pip給出“ImportError：沒有名為setuptools的模塊”，但我可以在python解釋器中導入setuptools

Question

我正在設置一個新的Mac，我正在哼唱，安裝點和幾個包。 突然之間，我嘗試運行的每個pip命令都會拋出

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

我想我不小心刪除了一個目錄或其他東西，所以我嘗試重新安裝setuptools，遵循本網站上其他答案的建議。 我從這里下載了setuptools egg並像shell腳本一樣運行它。 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

Processing dependencies for setuptools==0.6c11
Finished processing dependencies for setuptools==0.6c11

現在，如果我啟動交互式python會話，我可以import setuptools ，但是pip（和其他命令行腳本）抱怨它沒有安裝。 任何想法為什么Python似乎找到它，但不是其他腳本？

如果它有幫助，這就是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

你的pip似乎與你的Python不一致。 相比：

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

至

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，那么你應該有

/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 。
