错误:错误安装cocoapods:错误:未能建立gem本地扩展

我试图将cocoapods安装到运行OSX 10.9.1(新Mavericks)的MacBook Pro上，键入gem install cocoapods后，我得到以下错误:

当前回答

如果以上方法都不起作用，那么按照以下步骤进行

sudo xcode-select——switch /Library/Developer/CommandLineTools Sudo gem安装cocoapods

如果你得到这样的错误＇

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /usr/bin directory

执行步骤3

$ sudo gem install -n /usr/local/bin cocoapods . sh

其他回答

我在macOS Catalina上也遇到了同样的问题。尽管使用Homebrew安装可以工作，但我只是好奇为什么gem安装cocoapods会失败，即使这是他们官方文档中首选或提到的安装方法。

我尝试了上面几乎所有的解决方案，可能也有一些其他的，我在谷歌搜索这个问题时发现的。

最后今天我删除了Xcode 12.4，我已经，并重新安装，实际上是出于其他原因。出于好奇，我再次尝试gem install cocoapods，现在它工作了，并安装cocoapods，与官方文档中提到的方式相同。

我有同样的问题，cocoapods没有安装，浪费了3到4个小时来解决这个错误，最后我得到了解决方案，

步骤1:打开终端，运行“brew重装ruby” 终端将指导您如何导出路径第二步:然后运行“sudo gem install cocoapods”

我得到这个错误，必须完全重新安装cocoapods来修复它。最后工作。也许这个解决方案适用于其他任何人。

sudo rm -rf home_folder/.cocoapods/

之后，又做了一次

pod setup

从零开始安装我的库，一切正常。

希望能有所帮助!

打开终端

xcode-select --install
sudo xcodebuild -license accept
curl -L https://get.rvm.io | bash -s stable

关闭及重开终端机

rvm install ruby-2.6

sudo gem install cocoapods
pod install

在android studio上右键单击项目左上角，然后在Xcode中单击Flutter ->打开IOS模块

我的配置中有多个环境，这导致了问题，因为rvm会干扰安装。曾经的红宝石2。检测到X，安装正常。

对于我的环境，我做了以下工作: 1. xcode-select——安装 2. rvm implode(注意-太激烈了-你可能不需要这样做，我对旧的ruby安装没有任何用途，我通过rvm uninstall逐个删除它们，然后使用rvm implode 3.Gem安装cocoapods

这一次，最后一个命令运行正常，没有任何问题。
