Node - was compiled against a different Node.js version using NODE_MODULE_VERSION 51

Question

You need to remove the module folder (bcrypt) from the node_modules folder and reinstall it, use the following commands:

$ rm -rf node_modules/bcrypt
$ npm install
// or
$ yarn

I had the same problem and nothing mentioned here worked for me. Here is what worked for me:

1. Require all dependencies you need in the main.js file that is run by electron. (this seemed to be the first important part for me)
2. Run npm i -D electron-rebuild to add the electron-rebuild package
3. Remove the node-modules folder, as well as the packages-lock.json file.
4. Run npm i to install all modules.
5. Run ./node_modules/.bin/electron-rebuild (.\node_modules\.bin\electron-rebuild.cmd for Windows) to rebuild everything

It is very important to run ./node_modules/.bin/electron-rebuild directly after npm i otherwise it did not work on my mac.

I hope I could help some frustrated souls.

You have to rebuild the package and tell npm to update it's binary too. Try:

npm rebuild bcrypt --update-binary

@robertklep answered a relative question with this command, look.

Only rebuild haven't solved my problem, this works fine in my application.

Hope it helps!

Simply run:

npm uninstall bcrypt

Followed by:

npm install bcrypt (or npm install, if bcrypt is declared as dependency in your package.json file)
