在mac osx上安裝virtualenvwrapper 10.7.3

Question

讓我開始說我是編程，mac osx和bash的新手。

我在我的Mac OS X 10.7.3上獲得virtualenvwrapper安裝程序的時間很艱難。 它當然是一個路徑設置問題，但我只是無法正常工作。在.bashrc中

export WORKON_HOME=$HOME/.Apps 
source /usr/local/bin/virtualenvwrapper.sh 

virtualenvwrapper的

設置一些終端輸出：

which easy_install 
/usr/bin/easy_install 

python -V 
Python 2.7.1 

當我運行在終端 「源的.bashrc」 我沒有得到任何輸出。

當我運行在終端mkvirtualenv我得到：

Error [Errno 2] No such file or directory while executing command install_name_tool -change /System/Library/Fram.../Versions/2.7/Python @executable_path/../.Python 1/bin/python

你可能只需要安裝XCode。它應該是免費的（如果大的話）從App Store下載/安裝。

以供將來參考，我強烈建議使用Python開發的軟件包管理器和PIP（而不是使用easy_install）在OS X上我的首選的軟件包管理器是Homebrew，但MacPorts和Fink都還不錯。除此之外，點可以讓你卸載東西，easy_install不能簡單的做。
