 1: lengthy method is : Install all dependencies first.

npm install -g windows-build-tools, npm install -g node-gyp

then, install bcrypt : npm install bcrypt

Solution 2: easy method. No dependencies installation required.

npm install bcryptjs

...You might have installed bcrypt but it seems like the installation was not successful for some reason. check the package.json file. If you cannot find bcrypt, the installtion was unsuccessful. You have to install again.

As everyone explained, it because of lack dependencies that your installation was unsuccessful. You can checkout the required dependencies in the link: https://www.npmjs.com/package/bcrypt

Note: To use bcrypt: var bcrypt = require('bcrypt'); .....

to use bcryptjs. var bcrypt = require('bcryptjs');

for reference: https://www.npmjs.com/package/bcrypt https://www.npmjs.com/package/bcryptjs

Before using npm install, change the package.json file dependencies, i.e.

"bcrypt":"0.7.6"

to

"bcrypt":"*"

This worked for me.

1) Delete any bcrypt folder in nodemodules folder, folder may have been created due to your repeated tries. (C:\Program Files\nodejs\node_modules\npm\node_modules)

2) run this code npm install --save bcryptjs e.g -

C:\Projects\loginapp>npm install --save bcryptjs

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

It seems that bcrypt was depreciated at version 1.0.3 as it was susceptible to a wrap-around bug. NPM recommends installing version 2.0.0.

So, if you wish to save it, just run the command:

npm install bcrypt@2.0.0 --save

If none of these examples didn't work, you should try to downgrade Node version installed:

E.g from Node version 10 to version 9

@joeytwiddle If even that won't work, the best solution is to install `bcryptjs`. It has zero dependencies and it's not influenced by OS used.But first it needs to be uninstalled `bcrypt`. – Radisav Savkovic May 11 '19 at 12:30

This happened to me as I was installing a package from github that had an older version of bcrypt as a dependency.

Just uninstall bcrypt to clear out the old version and install a new version:

npm uninstall bcrypt

I followed some course, and for me it didn't work. My mistake was:

Node Version vs Bcrypt Version
0.4 <= 0.4
0.6, 0.8, 0.10 >= 0.5
0.11 >= 0.8
4 <= 2.1.0
8 >= 1.0.3
10, 11 >= 3
12 >= 3.0.6

I had the same issue, after I installed the bcrypt particular version depends on your node version, it started to working.

In my case my nodeJS version was 12.3.0 , so I installed by specifying the version " npm install bcrypt@3.0.6."

I hope it will resolve the issue.

First delete bcrypt module from your node modules. Then try the below steps:

1) npm install node-gyp -g

2) npm install bcrypt -g

3) npm install bcrypt -save

This will definitely resolve the issue.

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

And then again:

The problem could be because there is no this essential

sudo apt-get install -y build-essential python

Then agregate bcrypt with if you're using npm:

npm install bcrypt
npm rebuild

or if you're using yarn:

yarn add bcrypt
yarn install
yarn build

First check node-modules folder for a folder with this name bcrypt. If it exists with another name just rename it; for example bcrypt-pbkdf must be edited to bcrypt. If there isn't such a folder, do this in cmd:

npm install node-gyp -g
# bcrypt reqired node-pre-gyp
npm install -g node-pre-gyp
npm install bcrypt -g
npm install bcrypt --save

For me, it was because bcryptjs has a different name.

To fix it simply,

cd node_modules Go to node_modules folder on your application
ln -s bcryptjs bcrypt OR for Windows mklink /D bcryptjs bcrypt

This creates a link of bcryptjs directory to bcrypt.

In my case, after running the install commands and the commands suggested by others, my package.json file was not being updated. I manually included this dependency in my package.json file like below:

"dependencies": {
    ...
    "bcrypt": "5.0.1"
    ...
}

And then saved the file and ran npm install --save -g, this installed the missing packages.
