Question

我刚从SnowLeapord升级到Lion，现在无法创建virtualenvs。我知道升级后有新的Python安装，没有站点包，并尝试再次安装pip和virtualenv以及升级到Xcode4但我总是得到这个错误：

~ > virtualenv --distribute env
New python executable in env/bin/python

我是一个unix / python新手，只是无法弄清楚如何使这个工作。有任何想法吗？如果不使用--distribute标记，我会收到此错误：

Answer 1

事实证明，虽然我将Xcode升级到版本4，但它并不会自动安装命令行工具。我跟着这个http://blog.cingusoft.org/mac-osx-lion-virtualenv-and-could-not-call-in。

基本上，安装Xcode，进入首选项，然后下载并安装“命令行工具”。它现在有效。

命令行工具也可以直接从https://developer.apple.com/downloads/index.action#

获得

Answer 2

我还必须升级我的setuptools。

pip install setuptools --upgrade

Answer 3

cd /usr/lib/python2.7
sudo ln -s plat-x86_64-linux-gnu/_sysconfigdata_nd.py .

升级到Lion后如何让virtualenv工作？
