IOS上的Flutter：致命错误：找不到模块“cloud_firestore”

Question

在github和stack上搜索了很长时间的类似错误后，没有一个建议的解决方案帮助我解决了这个错误。

我试了好几样东西（有点乱）：

• 删除IOS派生数据
• 更改firestore包版本
• 振作干净
• RM-RF IOS/Pods
• rm-rf iOS/.symlinks
• rm-rf iOS/flutter/flutter.framework
• rm-rf iOS/flutter/flutter.podspec
• rm-rf iOS/podfile iOS/podfile.lock iOS/pods iOS/runner.xcworkspace
• 吊舱初始化、安装和更新
• 取消评论平台：iOS,'9.0'从podfile（可能没有链接到此问题）

以下是错误：

    ** BUILD FAILED **


Xcode's output:

这是一个非常糟糕和不幸的错误。在试图解决这个问题几个小时后，我终于找到了解决办法。问题是，您的Podfile没有用pubspec.yaml文件更新。我想，你的播客文件几乎是空的：

target 'Runner' do
 use_frameworks!

end

但这是一个大问题。如果尝试:$rm Podfile和$pod init将创建此Podfile。

以下是我的解决方案：

$ pod install

There are 0 dependencies from the Podfile and 0 total pods installed.

现在回到解决方案...

步骤：使用以下代码更新您的Podfile（请删除文件的旧内容）：

 ENV['COCOAPODS_DISABLE_STATS'] = 'true'

 project 'Runner', {

   'Debug' => :debug,
   'Profile' => :release,
   'Release' => :release,
 }

 def flutter_root
   generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
   unless File.exist?(generated_xcode_build_settings_path)
     raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
   end

   File.foreach(generated_xcode_build_settings_path) do |line|
     matches = line.match(/FLUTTER_ROOT\=(.*)/)
     return matches[1].strip if matches
   end
   raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
 end

 require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

 flutter_ios_podfile_setup

 target 'Runner' do
   use_frameworks!
   use_modular_headers!



   flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
 end

 post_install do |installer|
   installer.pods_project.targets.each do |target|
     flutter_additional_ios_build_settings(target)
   end
 end

现在，Podfile正在更新您在podspec.yaml文件中写下的pods。

$ pod install
