如何轻松安装以将模块安装到正确的目录？

Question

我正在尝试用easy_install安装一个新模块。

当我运行类似于

sudo easy_install foo

foo安装到~/Library/Python/2.7/site-packages/。

这似乎是错误的，因为我不能使用python shell中安装的任何模块。

根据我在阅读了一些与easy_install问题相关的SO文章后的理解，正确的目录应该是/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages ，因为我的python shell使用了/usr/local/bin/python，它象征性地链接到所述目录。

如何告诉easy_install使用此目录而不是当前目录？

谢谢你

编辑：我使用-d /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages选项重新运行setuptools安装。结果如下：

Processing setuptools-0.6c11-py2.7.egg
Removing /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg
Copying setuptools-0.6c11-py2.7.egg to /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
setuptools 0.6c11 is already the active version in easy-install.pth
Installing easy_install script to /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
Installing easy_install-2.7 script to /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages

例如sudo easy_install mechanize的输出是

Searching for mechanize
Best match: mechanize 0.2.5
Processing mechanize-0.2.5-py2.7.egg
mechanize 0.2.5 is already the active version in easy-install.pth

Using /Users/julian/Library/Python/2.7/site-packages/mechanize-0.2.5-py2.7.egg

似乎easy_install仍然使用错误的目录？！非常感谢你的帮助。谢谢您。

一种方法是为您尝试使用的python安装安装setuptools（安装简单）。因此，使用符号链接的python，遵循these instructions，然后使用/Library/Frameworks/Python.framework/Versions/2.7/Scripts中的easy_install，而不是~/Library/Python/2.7/Scripts
