Can I build @parcel/source-map without xcode?

[danieltroger]

Hi,
I solved my other issue by using my iPad instead. (iOS 14.3, node v14.13.1, npm v6.14.8)

However now for some reason the source-map package needs PYTHON to run which for some reason needs XCODE. Is this intentional? I thought the great thing with writing things in js was cross-platformability. I thought one could even run parcel in a browser…

Is there some way around this? I have clang installed if that's needed to build something. Can I configure it to use that instead? How does this work on linux, which also doesn't have xcode?

Uh-oh:~/[project_dir] mobile% npm install

> @parcel/source-map@2.0.0-alpha.4.21 install /private/var/mobile/[project_dir]/node_modules/@parcel/source-map
> node-gyp-build

Please open an issue about this at https://github.com/nodejs/node-gyp#readme.

return GetStdoutQuiet(['xcodebuild', '-version', '-sdk', sdk, infoitem])

As you can see, on macOS, this helper is installed via the Xcode CLI Tools and used to find various paths.

Thank you, I opened nodejs/node-gyp#2385.

Let's hope they're interested in supporting iOS.
