在 Mountain Lion 中前 mkvirtualenv 时出错答案

【问题标题】：Error when ex mkvirtualenv in Mountain Lion在 Mountain Lion 中前 mkvirtualenv 时出错
【发布时间】：2012-08-15 03:28:27
【问题描述】：

我有 Mountain Lion，我使用这种方法安装了 virtualenv：

sudo easy_install pip
sudo pip install virtualenv virtualenvwrapper
echo "export WORKON_HOME=$HOME/Envs" >> $BASH_CONFIG_FILE
echo "source /usr/local/bin/virtualenvwrapper.sh" >> $BASH_CONFIG_FILE
source ~/.bashrc

当我尝试使用此命令创建 virtualenv 时出现问题：

mkvirtualenv test

我收到此错误：

【解决方案1】：

你没有安装 setuptools，

从here安装它

如果你从lion升级到mountain lion，python安装由于文件系统的一些变化而被破坏，理想情况下你应该从xcode安装命令行工具，然后从python网站安装python，然后从python网站安装setuptools，然后通过easy_install pip，之后一切都会正常。

【解决方案2】：

问题解决了：

Xcode 4 不会自动安装命令行工具。

基本上，安装 Xcode，进入首选项，然后下载并安装“命令行工具”。现在可以了。
