Question

我知道这个问题被多次询问过。我尝试了所有已知的食谱，但仍有问题。

所以，我创造了清晰的环境。然后pip install lxml出错：

我应该说我已经使用Python3成功地在环境中安装了lxml。此外，我已经成功地将lxml包安装到其他环境中。但现在有些事情破裂了。

如何用Python2.7解决它？

这是折磨的第二天，我即将重新安装我的Ubuntu。

解

Padraic Cunningham 解决了我的问题。日志直接表示问题是由系统中缺少文件pyconfig.h引起的。它是python-dev包的文件。但是，此软件包已安装。因此，自然会假设软件包已损坏，应使用sudo apt-get install --reinstall python-dev libpython2.7-dev重新安装。此外，重新安装了libpython2.7-dev。在该文件pyconfig.h出现在正确的位置并且pip install lxlm成功安装了lxml包之后。

你可以尝试一下：

sudo apt-get install python-dev libxml2-dev libxslt1-dev zlib1g-dev

pip install lxml错误
