Incorrect NODE_MODULE_VERSION when using ava

问题

I write an Electron app that uses nodegit. For my test part I use ava in combination with Spectron to test my app. All of my tests work - including functions which use nodegit in my app.

In addition to the tests described above I made also a pure non-Electron test file in which I import nodegit directly.

 import * as nodegit from 'nodegit';

Executing this test now via ava returns this:

node_modules\.pnpm\nodegit@0.27.0\node_modules\nodegit\build\Release\nodegit.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 82. This version of Node.js requires
NODE_MODULE_VERSION 83. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).
    at Module._extensions..node (internal/modules/cjs/loader.js:1122:18)

Where exactly does version 82 come from? I only have nodejs 14.15.0 installed, which uses version 83 as expected. Why does node think the version is a mismatch where it works actually in my app? This is how my package.json looks like:

  "devDependencies": {
    "ava": "^3.13.0",
  },
  "scripts": {
    "ava": "node_modules/.bin/ava",
     ...
  },
  "ava": {
    "files": [
      "*.ts"
    ],
    "extensions": [
      "ts"
    ],
    "require": [
      "ts-node/register"
    ],
    "nodeArguments": [
      "--napi-modules",
      "--experimental-modules"
    ]
  },

I built nodegit myself and in the config.gypi file it even refers to:

    "node_module_version": 83,

I made a super simple reproducible example: https://github.com/Githubber2021/node_module_version-issue

% node --version
14.15.0
% npm install
% npm run ava
... error

Can anyone explain me if this a bug or where version 82 comes from?

This could be one of two things:

The native dependency you're loading provides prebuilt binaries via prebuild -- This is probably the case
The native dependency you're loading is downloaded as source code and building the binary is up to you.

According to nodegit's README,

"NodeGit will work on most systems out-of-the-box without any native dependencies."

But it looks like you need at minimum nodegit@0.27.x to get prebuilt binaries from use Node 14. Source

So the 82 you're seeing comes from the ABI version that the prebuilt binary was compiled against. Since you're already using nodegit@0.27.x, then somehow you've ended up with the prebuilt binaries for the wrong ABI.

Here's a repo I use that lists out all the various binaries for different versions, so you can see how this might happen: https://github.com/lovell/sharp/tree/v0.25.3

I develop in Electron and for Electron I use a command like this to get the correct version of Electron to run npm rebuild against.

npm rebuild --runtime=electron --target=8.5.3 --disturl=https://atom.io/download/atom-shell

I don't know exactly what the equivalent is for plain node, but let me know if this gets you closer and if so I'll see what I can find.

Hey) I think I can solve your problem, just try this:

"engines": {
  "node": ">=14.0.0"
},

to your package.json and remove node_modules and do npm i in your project directory. It should help
