python - pip install lxml 在 clang 上提示

Question

我知道有几个非常相似的主题，但每个主题都有独特的 clang 回溯，我的情况也不异常(exception)。

我的 macOS 版本是 Mojave 10.14.2。我安装了命令行工具，$ echo $C_INCLUDE_PATH 输出 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/包括


所以我正在尝试通过 pip install lxml 安装 lxml，并获得以下回溯:

Running setup.py bdist_wheel for lxml ... error

你能帮忙吗？

问题是我试图从我的系统上有 python3.7.0 的 requirements.txt 安装 lxml==3.6.0。 lxml3.6.0与python3.7.0不兼容，请考虑使用lxml>4.0。谢谢@hoefling!
