flutter pub run build_runner 构建已弃用

Question

当我运行

flutter pub run build_runner build --delete-conflicting-outputs

时，我收到此错误：

Deprecated. Use `dart run` instead.
[INFO] Generating build script completed, took 169ms
[WARNING] ../../../.pub-cache/hosted/pub.dev/built_value_generator-8.6.1/lib/src/dart_types.dart:65:21: Error: 'InvalidType' isn't a type.

This is likely caused by a misconfigured builder definition.

所以我运行

dart run build_runner build --delete-conflicting-outputs

并收到此错误：

我尝试将

gql: 0.13.0

添加到 dependency_overrides 但我再次遇到了同样的错误！

我正在使用

Flutter (Channel stable, 3.10.5, on macOS 13.2.1 22D68 darwin-arm64, locale en-US)

和

build_runner: ^2.4.5

如何解决？

Answer 1

您可以尝试通过修改

build_runner

来升级

pubsec.yaml

到最新版本（目前是2.4.7）

dev_dependencies:
...
build_runner: ^2.4.7
...

或

flutter pub upgrade build_runner

您还应该使用

清理所有颤振缓存

flutter clean

如果没有解决你的问题，你会尝试

dart run build_runner doctor

获取有关此错误的更多信息。

Answer 2

删除第一个 pubspec.lock 文件。

然后扑干净 扑扑 pubget

所以它会生成network.g.dart和pubspec.lock文件

flutter pub run build_runner 构建
