我在安装scrapy方面时遇到了问题，lxml但后来我发现了一些关于stackoverflow的信息。基于该信息，我做了sudo easy_install lxml一些错误，我认为scrapy得到了安装：

我做出这个判断的原因是我排斥我可以做到以下几点：

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 *
>>>

但是当我尝试做scrapy教程时，我收到以下错误：

$ 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__)

根据这个线程：

当您使用 pip 安装某些软件包并使用 easy_install 安装其他软件包时，Mac 上可能会出现此问题。

尝试：

sudo easy_install --upgrade lxml 
sudo easy_install --upgrade scrapy
