Flutter 项目向我展示了一个带有建议解决方案的警告'Packages get' has not been run，
- 获取依赖项
- 升级依赖项
- 忽视
正如Darky所建议的那样，在此答案中继续"获取依赖项">
我试过了，但它向我显示了一个错误：
酒吧失败
/SoftSources/Flutter/flutter/bin/flutter --no-color packages get
Running "flutter packages get" in catalog...
Incompatible version constraints on test:
- flutter_test 0.0.0 depends on version 0.12.30+3
- sample_catalog depends on version 0.12.30+4
pub get failed (1)
Process finished with exit code 1
错误表明项目版本(或其他内容(存在问题，应该在我的颤振项目中在哪里更改它？
编辑：pubspec.yaml

或者，您可以在颤振时切换到主分支。因为你很可能克隆了一个基于 Flutter 主控的项目示例
来自Windows操作系统的人，仍然无法解决pub get failed (1; no message) exit code 1问题，您可以尝试以下步骤：
- 开放
Start -> Run -> regedit - 转到
HKEY_LOCAL_MACHINESoftwareMicrosoftCommand ProcessorAutorun(如果不存在，请创建一个字符串值( - 将值更改为
@chcp 65001>nul - 运行
flutter upgrade --force - 在颤振项目文件夹中运行
flutter pub get
如果它不再显示pub get failed，则可以在应用模拟器或物理设备中运行应用。
注意：这可能需要一些时间才能运行您的应用。
最后但并非最不重要的一点是，pub get failed对我来说是一个可怕的错误！
从这里收集的解决方案
单击链接在给定环境中获取包，例如 VS 代码或在打开 pubspec.yaml 文件时保存您的代码将自动为您获取 Flutter 包。
检查 pubspec.yaml 中的语法，它应该看起来像这样
dependencies:
flutter:
sdk: flutter
provider: ^6.0.0
cupertino_icons: ^1.0.2
我所拥有的是这样的，这是不正确的。
dependencies:
flutter:
sdk: flutter
provider: ^6.0.0
cupertino_icons: ^1.0.2
另一件事是检查其他文件中的语法错误，例如缺少 ] 或 (。我遇到了这两个问题，一旦修复，错误就消失了。
在我遇到类似错误的情况下，我在依赖项中指定了intl: 0.18.0。删除它后，一切正常。
1.更新颤振不起作用
2.重新启动电脑将不起作用
3.创建新项目并运行 pub get 将不起作用。
那么唯一的解决方案是暂时使用VPN。有一些网络问题导致了这个问题。
