Python 没有名为lxml.html的模块

在运行OS X 10.9.4时，我尝试使用Scrapy，但出现以下错误：

Traceback (most recent call last):
File "/usr/local/bin/scrapy", line 3, in <module>

您似乎是使用系统版Python安装了

scrapy

在Python的virtualenv版本中安装

lxml

使用以下命令检查您的

pip

引用哪种python：

pip -V

---

如果要在virtualenv中安装

scapy

，需要先卸载

scrapy

。否则，由于路径问题，它将阻止运行virtualenv版本

deactive  # deactive first, to use system version of python/pip
pip uninstall -y scrapy
hash -r   # refresh program location.

我想你是对的，它返回：pip1.5 from/Users/username/.virtualenvs/scraper/lib/python2.7/site-packages（python2.7）如何解决它？@mobius，你想用哪种python？@mobius，如果你想要virtualenv-one，在那里安装

scrapy

，

pip安装scrapy

@mobius，我的意思是（系统版本/virtualenv-version）@mobius，首先从系统范围的版本中卸载

scrapy

<代码>停用；pip卸载-y刮屑；散列-r。

deactive  # deactive first, to use system version of python/pip
pip uninstall -y scrapy
hash -r   # refresh program location.
