Node.bcrypt.js: Incorrect NODE_MODULE_VERSION

[megmut]

After doing a deployment to a Ubuntu, trying to start the project throws an error.

module.js:664
  return process.dlopen(module, path._makeLong(filename));
                 ^

Error: The module '/home/user/ml-interface/node_modules/bcrypt/lib/binding/bcrypt_lib.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 46. This version of Node.js requires
NODE_MODULE_VERSION 57. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).

I have tried doing a npm rebuild inside of bcrypt, as well as updating the binaries

> [email protected] install /home/nmordecai/ml-interface/node_modules/bcrypt
> node-pre-gyp install --fallback-to-build

[bcrypt] Success: "/home/nmordecai/ml-interface/node_modules/bcrypt/lib/binding/bcrypt_lib.node" is installed via remote
[email protected] /home/nmordecai/ml-interface/node_modules/bcrypt

Though it says it was successful, it is not.
npm version: 5.6.0
node version: 8.9.1
os: linux ubuntu 16.04.3 LTS

I'm having the same issue. Any update on how to fix this?

[megmut]

I fixed the issue by installing https://www.npmjs.com/package/bcryptjs it's the same as bcrypt, however it's already bundled with no dependencies, which fixed by issue. Hope this helps.

[brentsink]

That works perfectly. Thanks!

[megmut]

Glad I could help :)

I'm currently experiencing this issue. Switching to bcryptjs isn't an option because bcrypt is a dependency of one of my dependencies rather than a direct dependency.

I've tried deleting both node_modules and package-lock.json and running npm i multiple times. I've also tried npm rebuild and npm rebuild bcrypt --update-binary. I'm using node v9.2.0 (sudo node --version prints the same version).

This issue shouldn't have been closed considering the only "solution" was to just use a different
(but compatible) library.

Try npm rebuild bcrypt --build-from-source

npm rebuild should have downloaded the current version for you.

We are sorry that we don't have a better solution. NodeJS does not provide ABI compatibility reliably. So native modules and NodeJS ABIs must match. This involves rebuilding the module whenever the NodeJS version changes.
