Question

已在原始帖子下方更新并显示错误消息。

原始帖子： 我有一个带有以下Podfile的Swift项目。在项目文件夹中运行“ pod install”不会创建.xcworkspace文件，也不会安装任何Pod。

我遵循了https://cocoapods.org“入门”部分中的所有说明，但仍然没有。

我在做什么错？在最新版本的macOS Big Sur Public Beta上运行Xcode 12.1。

target 'FY' do
use_frameworks!
pod 'Firebase/Core'
pod 'Firebase/Messaging'
pod 'FacebookCore'
pod 'FacebookLogin'
end

更新并显示错误消息： 显然，由于/ usr / bin问题，未安装Cocoapods。我使用sudo gem install cocoapods --verbose来获取以下错误消息。还从开发人员门户网站安装了Xcode 12.1和12.2的命令行工具。

初始化cocoapods

第一次需要在项目目录中运行pod init来初始化项目。

它将创建新的xcworkspace AND pod文件。完成此操作后，将您的Pod添加到Pod文件中并运行pod install

确保xcode项目的部署目标与pod文件中的平台相同。例如ios 14.1。

安装广告连播

如果要添加更多Pod，请将其添加到Pod文件中，然后在项目目录中再次运行pod install。

更新广告连播

如果要更新所有Pod，请在项目目录中运行pod update。

从项目中删除单个吊舱

只需从pod文件中删除该行或对其进行注释，然后再次在您的项目目录中运行pod install。

从项目中删除可可足类

在某些情况下，可能有必要从项目中完全删除可可足类。在项目目录中运行以下命令。

pod deintegrate

pod cache clean --all

rm Podfile

如果仅尝试重新安装它，请仅尝试pod deintegrate，并保持Pod文件和高速缓存不变。后跟pod install。如果这样做不起作用，请使用上面的所有三个命令并从头开始。

如果尚未安装pod deintegrate和pod clean，则可能需要安装。运行sudo gem install cocoapods-deintegrate cocoapods-clean。

安装说明

确保在您的系统上正确安装了cocoapods。您可以使用pod --version，它将为您提供已安装的版本。如果显示“找不到文件或类似文件”，则说明有问题。

sudo gem install cocoapods通常具有usr/bin目录权限的问题。它应该告诉您在尝试安装时。

改为尝试sudo gem install -n /usr/local/bin cocoapods。

如果这不起作用，请尝试sudo gem install cocoapods --verbose并查看输出。通常在最后，您会看到导致安装失败的错误。

使用安装cocoapods时使用的相同命令将其更新到最新版本。
