'flutter pub get' 失败 - “因此，因为 fstore 依赖于 sdk 中的任何 flutter_test，版本解析失败。”

Question

我最近升级到 Flutter 的最新版本。结果，我的应用程序无法加载并立即失败。错误似乎是由于 Flutter 版本造成的。我试图降级，但这没有成功。

这是控制台的输出。

Running "flutter pub get" in source...
Because every version of flutter_test from sdk depends on vector_math 2.1.0-nullsafety.3 and fstore depends on vector_math 2.0.8, flutter_test from sdk is forbidden.
So, because fstore depends on flutter_test any from sdk, version solving failed.
pub get failed (1; So, because fstore depends on flutter_test any from sdk, version solving failed.)

我尝试更改为开发频道并升级。这没有用。我切换到稳定和升级 - 这也不起作用。我试图降级并恢复，这也没有奏效。

关于如何解决这个问题的任何想法？- 我是一个新手编码器！

我的 pubspec.yaml 如下：

name: fstore
description: Mobile commerce app by Flutter

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

Answer 1

错误：Because every version of flutter_test from sdk depends on...

意味着 flutter_test 依赖于版本低于您在另一个依赖项中指定的版本的依赖项。

要解决此问题，请打开 pubspec.yaml，并删除问题依赖项的版本号：vector_math: 2.0.8>>vector_math:

因为 sdk 中的 flutter_test 的每个版本都依赖于... sdk 中的 flutter_test 被禁止，版本解析失败
