Electron/Bcrypt error (NODE_MODULE_VERSION X. This version of Node.js requires NODE_MODULE_VERSION X. Please try re-compiling or re-installing)

[rblmdst]

Hello Everyone

I am using Cypress for e2e test of one of the my project.

• cypress : 3.1.5
• Node : v10.15.0

I am currently trying to load/unload some fixtures in the Database before starting the test, for that purpose I used the cy.task command of cypress (described in this post https://glebbahmutov.com/blog/powerful-cy-task/ by @bahmutov ) in order to run the script that loads the fixture.

I am getting the following error when running cypress open

Error: The module '/home/modeste/Dev/o-food/node_modules/bcrypt/lib/binding/bcrypt_lib.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 64. 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`).

When making searches I found that the issue is related to electron version of node and the node version used to build bcrypt; the solution proposed by many people to solve the issue is to rebuild electron using electron-rebuild package like describe in the following links:

• https://stackoverflow.com/questions/46384591/node-was-compiled-against-a-different-node-js-version-using-node-module-versio
• https://stackoverflow.com/questions/45761864/nodejs-how-to-fix-different-node-module-version
• How to deal with NODE_MODULE_VERSION in electron onmyway133/blog#69

I have also tried to rebuild bcrypt using :

npm rebuild bcrypt --update-binary

I have tried all that without any success, none of the solution worked for me, I am still getting the error.

It is almost 4 days that I am locked on it and I can not progress in my test anymore.

Any help or clue will be welcomed.

Thank you

@rblmdst Are you using the correct version of Electron for electron-rebuild? You ought to be able to rebuild bcrypt against our version of Electron by using this from your application's root directory. Try this:

npx electron-rebuild -v 1.8.2 -w bcrypt

Hello @flotwig I have try the npx electron-rebuild -v 1.8.2 -w bcrypt and it is working now.
Thank you. 👍
