App Center 上的 Flutter iOS 构建失败并出现错误：“Invalid Podfile file: Generated.xcconfig must exist

Question

我刚刚通过article here 将我的应用设置为在应用中心上构建。

虽然 Android 版本在 App Center 上构建和部署良好，但我在 iOS 构建时遇到错误，如下面的构建输出摘录所示：

==============================================================================
Task         : CocoaPods
Description  : Install CocoaPods dependencies for Swift and Objective-C Cocoa projects

[!] Invalid `Podfile` file: Generated.xcconfig must exist. If you're running pod install manually, make sure flutter pub get is executed first.

 #  -------------------------------------------
 #      unless File.exist?(generated_xcode_build_settings_path)
 >        raise "Generated.xcconfig must exist. If you're running pod install manually, make sure flutter pub get is executed first"
 #      end
 #  -------------------------------------------
##[error]The process '/usr/local/lib/ruby/gems/2.6.0/bin/pod' failed with exit code 1
##[error]The 'pod' command failed with error: The process '/usr/local/lib/ruby/gems/2.6.0/bin/pod' failed with exit code 1
##[section]Finishing: Pod install

我的构建脚本是：

#!/usr/bin/env bash
# Place this script in project/ios/.

# Fail if any command fails.
set -e

# Debug log.
set -x
cd ..

git clone -b beta https://github.com/flutter/flutter.git
export PATH=`pwd`/flutter/bin:$PATH

flutter channel beta
flutter doctor

echo "Installed flutter to `pwd`/flutter"

# Build the app.
flutter build ios --release --no-codesign

我确实添加了错误中提到的flutter pub get，但这并没有什么不同。另外值得注意的是，当我在本地 Xcode 中进行构建时，构建工作正常。我还可以毫无问题地将构建的存档部署到 Testflight。这只是我遇到问题的 App Center 构建过程。

我现在有点迷茫，找不到有关如何解决此问题的任何信息。我也是 CI/CD 的新手，因此感谢您的帮助！

更新

我还尝试将以下内容添加到脚本中，以强制 App Center 运行与本地计算机相同版本的 Cocoapods，但这对错误没有影响。

sudo gem uninstall cocoapods
sudo gem install cocoapods -v 1.9.1
pod setup

Answer 1

我对我的克隆后脚本执行了此操作，并且成功了：

#!/usr/bin/env bash
#Place this script in project/ios/

echo "Uninstalling all CocoaPods versions"
sudo gem uninstall cocoapods --all --executables

COCOAPODS_VER=`sed -n -e 's/^COCOAPODS: \([0-9.]*\)/\1/p' Podfile.lock`

echo "Installing CocoaPods version $COCOAPODS_VER"
sudo gem install cocoapods -v $COCOAPODS_VER

# fail if any command fails
set -e
# debug log
set -x

pod setup

cd ..
git clone -b beta https://github.com/flutter/flutter.git
export PATH=`pwd`/flutter/bin:$PATH

flutter channel master
flutter doctor
flutter pub get

echo "Installed flutter to `pwd`/flutter"

flutter build ios --release --no-codesign

诀窍似乎是将“如果任何命令失败则失败”部分移到重新安装 pod 之后

Answer 2

我有同样的问题。当 appcenter-post-clone.sh 运行失败时会发生这种情况，因此，flutter 未安装并且命令 flutter build ios 未运行以生成 Generated.xcconfig。

要修复它，我只是：

• 删除了appcenter-post-clone 并推送了这个提交
• 在构建部分打开了分支的配置。现在克隆后标签已经消失了。保存它。
• 再次使用 appcenter-post-clone.sh 推送另一个提交。
• 再次配置分支，现在带有克隆后标记。
• 保存并构建。

Answer 3

检查你的 .gitIgnore。由于文件被从 repo 中排除，因此遇到了同样的问题。

添加回来后一切正常。

还要注意项目中为 Flutter 定义的路径。

Answer 4

它现在似乎可以工作了。我认为 App Center 构建过程已经更新。 为了您的信息，我在下面包含了我的最终构建后脚本，以防有用：

#!/usr/bin/env bash
#Place this script in project/ios/

# fail if any command fails
set -e
# debug log
set -x

cd ..
git clone -b beta https://github.com/flutter/flutter.git
export PATH=`pwd`/flutter/bin:$PATH

flutter channel beta
flutter doctor

echo "Installed flutter to `pwd`/flutter"

flutter build ios --release --no-codesign

Answer 5

1- 导航到颤振模块目录 2-做一个颤动的酒吧 ** 还要确保您在稳定频道“Flutter”上

Answer 6

尝试进入IOS文件夹然后pod installor pod update

在终端中
