Reproduce the source-build fallback with node index.js --purs-ver=0.15.7, then inspect index.js around taskGroups, getCurrentTask at line 308, and the task transition at line 376. The fix is complete when the fallback no longer throws while selecting the build task and the installer output remains coherent through the build process.

Written by the indexing model from the issue text.

Description

I was trying to force the installer to build PureScript from source by modifying supportedPlatforms (removing all platforms) and architecture check (so it would always be false). When doing so, the installer fails with the following output:

/.../npm-installer (master*=) % node index.js --purs-ver=0.15.7                           
✖ Check if a prebuilt 0.15.7 binary is provided for linux
  No prebuilt PureScript binary is provided for x64 architecture.

See troubleshooting suggestions in https://github.com/purescript/purescript/blob/master/INSTALL.md
▬ Download the prebuilt PureScript binary
▬ Verify the prebuilt binary works correctly
▬ Save the downloaded binary to the npm cache directory

↓ Fallback: building from source

Node.js v19.6.1

The problem is somewhat fixed with the following patch (the output would be slightly messed up. I guess there's a better fix):
