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：/sf/answers/4835356081/

简而言之，请按照以下步骤操作：

1. 在您的终端中，在 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。它看起来像这样（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 用 cocoapods 组件的名称替换“X”，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

这个问题出现在 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，只需运行

export LC_ALL=en_US.UTF-8

在你的终端中，错误应该消失。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。
