Version solving errors are hard to parse

[gaaclarke]

The error is very difficult to parse because proper nouns and code aren't delineated somehow.

Seen

$ ~/dev/dart-sdk/sdk/xcodebuild/DebugX64/dart run test
Resolving dependencies in /Users/aaclarke/dev/dart-sdk/sdk/pkg/kernel... (1.0s)
Because every version of expect from path depends on smith any which is forbidden, expect from path is forbidden.
So, because kernel depends on expect from path, version solving failed.

Expected

$ ~/dev/dart-sdk/sdk/xcodebuild/DebugX64/dart run test
Resolving dependencies in /Users/aaclarke/dev/dart-sdk/sdk/pkg/kernel... (1.0s)
Because every version of `expect` from `path` depends on `smith` any which is forbidden, `expect` from `path` is forbidden.
So, because `kernel` depends on `expect` from `path`, version solving failed.

That isn't quite right since I don't understand "any which is forbidden".

Actually, not sure I triaged this correctly. I missed these are SDK packages. Are those handled differently?

Can you share the pubspec.yaml you're trying to resolve, including the pubspec.yaml inside your path dependency?

I wonder if this would be fixed by #3196, in particular I'm curious if it just failed to tell you that smith does not exist.

The pubspec.yaml is in the dart sdk itself: https://github.com/dart-lang/sdk/blob/main/pkg/kernel/pubspec.yaml

The big problem is that it hard to read because there is no delineation between package names and pubspec concepts and English. For example, I didn't author the pubspec so the idea that expect is a package name wasn't even on my radar. I still have a hard time understanding what it says.
