如果您遇到上述错误，请尝试以下命令安装 6-1.11.0 和 tld-0.9。

$ pip install tld --ignore-installed 六 --user

我在安装 pytest 时遇到了同样的问题...似乎与 mojave osx 有关...我已经通过以下方式修复了它：

酿造更新

sudo 安装程序 -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

brew 重新安装 python@2

升级 python 2.7.16 为我在 Mojave 解决了这个问题，谢谢。
这应该是 MacOs 用户的首选答案
