为Web应用程序运行Flutter时，flutter无法解析依存关系。进程以退出代码69结束

Question

我正在试用Flutter For Web技术预览，但当我创建Flutter Web应用程序时，它在解析依赖关系时显示以下消息：

[FlutterForWebDemoApp] pub get
Resolving dependencies...
Git error. Command: git fetch
fatal: not a git repository (or any of the parent directories): .git
exit code 69

下面是项目的pubspec.yaml文件：

name: flutterwebdemo
description: An app built using Flutter for web

environment:
  # You must be using Flutter >=1.5.0 or Dart >=2.3.0
  sdk: '>=2.3.0-dev.0.1 <3.0.0'

dependencies:
  flutter_web: any
  flutter_web_ui: any

dev_dependencies:
  build_runner: ^1.4.0
  build_web_compilers: ^2.0.0
  pedantic: ^1.0.0

dependency_overrides:
  flutter_web:
    git:
      url: https://github.com/flutter/flutter_web
      path: packages/flutter_web
  flutter_web_ui:
    git:
      url: https://github.com/flutter/flutter_web
      path: packages/flutter_web_ui

任何帮助都将受到高度的感谢。谢谢。

我从here下载了Flutter for web master repo，并将包文件夹flutter_web、flutter_web_ui和flutter_web_test中的所有三个文件夹复制到flutter的主包文件夹中，并在pubspec.yaml中设置了该路径，然后一切正常。

以下是更改后的新pubspec.yaml：

name: flutter_for_web

environment:
  # You must be using Flutter >=1.5.0 or Dart >=2.3.0
  sdk: '>=2.3.0-dev.0.1 <3.0.0'

dependencies:
  flutter_web: any
  flutter_web_ui: any

dev_dependencies:
  build_runner: ^1.4.0
  build_web_compilers: ^2.0.0

dependency_overrides:
  flutter_web:
    path: C:\flutter\packages\flutter_web
  flutter_web_ui:
    path: C:\flutter\packages\flutter_web_ui
