【问题描述】：
我知道这个问题被问了很多次。我已经尝试了所有已知的食谱，但仍然有问题。
所以，我创造了清晰的环境。然后pip install lxml报错：

我应该说我已经在 Python3 环境中成功安装了lxml。此外，我之前已经成功将lxml 包安装到其他环境。但现在出了点问题。
任何想法如何用 Python2.7 解决它？
这是折磨的第二天，我要重新安装我的 Ubuntu。
解决方案
Padraic Cunningham 解决了我的问题。日志直接表明问题是系统中没有文件pyconfig.h引起的。它是python-dev 包的文件。但是，这个包已经安装了。因此，很自然地假设该软件包已损坏，应使用sudo apt-get install --reinstall python-dev libpython2.7-dev 重新安装。此外，libpython2.7-dev 已重新安装。在该文件pyconfig.h 出现在正确位置之后，pip install lxlm 成功安装了lxml 包。
【问题讨论】：
-
确保您已安装
python-dev -
那么
ls /usr/include/python2.7/ | grep pyconfig会返回一些东西吗？ -
是的，它应该在那里，只是为了验证
sudo apt-get install libpython2.7-dev -
omg... 我想，我知道是什么导致了问题。两周前，我试图删除所有
*.pyc文件。我想，我还删除了名称中包含pyc的文件，pyconfig就是其中之一。 -
试试
sudo apt-get --reinstall install python-dev libpython2.7-dev
