Win10 x64, node js - 14.0.0, npm - 6.14.4.
Does anybody have any idea how to fix issue with gyp?

#2058

[AlexanderNaiden]

The issue occurs only during npm ci command but npm i works fine. However without npm ci command working correctly I can't do commit.
The error occurs with any of version python 3.7 or 2.7.
I've removed python 3.7 and then
I've done Option 1
Install all the required tools and configurations using Microsoft's windows-build-tools using npm install --global --production windows-build-tools from an elevated PowerShell or CMD.exe (run as Administrator).
Now I have python 2.7 because it was installed with windows-build-tools.
And it does't work anyway.
I ran all commands in VS Code 1.44.2
From my side I don't see clearly answer in [https://github.com//issues/2058]

I just started seeing this too, yesterday this wasn't happening? Was there a package update that triggered this?

[AlexanderNaiden]

I didn't add any library so there are no changes in package.json or package-lock.json. I can provide package.json and package-lock.json if necessary. Also I've tried decrease nodejs version to version 12.16.3 LTS (npm version remains the same 6.14.4) but it didn't help.

There's two issues here:

1. fsevents is macOS only. It specifies an os field in its package.json but this is apparently ignored by npm ci. fsevents used to provide prebuilt binaries up to fsevents@1.2.9 which meant for those versions it didn't attempt to compile. Those binaries are not provided for later versions of fsevents (e.g. 1.2.12 reported in this issue). See windows: fsevents v1 is getting built  fsevents/fsevents#301. This may be addressed "soonish" by a release containing Only build fsevents on macOS fsevents/fsevents#322.
2. The AttributeError: 'MSVSProject' object has no attribute 'items' is probably a bug in gyp is likely something that needs to be fixed upstream (https://github.com/nodejs/gyp-next) and then synced back here.

This is exactly the same issue as #2058. node-gyp can't possibly control what is inside binding.gyp of the modules you are trying to build.

The fsevents package is now fixed, the solution here is to update the dependencies.
