Question

当我使用终端输入scrapy时，输出如下：

Traceback (most recent call last):
  File "/usr/local/bin/scrapy", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2797, in <module>
    parse_requirements(__requires__), Environment()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 576, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: lxml

然后我在stackoverflow中搜索了一些关于这个问题的解决方案，那么也许我应该运行sudo easy_install --upgrade lxml和sudo easy_install --upgrade lxml，结果在下面

sudo easy_install --upgrade lxml
Searching for lxml
Reading https://pypi.python.org/simple/lxml/
Best match: lxml 3.5.0

sudo easy_install --upgrade scrapy

但是当我再次进入scrapy时，结果仍然令人失望。

scrapy
Traceback (most recent call last):
  File "/usr/local/bin/scrapy", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2797, in <module>
    parse_requirements(__requires__), Environment()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 576, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: lxml

任何人甚至只是给我一个提示将不胜感激。： - ）

你有没有尝试过：

sudo apt-get install python-lxml

这通常对我有用

mac os：pkg_resources.DistributionNotFound：lxml
