Question

尝试在10.7上使用virutalenv版本1.6.4（最新撰写本文），在Mac应用程序商店安装了带有Xcode 4的Lion，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>

  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

有关如何解决此问题的任何提示......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......

提前感谢！

Answer 1

您需要同时安装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“应用程序”或“启动板”
选择XCode-＆gt;偏好设置，然后选择“下载”标签
单击“命令行工具”选项并安装

Answer 2

你真的安装了Xcode 4吗？从App Store下载它只会为其下载安装程序。然后你需要运行安装程序;您应该找到下载到/Applications的安装程序。运行后，您应该在这里找到install_name_tool：

$ which install_name_tool
/usr/bin/install_name_tool

Answer 3

使用较新版本的virtualenv（至少从1.8.4开始），不再需要从Xcode安装“命令行工具”包。

无法调用install_name_tool
