在 MacOS 中安装 REGEX 时编译错误 [重复]

Question

我正在尝试在 macos catalina 上安装 Regex，但出现此错误，我该如何继续？我尝试更新pip、pip3、pipwin、xcode，但都返回相同的错误，当我安装 NLTK 时也会发生同样的情况。

我能够在 ubuntu 虚拟机上安装所有东西，REGEX 和 NLTK，只在 MacO 上我继续出现以下错误：

pip3 install regex

Answer 1

我不是 mac 超级用户，但你可以试试这个并检查它是否有效。

xcode-select --install

如果它说它已经安装尝试：

xcode-select --reset

我认为可能是问题的原因是正在发生的 xcrun 错误。

Answer 2

潜在的错误似乎是：

invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun`

您很可能可以通过安装命令行工具来解决这个问题：

xcode-select --install
