Mac OS：pkg_resources.DistributionNotFound：lxml

Question

when i input scrapy using terminal, the output is below:

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 

then i searched some solutions around this problem in stackoverflow, then maybe i should run sudo easy_install --upgrade lxml and sudo easy_install --upgrade lxml , the result are below

sudo easy_install --upgrade lxml

But when i enter scrapy again, the result was still disappointed.

scrapy

    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: lxml

Anyone even just give me a hint would be appreciated. :-)

Answer 1

Did you try:

sudo apt-get install python-lxml

This is what usually works for me
