“ git：错误：无法确定'/Applications/…/iPhoneOS13.0.sdk'的真实路径（errno =没有这样的文件或目录）\ n

Question

我试图React-Native init一个新项目，但它告诉我没有CocoaPods，要我安装，如打击：

info Installing required CocoaPods dependencies
? CocoaPods (https://cocoapods.org/) is not installed. It's necessary for iOS pr
oject to run correctly. Do you want to install it? Yes

好吧，我之前已经安装了Cocoapods，但是我输入了Yes，但是失败了：

当我键入pod install pod repo update和其他Pod命令时，总是会收到这样的错误：

我尝试重新安装Cocoapods

sudo gem install cocoapods
Password:
Successfully installed cocoapods-1.8.3
Parsing documentation for cocoapods-1.8.3
Done installing documentation for cocoapods after 3 seconds
1 gem installed

和sudo xcodebuild -license但它不起作用。顺便说一句，我昨天更新了Xcode，不知道是不是原因

版本11.1（11A1027）

任何人都可以帮助我吗？

首先检查是否为restarting XCode helps，或检查XCode Preference Locations tab以确保您引用的是新的更新版本。
