在MacOS中安装正则表达式时出现编译错误

Question

我试图在macos catalina上安装Regex，但我遇到了这个错误，我该如何继续？我试图更新pip、pip3、pipwin、xcode，但两者都返回相同的错误，安装NLTK时也会发生相同的情况

我能够在ubuntu虚拟机上安装，并且只在MacOs上安装了所有东西，REGEX和NLTK，我继续下面的错误：

pip3 install regex

Answer 1

我不是mac超级用户，但你可以试试这个，看看它是否有效

xcode-select install

如果它说已经安装了，请尝试：

xcode-select reset

我认为这可能是问题的原因是正在发生的xcrun错误的原因
