无法调用install_name_tool

Question

尝试使用virutalenv版本1.6.4(最新撰写本文)10.7,Lion与是的Xcode 4从mac app store安装,但我收到以下错误消息:

New python executable in SUPENV/bin/python
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 SUPENV/bin/python
Could not call install_name_tool -- you must have Apple's development tools installed
Traceback (most recent call last):
  File "/usr/local/bin/virtualenv", line 8, in <module>
load_entry_point('virtualenv==1.6.4', 'console_scripts', 'virtualenv')()

  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 672, in __init__
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1202, in _execute_child
OSError: [Errno 2] No such file or directory

关于如何解决这个问题的任何提示...我想第一个是检查我的系统上是否存在install_name_tool,然后强制virtualenv使用它...

提前致谢!

您需要安装XCode,运行它,并选择可选的"命令行工具"包,然后安装它们.更详细:

• 从App Store下载XCode
• 从Applications或Launchpad运行下载的XCode二进制文件
• 选择XCode-> Preferences,然后选择"Downloads"选项卡
• 单击"命令行工具"选项并安装它们
