我在 Mac OS X 10.6.2（安装了 Xcode）和 Python 2.6 上使用 virtualenv-1.4.5。这是我尝试运行 virtualenv 时得到的结果......

有什么建议为什么会抛出这个错误？

您真正需要做的就是安装 Xcode“命令行工具”，有两种方法可以做到：

1.- 如果您已经安装了 Xcode，请转到 Preferences -> Downloads 并选择“Command Line Tools”。

2.- Download the "Command Line Tools for Xcode" .dmg from: https://developer.apple.com/downloads.

You can install Xcode using the App Store, but it will not include the "Command Line Tools" by default.

从 App Store 安装 XCode 以解决问题。我有同样的错误，安装了 XCode，安装后运行它，现在 virtualenv 可以工作了。

好吧，错误消息包括：

您必须安装 Apple 的开发工具

你？它们位于 OSX 附带的单独的 XCode 磁盘上。

我尝试在安装了 XCode 的最新 Max OSX Lion 安装上运行 virtualenv 时遇到相同的错误消息。

但是：标记提示2010 年 3 月 1 日：

好吧，代码说你还没有安装 Xcode，但你说你已经安装了。命令行中的 which install_name_tool 说什么？它应该是 install_name_tool -> install_name_tool == /usr/bin/install_name_tool

我有同样的问题。我在 Lion (10.7.2) 中安装了最新的 Xcode。

 $ locate install_name_tool
 /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/install_name_tool
 /Developer/usr/bin/install_name_tool
 /Developer/usr/share/man/man1/install_name_tool.1

我做了一个从 /Developer/usr/bin 到 /usr/bin 的simlink

 $ sudo ln -s /Developer/usr/bin/install_name_tool /usr/bin/install_name_tool

输入“which”命令产生：

 $ which install_name_tool
 /usr/bin/install_name_tool

之后我做了 virtualenv 魔术

$ virtualenv -p python2.6 myvirtenv
Running virtualenv with interpreter /opt/local/bin/python2.6
New python executable in myvirtenv/bin/python
Installing setuptools............................done.
Installing pip...............done.

10.6 上的 virtualenv 也有一个错误，请参阅virtualenv 的 bitbucket 上的票证。即使你解决了你遇到的问题，你仍然会遇到另一个问题（我认为没有为 Python.framework 找到图像，但我不记得了——当我遇到这个问题时我没有做任何笔记）

我对此进行了一些调查，我希望问题的根源可以通过 Python 2.7 解决——当然人们知道它，并向 CPython 提交了一个补丁来修复它。

但是，似乎有些人在 10.6.2 和 virtualenv 1.4.5 上取得了不错的效果......或者不再使用系统 Python（macports，手工构建）。

使用@gregglind 的virtualenv 分支有一个解决方案。我在这里回答了同样的问题：mac osx：无法使用 virtualenv

git clone https://github.com/gregglind/virtualenv.git
cd virtualenv
git checkout feature/install_name_tool
sudo python setup.py install

将 install_name_tool 添加到您的路径

导出 PATH=$PATH:/开发者/usr/bin
