How to fix: "error [email protected]: The platform "linux" is incompatible with this module."

Question

I want to deploy my website to Heroku but I get the next error:

error [email protected]: The platform "linux" is incompatible with this module.
error Found incompatible module.

I've already tried upgrading yarn, node but it didn't help. I use macOS Mojave v 10.14.5 and I cannot understand why is linux here.

Answer 1

I removed lines

fsevents@^1.2.7, fsevents@^2.0.6:
  version "2.0.7"
  resolved "https://registry.yarnpkg.com/fsevents/-/fsevents-2.0.7.tgz#382c9b443c6cbac4c57187cdda23aa3bf1ccfc2a"
  integrity sha512-a7YT0SV3RB+DjYcppwVDLtn13UQnmg0SWZS7ezZD0UjnLwXmy8Zm21GMVGLaFGimIqcvyMQaOJBrop8MyOp1kQ==

and

  optionalDependencies:
    fsevents "^2.0.6"

from yarn.lock. Next I removed

    "fsevents": "2.0.7",

from resolutions key in package.json

Finally on yarn install I can see

info [email protected]: The platform "linux" is incompatible with this module.
info "[email protected]" is an optional dependency and failed compatibility check. Excluding it from installation.

and

success Saved lockfile.

You do not need this module because of this is only for MacOS

Native access to MacOS FSEvents in Node.js

https://www.npmjs.com/package/fsevents

Answer 2

yarn --ignore-platform This will fix the issue. As the name suggests it'll ignore the platform(Mac/Linux) and install those dependencies.

Answer 3

I'm getting the error now, but Heroku excludes fsevents and results in a successful deploy.

info [email protected]: The platform "linux" is incompatible with this module.
remote:        info "[email protected]" is an optional dependency and failed compatibility check. Excluding it from installation.

I didn't modify yarn.lock or any other files. I ended up at the post because I was curious about the error and now I know it's for macOS only. In other words ignore the error and leave yarn.lock alone.
