Cannot install bcrypt node.js module on Centos Server

Question

I'm trying to install bcrypt on CentOS server but I got the following error:

info postuninstall [email protected]
ERR! [email protected] install: `make build`
ERR! `sh "-c" "make build"` failed with 2
ERR!
ERR! Failed at the [email protected] install script.
ERR! This is most likely a problem with the bcrypt package,
ERR! not with npm itself.
ERR! Tell the author that this fails on your system:
ERR!     make build
ERR! You can get their info via:
ERR!     npm owner ls bcrypt
ERR! There is likely additional logging output above.

What Can I do to solve this? Thanks,

Solution 1

I got the same issue doing npm install bcrypt. The other option is to install it from source.

git clone git://github.com/ncb000gt/node.bcrypt.js.git
cd node.bcrypt.js
node-gyp configure
node-gyp build

Rename the node.bcrypt.js folder to bcrypt, and move it into your node_modules of your project.

You can install node-gyp by doing npm install -g node-gyp (-g installs it globally).

Solution 2

There is also a native-js version of bcrypt which does not require compiling. https://github.com/shaneGirish/bcrypt-nodejs

npm install bcrypt-nodejs

The api is very similar to the compiled version. The following is taken directly from the readme

Basic usage:

Synchronous

var hash = bcrypt.hashSync("bacon");

bcrypt.compareSync("bacon", hash); // true
bcrypt.compareSync("veggies", hash); // false

Asynchronous

bcrypt.hash("bacon", null, null, function(err, hash) {
    // Store hash in your password DB.
});

// Load hash from your password DB.
bcrypt.compare("bacon", hash, function(err, res) {
    // res == true
});
bcrypt.compare("veggies", hash, function(err, res) {
    // res = false
});

Solution 3

For me the answer was to ensure that I had gcc, openssl and node-gyp installed.

To install gcc and openssl, use yum:

sudo yum install gcc-c++ openssl-devel

To install node-gyp (globally), use npm:

npm install -g node-gyp

Then the npm install of bcrypt worked just fine on centos

Solution 4

Pre-built binaries are usually available for bcrypt in a few hours after a new release of bcrypt or after a few days after a new NodeJS version is released.

However, remember that binaries are only provided as a convenience.

If you see an error such as:

`You need the following packages on CentOS / RHEL / Fedora

• gcc-c++ - In order to install a compiler chain to compile the node modules.
• make - To run the generated Makefile by node-gyp, which invokes compilers in order
• python - RHEL and CentOS come with the required version of python installed

Make sure all dependencies are installed with this command,

yum install -y gcc-c++ make

and then proceed with the bcrypt installation.

I think openssl was missing in my system. After installing my problem solved

For me this didn't work until I'd installed other pre-requisites which enabled npm install to work just fine anyway. However you certainly gave me a clue in which direction to go. So I'll upvote you and post an alternative answer.

bcrypt is a headache, I'm migrating to this. Thanks for the alternative.
