Question

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>
    working_set.require(__requires__)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 666, in require
    needed = self.resolve(parse_requirements(requirements))

    raise DistributionNotFound(req)  # XXX put more info here
pkg_resources.DistributionNotFound: lxml

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

Scrapy：无法创建项目
