mac osx:无法使用virtualen

Question

我正在尝试使用virtualenv创建一个环境。在

virtualenv test
New python executable in test/bin/python
Error [Errno 2] No such file or directory while executing command install_name_tool -change /System/Library/Fram.../Versions/2.6/Python @executable_path/../.Python test/bin/python
Could not call install_name_tool -- you must have Apple's development tools installed
Traceback (most recent call last):

文件夹创建正常，但缺少activate之类的文件。有人吗？（我安装了xcode 3.2.3。运行Python2.6、osx 10.6.8）

Answer 1

在安装了XCode并使用appstore的最新maxosxlion（10.7.2）安装上运行virtualenv时，我也收到了同样的错误消息。在

我也错过了/usr/bin/install_name_工具，但是它在系统中。使用以下代码块中的端子。在

 $ 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

我用一个simlink从/Developer/usr/bin到/usr/bin

^{pr2}$

输入“which”命令将生成：

 $ which install_name_tool
 /usr/bin/install_name_tool

在那之后我做了虚拟魔术

$ 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.

现在工作起来很有魅力！在

Answer 2

使用@gregglind's fork of virtualenv中的install_name_工具：

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

Answer 3

开发人员工具安装不正确。我建议安装Xcode 4。在
