在更新到macOS 12.1后，我在mac上也遇到了同样的问题 此外，在mac机器上安装Ruby框架可能会出现错误。

你只需要从mac中完全移除可可荚，然后重新安装cocoapods 然后重新安装项目吊舱

这将解决你的问题

这里是一个图像的所有步骤。请按照它正确，我相信你不会得到任何错误。

从如何安装CocoaPods和设置你的Xcode项目。

首先，检查是否必须安装命令行。

你可以打开Xcode，在菜单中导航到 Xcode→首选项→下载→组件。找到命令行工具并选择安装/更新。

如果你没有找到命令行工具，那么你需要在终端上写这个命令:

xcode-select --install

然后点击安装。

如果你已经安装了命令行工具，你需要选择你的Xcode目录(有时这些类型的问题是由于可用的Xcode版本不同造成的)

遵循这个步骤。

打开终端，执行如下命令: Sudo gem安装cocoapods 输入“admin”密码。这可能需要一段时间。几分钟后，它 将显示绿色信息，如果CocoaPods成功安装在您的 Mac机。 如果你在Xcode 6中出现任何错误，比如开发者路径 失踪。首先在终端运行这个命令: sudo xcode-select -switch /Applications/Xcode6。app(或你的XCodeName.app) 现在你可以用你的Xcode项目设置Pod了。

现在你必须安装吊舱。遵循这个步骤。

打开终端 更改目录到您的Xcode项目根目录(其中您的 ProjectName。放置Xcodeproj文件)。 pod设置:(设置CocoaPods主库) 如果成功，将显示:安装完成(只读访问)。所以, 一切都是你安排的。现在让我们做一些更明显的事情。让我们在Xcode项目中安装库。

现在你必须在你的项目中设置和更新与pod相关的库。

Steps to add-remove-update libraries in pod: Open Terminal Change directory to your Xcode project root directory. If your terminal is already running then there isn't any need to do this, as you are already at the same path. touch pod file open -e podfile (This should open a blank text file) Add your library names in that text file. You can add new names (library name), remove any name or change the version, e.g.: pod ’Facebook-iOS-SDK’ pod ’EGOTableViewPullRefresh’ pod ’JSONKit’ pod ‘MBProgressHUD NOTE: Use the (control + ”) button to add single quote at both end of library name. It should be shown as straight vertical line. Without control button it shall be added as curly single quote which will give error while installation of file. Save and close this text file. Now libraries are set up and you have to install/update it Go to your terminal again and run this command: pod install (to install/update these libraries in pod). You should see output similar to the following: Updating spec repo `master’ \ Installing Facebook-iOS-SDK \ Generating support files

设置完成。

注意:

如果你正确地一步一步地遵循了这整个过程，那么你可以在选择Xcode后直接触发pod更新命令，然后选择你的项目路径。并编写命令荚更新。

你也可以在这里检查命令行工具:

检查这个

gem install -p http://proxy_ip:proxy_port compass

你可能需要添加你的用户名和密码:

gem install -p http://[username]:[password]@proxy_ip:proxy_port compass

检查这个链接，它可能会帮助你。

你可以在macOS中通过Homebrew安装CocoaPods。

首先，打开您的终端，并运行以下代码(如果没有安装Homebrew，则用于安装):

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

然后通过以下命令轻松安装CocoaPods:

brew install cocoapods

如果您想为您的项目第一次安装CocoaPods。

示例:在这里，我们将使用CocoaPods逐步安装“Alamofire”SDK。

步骤1。打开终端，点击命令，然后按Enter键

sudo gem install cocoapods

步骤2。如果它要求，您应该提供系统密码，然后按Enter键

步骤3。使用命令“cd”并给出项目的路径，然后按Enter键

注意:输入“cd”命令，然后空格并拖动项目文件夹到终端。它将采取如下所示的项目路径(这里我的项目名称是:Simple Alamofire)

cd  /Users/ramdhanchoudhary/Documents/Swift\ Workspace/Simple\
Alamofire

步骤4。在你的项目中通过终端通过命令“touch Podfile”并按“Enter”创建一个pod文件

touch Podfile

第5步。然后用终端命令“open Podfile”打开“Podfile”，按“Enter”键

open Podfile

步骤6。现在在打开的pod文件中输入以下代码，然后保存并关闭文件

source 'https://github.com/CocoaPods/Specs.git'
    platform :ios, '10.0'
    use_frameworks!

    target '<Your Target Name>' do
            pod 'Alamofire', '~> 4.0'
    end

步骤7。回到终端键入命令“Pod install”，然后按Enter键。

Pod install

步骤8。等待安装完成100%，大约650+ MB

第9步。这就是它去项目文件夹，并打开下面的文件

<your project name>.xcworkspace

第10步。导入Alamofire类并使用!!

import Alamofire

容器安装

Open terminal and type: sudo gem install cocoapods The Gem will get installed in Ruby inside the System library. Or try on Mac OS X v10.11 (El Capitan), type: sudo gem install -n /usr/local/bin cocoapods If there is an error "activesupport requires Ruby version >= 2.xx", then install latest activesupport first by typing in the terminal. sudo gem install activesupport -v 4.2.6 After installation, there will be a lot of messages. Read them and if no error found, it means the CocoaPods installation is done. Next, you need to setup the CocoaPods master repository. Type in the terminal: pod setup And wait it will download the master repository. The size is very big (370.0 MB in December 2016). So it can be a while. You can track of the download by opening Activity and go to the Network tab and search for "git-remote-https". Alternatively, you can try adding "--verbose" to the command like so: pod setup --verbose Once done, it will output "Setup Complete", and you can create your Xcode project and save it. Then in the terminal, cd to your Xcode project root directory (where your .xcodeproj file resides) and type: pod init Then open your project's podfile by typing in terminal: open -a Xcode Podfile Your Podfile will get open in text mode. Initially there will be some default commands in there. Here is where you add your project's dependencies. For example, in the podfile, type pod 'AFNetworking', '0.9.1' (This line is an example of adding the AFNetworking library to your project.) Other tips: Uncomment platform :ios, '9.0' Uncomment use_frameworks! if you're using Swift When you are done editing the podfile, save it and close Xcode. Then install pods into your project by typing in terminal: pod install or (For m1 chip) arch -x86_64 pod install Depending how many libraries you added to your podfile for your project, the time to complete this varies. Once completed, there will be a message that says "Pod installation complete! There are X dependencies from the Podfile and X total pods installed." Now close your Xcode project. Then locate and open the .xcworkspace Xcode project file and start coding. (You should no longer open the xcodeproj file.)
