我想在我的命令提示符下运行以下命令 -无法安装从命令提示符蟒蛇 - LXML，libxml2的，libxlst蟒蛇3.4
pip install -r requirements.txt
但我面临着一些，我有问题试图解决，但无济于事。我从命令提示符得到的消息是：
Collecting lxml==3.5.0 (from -r requirements.txt (line 1))
Using cached lxml-3.5.0.tar.gz
Collecting pyquery==1.2.10 (from -r requirements.txt (line 2))
Collecting cssselect>0.7.9 (from pyquery==1.2.10->-r requirements.txt (line 2))
Using cached cssselect-1.0.1-py2.py3-none-any.whl
