python feedparser ImportError：没有名为feedparser的模块
作者：互联网
当我尝试将feedparser库包含到交互式Python环境中时收到错误：
>>>> import feedparser
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named feedparser
这也发生在BeautifulSoup和pydelicious.为什么我收到此错误？
使用OS X 10.8.3,其中包括/usr/bin目录中的以下文件：
$ll python*
-rwxr-xr-x 2 root wheel 58896 Mar 17 20:55 python
-rwxr-xr-x 6 root wheel 925 Nov 16 10:30 python-config

Python的位置：
$which python
/usr/bin/python
Python的版本：
$python -V
Python 2.7.2
这可能是不必要的,但我用Homebrew安装了Python：
$brew install python
哪个安装了这些文件：
$brew list python
/usr/local/Cellar/python/2.7.4/bin/smtpd2.py
/usr/local/Cellar/python/2.7.4/bin/smtpd2.7.py
/usr/local/Cellar/python/2.7.4/bin/smtpd.py
/usr/local/Cellar/python/2.7.4/bin/pythonw2.7
/usr/local/Cellar/python/2.7.4/bin/pythonw2
/usr/local/Cellar/python/2.7.4/bin/pythonw
/usr/local/Cellar/python/2.7.4/bin/python2.7-config
/usr/local/Cellar/python/2.7.4/bin/python2.7
/usr/local/Cellar/python/2.7.4/bin/python2-config
/usr/local/Cellar/python/2.7.4/bin/python2
/usr/local/Cellar/python/2.7.4/bin/python-config
/usr/local/Cellar/python/2.7.4/bin/python
/usr/local/Cellar/python/2.7.4/bin/pydoc2.7
/usr/local/Cellar/python/2.7.4/bin/pydoc2
/usr/local/Cellar/python/2.7.4/bin/pydoc

/usr/local/Cellar/python/2.7.4/bin/2to3
/usr/local/Cellar/python/2.7.4/Build Applet.app/Contents/ (8 files)
/usr/local/Cellar/python/2.7.4/Frameworks/Python.framework/ (4858 files)

/usr/local/Cellar/python/2.7.4/share/man/ (3 files)
/usr/local/Cellar/python/2.7.4/share/python/ (317 files)
然后我安装了feedparser：
$pip install feedparser
这导致了这些文件：
$ll /usr/local/lib/python2.7/site-packages/f*
-rw-r--r-- 1 foobar admin 166583 Apr 24 20:16 /usr/local/lib/python2.7/site-packages/feedparser.py
-rw-r--r-- 1 foobar admin 138040 Apr 24 20:16 /usr/local/lib/python2.7/site-packages/feedparser.pyc
我希望通过使用Homebrew避免这些问题(Homebrew与其他库一起运行良好).我错过了什么？
解决方法:
如果您的Python位于/usr/bin/python,那么您不使用Homebrew构建的Python,而是使用OS X默认的Python. (另请注意输出中的版本号差异.)因此,使用pip安装的任何软件包都将安装到Homebrew空间中,但OS X提供的Python安装不会显示. (OS X不提供pip,所以这就像Homebrew一样.)
您的修复很可能会更新/usr/bin/bin之前/usr/local/bin的路径.
