MacOSX : no module named twisted. internet 和 gcc 4.0 下的 Python Scrapy

Question

我是一个python新手，想自学Scrapy，第一步就失败了...我安装好 Scrapy，并按照 http://doc.scrapy.org/en/latest/intro/tutorial.html 上的说明进行操作.

在终端输入“scrapy startproject tutorial”后，它返回

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/2.7/bin/scrapy", line 3, in <module>
    from scrapy.cmdline import execute
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-        packages/scrapy/cmdline.py", line 7, in <module>
    from scrapy.crawler import CrawlerProcess
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-    packages/scrapy/crawler.py", line 3, in <module>
    from twisted.internet import reactor, defer
ImportError: No module named twisted.internet

然后我去下载twisted，它需要gcc-4.0，我没有找到它的下载。我的 python2.7.3 似乎在 gcc4.0.1 上运行，但我不知道哪里出错了...这是我在终端中键入“pip install twisted”后的最后几行(虽然我的 pip 正在运行) :

gcc-4.0 -fno-strict-aliasing -fno-common -dynamic -g -O2 -DNDEBUG -g -O3 -arch i386 -arch x86_64 -I/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c twisted/test/raiser.c -o build/temp.macosx-10.3-intel-2.7/twisted/test/raiser.o

unable to execute gcc-4.0: No such file or directory

error: command 'gcc-4.0' failed with exit status 1

我的 Mac 在 MACOSX 10.7.5 上运行，我从未安装 Xcode。

感谢任何帮助!

我在 OSX 上遇到了 Scrapy 的确切问题。我通过以下方式修复了它:

• 从 App Store 安装 Xcode
• 打开 Xcode
• 转到“首选项”
• 选择“下载”标签
• 安装命令行工具
