Answer 1

这似乎是 Cocoapods v 1.11.0 中的一种错误/不兼容问题

为了解决这个问题，我按照以下步骤操作，效果非常好：https://stackoverflow.com/a/69076515/16881741

简单地说，请按照以下步骤操作：

1. 在终端的 ios 文件夹中输入

   gem list --local | grep cocoapods

2. 记下上一个命令的输出是什么。看起来像这样（请忽略各个条目附近的版本，这是我的输出，我已经使用版本 1.10.1）：

cocoapods (1.10.1)
cocoapods-core (1.10.1)
cocoapods-deintegrate (1.0.5)
cocoapods-downloader (1.5.1)
cocoapods-plugins (1.0.0)
cocoapods-search (1.0.1)
cocoapods-trunk (1.6.0)
cocoapods-try (1.2.0)

3. 一一启动命令

   sudo gem uninstall X

   将“X”替换为 cocoapods 组件的名称（不带版本）。 最后你应该得到这个：

sudo gem uninstall cocoapods
sudo gem uninstall cocoapods-core
sudo gem uninstall cocoapods-deintegrate
sudo gem uninstall cocoapods-downloader
sudo gem uninstall cocoapods-plugins
sudo gem uninstall cocoapods-search
sudo gem uninstall cocoapods-trunk
sudo gem uninstall cocoapods-try

确保包含第 n.1 点中列出的所有组件，以避免脏状态

4. 使用命令

   sudo gem install cocoapods -v 1.10.1

   获取正确的版本。

Answer 2

此问题出现在 Cocoapods 1.11.0 中，许多人已经注意到回滚到 1.10.2 修复了该问题。但最初的问题来自于终端中设置的错误区域设置。它必须是基于 UTF-8 的语言环境。

这里的第二个答案为我解决了这个问题。

如前所述，运行即可

export LC_ALL=en_US.UTF-8

在您的终端中，错误应该会消失。考虑将其添加到您的

.zshrc

文件中，以便它在每个会话中自动发生。

Answer 3

打开终端

export LC_ALL=en_US.UTF-8

这将解决您的问题。

Answer 4

尝试使用默认

pod install

terminal

。

Answer 5

这对我有用：

flutter clean,
delete /iOS/Pods,
delete /iOS/Podfile.lock,
flutter build ios.

我的 Mac 版本信息：

   CocoaPods : 1.11.0
        Ruby : ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin20]
    RubyGems : 3.0.3
        Host : macOS 11.5.2 (20G95)
       Xcode : 12.5.1 (12E507)
         Git : git version 2.23.0
Ruby lib dir : /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib
Repositories : trunk - CDN - https://cdn.cocoapods.org/

Answer 6

在 VCode 上运行相同的项目并且成功运行，猜测问题出在我的 Android Studio 上。

Answer 7

升级 Ruby 是解决此问题的另一种方法。
