颤振：发布失败

Question

Flutter 项目向我显示警告 'Packages get' has not been run 以及建议的解决方案，

• 获取依赖项
• 升级依赖项
• 忽略

根据Darky 的建议，在此answer 中继续“获取依赖项”

我试过了，但它显示一个错误：

发布失败

/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）有问题，应该在我的 Flutter 项目中哪里更改？

编辑： pubspec.yaml

Answer 1

为Flutter 项目运行

flutter packages get

代替

pub get packages

Answer 2

在你的 devDependencies 中替换

test: 0.12.30+4 # TRANSITIVE DEPENDENCY 和 test: 0.12.30+3

或者你可以潜在地切换到颤振的主分支。因为你最有可能克隆一个基于flutter的master的项目示例

Answer 3

点击链接获取给定环境中的包，如 VS 代码 要么 在 pubspec.yaml 文件打开时保存您的代码将自动为您获取颤振包。

Answer 4

您来自 Windows 操作系统 仍然无法解决pub get failed (1; no message) exit code 1 问题的人，您可以尝试以下步骤：

1. 打开Start -> Run -> regedit
2. 转到HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\Autorun（如果不存在，则创建一个字符串值）
3. 将值更改为@chcp 65001>nul
4. 运行flutter upgrade --force
5. 在你的 flutter 项目文件夹中运行 flutter pub get

如果它不再显示pub get failed，那么您可以在您的应用模拟器或物理设备中运行您的应用。

注意：这可能需要一些时间来运行您的应用程序。

最后但同样重要的是，pub get failed 对我来说是一个可怕的错误！
