🎛 Configuration (.babelrc, package.json, cli command)

Running on node 22, nothing fancy in the package.json:

"devDependencies": {
    "@parcel/transformer-vue": "^2.12.0",
    "parcel": "^2.12.0"
  },
  "scripts": {
    "build": "parcel build --no-cache --public-url ./ src/*.html",
  },
  "dependencies": {
    ...
    "vue": "^3.4.31"
  },
  "optionalDependencies": {
    "@parcel/watcher-linux-x64-glibc": "^2.4.2-alpha.0"
  }

The optional dependency was needed, otherwise it would result in another bug reported here.

And the typescript config looks as follows:

{
  "compilerOptions": {
    "lib": [
      "dom",
      "es2016"
    ]
  }
}

🤔 Expected Behavior

It compiles

😯 Current Behavior

It throws that error

💁 Possible Solution

💻 Code Sample

🌍 Your Environment

Software	Version(s)
Parcel	2.12.0
Node	22
npm/Yarn	npm
Operating System	Linux

...but it works on Windows!

After a lot of difficult search, the following workaround seems to do the trick:

npm install -O @swc/core-linux-x64-glibc
npm install -O @swc/core-linux-x64-gnu

@dagnelies-elo Had this issue when building Parcel on a DigitalOcean App Platform instance, this fixed it. Any idea why these dependencies aren't automatically installed if required?

...sorry ...I have no clue about the logic behind these optional dependencies
