How to fix 'Unsupported platform for fsevents@1.2.9: wanted {“os”:“darwin”,“arch”:“any”} (current: {“os”:“win32”,“arch”:“x64”})

Question

Testing binary Binary is fine npm WARN rollback Rolling back node-pre-gyp@0.12.0 failed (this is probably harmless):

EPERM: operation not permitted, lstat 'C:\Users\orca yoon\Documents\IonicProjects\starters\epic\node_modules\fsevents\node_modules'

npm notice created a lockfile as package-lock.json. You should commit this file.

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.9 (node_modules\fsevents):

npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.9: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

added 1105 packages from 1050 contributors and audited 53269 packages in 445.94s found 1 high severity vulnerability run npm audit fix to fix them, or npm audit for details

Answer 1

When seeing this kind of message on ionic or anywhere else, do run npm audit fix and see if you can successfully follow the given advice to resolve all "high severity vulnerability" issues and contribute the resulting updated dependencies back to the given codebase.

What's happening here is that a package called chokidar is being used to "watch" filesystem directories for "events" (like files being added). chokidar is a wrapper for Linux-, Windows-, and Mac-specific filesystem-watching packages, of which fsevents is the Mac variant. So, I am pretty sure anything that uses chokidar is going to have fsevents as an optional dependency, but as others have said, this WARN message can be safely ignored, as chokidar supports all common desktop architectures.

Answer 2

• First,

Run your command prompt or powershell as Administrator role. Then you'll get avoided with PERMISSION ERROR.

• Second,

Ignore npm audit fix. It only suggests you to renovate all of your package.json dependencies up-to-date. You should preserve the settings clarified in package.json.

• Third,

If you're working on ubuntu or OS X, you won't face this issue, I guess.

PS:

According to your reply, I'd like to think about the workaround.

• Remove the local node_modules & package-lock.json
• Clean npm cache by npm cache verify
• Update the global npm by sudo npm i -g npm
• Reinstall the local node_modules by npm i

Hope this might help.

Answer 3

I found a solution, this is what I did:

Open your package-lock.json.

Find node_modules/fsevents, inside this there is something called "os", I had only this:

 "os": [
        "darwin",
      ],

So my OS is windows 10 64 bits I just added my OS inside "os", the result is this:

 "os": [
        "darwin",
        "win32"
      ],

then save and is solved, after doing this I could install the package I was trying to install that I couldn't.

Answer 4

This warning will appear if you added IOS as platform to your project and run npm i on Windows or Linux. As you can't build IOS packages on these systems anyway you can safely ignore this warning.

Answer 5

You have to add win64 on package.json file

For example

{"os":"darwin,linux","arch":"any"} will replace with

{"os":"darwin,linux,win32,win64","arch":"any"}
