解决依赖关系：pub 已完成，退出代码为 1

Question

我有这个依赖冲突：

$ flutter pub upgrade --dry-run
Resolving dependencies...
Because image >=2.1.14 <3.0.0-nullsafety.0 depends on archive ^2.0.0 and image >=2.0.4 <2.1.14 depends on archive >=1.0.16 <3.0.0, image >=2.0.4 <3.0.0-nullsafety.0 requires archive >=1.0.16 <3.0.0.
And because flutter_launcher_icons >=0.7.1 <0.9.0 depends on image ^2.1.1 and every version of flutter_driver from sdk depends on archive 3.1.2, flutter_launcher_icons >=0.7.1 <0.9.0 is incompatible with flutter_driver from sdk.
So, because gallery depends on both flutter_driver any from sdk and flutter_launcher_icons ^0.8.1, version solving failed.
pub finished with exit code 1

尝试过

我改了：

flutter_launcher_icons: "^0.8.1"

至：

flutter_launcher_icons: "^0.9.0"

但也无济于事。

问题

我不知道如何解决冲突。有没有我可能遗漏的解决此类冲突的标准方法？

Answer 1

您可以运行在您的项目终端

flutter pub upgrade --major-versions

Answer 2

因为你的项目依赖于flutter_launcher_icons和flutter_driver 并且这两个包都依赖于具有不同版本的第三个包 archive。

flutter_launcher_icons: "^0.8.1" 依赖于 archive: ">=2.0.4 <3.0.0-nullsafety.0" 而来自 sdk 的 flutter_driver 依赖于 archive: 3.1.2, 所以存在解析版本冲突 archive包。

因此，要解决此冲突，您必须在项目的 pubspec.yaml 文件中添加手动条目。

dependency_overrides:
  archive: 3.1.2  //any version you want for resolution.
