我在Mac OS X 10.6.2（已安装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......

为什么会抛出此错误的任何建议？

Answer 1

你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，请转到首选项 - ＆gt;下载并选择“命令行工具”。

2.-从https://developer.apple.com/downloads下载“Xcode的命令行工具”.dmg。

您可以使用App Store安装Xcode，但默认情况下不会包含“命令行工具”。

Answer 2

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

Answer 3

嗯，错误消息包括：

您必须安装Apple的开发工具

你呢？它们位于OSX附带的独立XCode磁盘上。

Answer 4

我尝试在安装了XCode的最新Max OSX Lion安装上运行virtualenv时遇到同样的错误消息。

但是：Mark提示on Mar 1 2010：

代码说你还没有安装Xcode，但你说你有。命令行中的install_name_tool说什么？它应该是install_name_tool - ＆gt; install_name_tool == / usr / bin / install_name_tool

我遇到了同样的问题。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

我使用

从/ Developer / usr / bin到/ usr / bin创建了一个simlink

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

输入'which'命令会产生：

 $ 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.

Answer 5

还有一个关于virtualenv的错误10.6见the ticket on virtualenv's bitbucket。即使你解决了问题，你仍然会遇到另一个问题（我认为没有找到Python.framework的图像，但我不记得了 - 当我碰到这个时我没有记录任何笔记）< / p>

我做了一些调查，我希望用Python 2.7解决问题的根源 - 当然人们都知道它，并向CPython提交补丁来修复它。

然而，似乎有些人在10.6.2和virtualenv 1.4.5中取得了不错的成绩......或者不再使用系统Python（macports，build-by-hand）。

Answer 6

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: unable to use virtualenv

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

Answer 7

将install_name_tool添加到您的路径

export PATH = $ PATH：/ Developer / usr / bin

在Mac OS X上运行Virtualenv时出现问题
