在尝试运行yarn ios时，我收到以下错误：

The following build commands failed:

我得到这些错误：

我跑了"；纱线起始"；。我安装了XCode。我做了
sudo gem install cocoapods
pod install
有什么想法吗？Thnx
有必要先安装XCode b4，然后执行所有这些步骤，如：
npx react-native init TikTok
yarn start
yarn ios
我没有安装XCode&在经历了所有这些步骤之后尝试安装它&得到了上面列出的所有错误。
我最终重新开始了&刚刚运行
npx react-native init TikTok
yarn start
yarn ios
在另一个文件夹&它解决了的问题
