flutter pub get and dart pub --trace get --no-precompile log #2928

Closed Turfedin closed 2 months ago

Turfedin commented 3 years ago

This is the first time I'm filling in a git issue, so please if I'm doing something wrong kindly share your feedback.

flutter pub get fails and asks me to include the following logs here.

What I did: I was checking out to previous versions of my flutter project, and the automatic pub get started to give me this error. Even after I came back to my last version the error remained.

The command recommended above is not correct and provokes the following error: Cannot specify arguments before a command. Sorry, I did not manage to correct it, if it is at all possible.

Lastly, here is mu flutter doctor -v:

Thanks for posting.

This is a bug. Seems like an invalid assumption in the lockfile validation.

Could you paste your pubspec.lock file here? It seems to be "corrupted" I wonder if pub did that...

To work around, try deleting your pubspec.lock and run dart pub get again.

Turfedin commented 3 years ago

I solved the issue now. I deleted the pubspec.lock file as well as the files:

Not sure if it was all necessary, but afterwards dart pub get finally worked as expected.

This is the version of my pubspec.lock the closest to when my bug happened, but I cannot promise it is exactly the same unfortunately:

So the problem with the pubspec.lock is the win32: line. Looking at the generating code this could not be generated by pub:

  String serialize(String packageDir) {
    // Convert the dependencies to a simple object.
    var packageMap = {};
    packages.forEach((name, package) {
      var description =
          package.source.serializeDescription(packageDir, package.description);

      packageMap[name] = {
        'version': package.version.toString(),
        'source': package.source.name,
        'description': description,
        'dependency': _dependencyType(package.name)
      };
    });

    var data = {
      'sdks': mapMap(sdkConstraints,
          value: (_, constraint) => constraint.toString()),
      'packages': packageMap
    };
    return '''
# Generated by pub
# See https://dart.dev/tools/pub/glossary#lockfile
${yamlToString(data)}
''';
  }

Probably the contents of pubspec.lock was modified by hand by accident somehow.

Still we need to fix the validation code, such that it doesn't crash.

sigurdm commented 2 months ago

This has been fixed somewhere along the way.

The message is now:

Failed parsing lock file:

Error on line 449, column 8 of pubspec.lock: Expected a map
    ╷
449 │   win32:
    │        ^
    ╵

Consider deleting the file and running `dart pub get` to recreate it.
