设置 virtualenv 时出现问题

Question

我正在尝试使用 Python 2.6.5 在 Ubuntu 10.04 上设置 virtualenv，但遇到一些问题。

使用 pip 安装 virtualenv 和 virtualenv 包装器后，我运行命令：virtualenv mysite-env --verbose

我收到以下错误：

    fdst = open(dst, 'wb')
IOError: [Errno 20] Not a directory: 'mysite-env/lib/python2.6/lib-dynload/readline.so'

如果再次运行它，我会收到以下错误：

ERROR: It thinks sys.prefix is u'/usr' (should be '/vagrant/mysite-env')
ERROR: virtualenv is not compatible with this system or executable

任何想法如何解决这个问题？谢谢！
