我在向lxml
安装scrapy方面遇到了问题,但后来我发现了一些有关stackoverflow的信息。根据这些信息,我做了一个sudo easy_install lxml
但有一些错误,我认为scrapy得到了安装:
我得出那个判断的理由是我击退了我可以做的事情:
Python 2.7.5 (default, Jul 28 2013, 07:27:04)
[GCC 4.2.1 Compatible Apple LLVM 4.2 (clang-425.0.28)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from scrapy import *
>>>
但是当我尝试scrapy tutorial时,我得到以下错误:
$ scrapy startproject tutorial
Traceback (most recent call last):
File "/usr/local/bin/scrapy", line 4, in <module>
import pkg_resources
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2603, in <module>

needed = self.resolve(parse_requirements(requirements))

raise DistributionNotFound(req) # XXX put more info here
pkg_resources.DistributionNotFound: lxml
答案 0 :(得分:5)
根据thread:
当您使用pip安装某些软件时,Mac上可能会出现此问题 包和easy_install来安装其他包。
尝试:
sudo easy_install --upgrade lxml
sudo easy_install --upgrade scrapy
