【中文标题】如何修复未在 Flutter 项目中安装的 Cloud Firestore 包？【英文标题】：How to fix cloud firestore package not installing in flutter project? 【发布时间】：2020-11-15 06:37:51 【问题描述】：将 firebase cloud firestore 添加到我的项目依赖包中会使我的应用程序崩溃。当我与 youtube 教程一起编码时，我首先观察到了这个问题。现在，即使创建一个新的 Flutter 项目并添加 Cloud Firestore 依赖包，然后尝试构建该应用程序也无法正常工作。如何解决这个问题？
下面的示例是由flutter构建的应用程序在创建一个新项目时添加了一个cloud firestore依赖包。任何帮助表示赞赏。
Pubspec.yaml
environment:
sdk: ">=2.7.0 <3.0.0"
dependencies:
flutter:
sdk: flutter
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for ios style icons.
cupertino_icons: ^0.1.3
cloud_firestore: ^0.13.7
dev_dependencies:
flutter_test:
sdk: flutter
将 cloud_firestore: ^0.13.7 添加到依赖项。

【问题讨论】：
【参考方案1】：我今天遇到了这个问题，并通过将 git 从 2.31.1 变体降级到 version 2.30.1 (Apple Git-130) 来解决它。查看git --version 的输出。
对于底层 git 问题的简单可重现示例：git clone --verbose https://chromium.googlesource.com/chromium/llvm-project/llvm/lib/Fuzzer
在上面的日志中看到
fatal: unable to access 'https://chromium.googlesource.com/chromium/llvm-project/llvm/lib/Fuzzer/': Failed to connect to chromium.googlesource.com port 443: Operation timed out
fatal: clone of 'https://chromium.googlesource.com/chromium/llvm-project/llvm/lib/Fuzzer' into submodule path '/private/var/folders/wc/4m_4_wzs56v5z7g3z35vylxw0000gn/T/d20200725-9607-d8qy8v/third_party/bloaty/third_party/libFuzzer' failed
Failed to clone 'third_party/libFuzzer'. Retry scheduled
更新：2.31.1 git 版本现在可以在 https://chromium.googlesource.com/chromium/llvm-project/llvm/lib/Fuzzer 的所有者运行 git gc 之后运行
【讨论】：
【参考方案2】：
environment:
sdk: ">=2.7.0 <3.0.0"
dependencies:
flutter:
sdk: flutter
cloud_firestore: ^0.13.7 // move to here
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^0.1.3
dev_dependencies:
flutter_test:
sdk: flutter
或 尝试在您的编辑器中安装 Pubspec Assist 插件，以免出现任何错误。
【讨论】：
【参考方案3】：要使用任何 Flutterfire 插件，还必须包含 firebase_core。
添加
firebase_core: ^0.4.5
到您的依赖项。或在pub.dev 上查找最新版本。
【讨论】：
我尝试这个后仍然遇到同样的问题 也分享你的 podfile 我添加了 podfile 的内容 试试pod install。可能需要一段时间才能完成。
[!] 安装 gRPC-Core 时出错 [!] /usr/local/bin/git -C /var/folders/wc/4m_4_wzs56v5z7g3z35vylxw0000gn/T/d20200726-55744-167qc6f 子模块更新 --init --recursive [!] 自动为目标Runner 分配平台iOS 和版本8.0，因为没有指定平台。请在您的 Podfile 中为此目标指定一个平台。见https://guides.cocoapods.org/syntax/podfile.html#platform。以上是关于如何修复未在 Flutter 项目中安装的 Cloud Firestore 包？的主要内容，如果未能解决你的问题，请参考以下文章
