在win7上 python 无法安装 lxml的问题
最近在学习python, 想抓取网页, 使用PyQuery这个模块. 在mac上没问题, 但是在win7下无法安装, 查看错误是因为依赖的lxml无法安装导致的. 弄了好久, 终于解决了.
先贴出错误代码:

1.下载对应操作系统的lxml包
lxml
其他python无法安装的模块也可以使用这种方式安装, 从这个地址也能找到对应的whl
2.安装wheel
pip3 install wheel3. 安装lxml
pip3 install C:\Users\admin\Downloads\lxml-3.6.0-cp35-cp35m-win32.whl
