pip給「ImportError：沒有名爲setuptools的模塊」，但我可以在python解釋器中導入setuptools

Question

我正在安裝一個新的mac，我一直在嗡嗡聲，安裝pip和一些軟件包。當突然，每個PIP命令我嘗試運行會拋出

Exception: 
Traceback (most recent call last): 
    File "/Library/Python/2.6/site-packages/pip-1.2.1-py2.6.egg/pip/basecommand.py", line 107, in main 
    status = self.run(options, args) 
    File "/Library/Python/2.6/site-packages/pip-1.2.1-py2.6.egg/pip/commands/install.py", line 248, in run 
    import setuptools 
ImportError: No module named setuptools 

我算了一下，不小心刪除一個目錄或什麼的，所以我嘗試重新安裝setuptools的，下面的other answers本網站上的意見。我從here下載了setuptools egg，並像shell腳本那樣運行它。得到這個輸出：

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/bin 
Installing easy_install-2.7 script to /Library/Frameworks/Python.framework/Versions/2.7/bin 

Installed /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg 
Processing dependencies for setuptools==0.6c11 
Finished processing dependencies for setuptools==0.6c11 

現在，如果我開始一個交互式的Python會話，我可以import setuptools沒有錯誤，但PIP（和其他命令行腳本）抱怨說，它沒有安裝。任何想法爲什麼Python似乎找到它，但不是其他腳本？

如果有幫助，這是什麼在sys.path：

/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg 
/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip

你pip似乎並沒有要與你的Python協議。比較：

File "/Library/Python/2.6/site-packages/pip-1.2.1-py2.6.egg/pip/basecommand.py", line 107, in main 

到

Installed /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg 

如果python2.7有setuptools的，那麼你應該有

/Library/Frameworks/Python.framework/Versions/2.7/bin/easy_install-2.7 

可用，在這種情況下

easy_install-2.7 pip 

應該給你pip-2.7。
