虚拟环境无法运行 - setuptools pip 失败，错误代码为 2

Question

我想可能是因为目录中有空格，特别是文件夹“Program Files (x86)”。

人们认为这个错误是较新的 virtualenv 版本中的一个已知错误，但我不知道如何安装旧版本。显然版本 1.10.1 有效，但我不知道如何安装它..

我正在运行 Windows 7， 点 6.0.8, Django 1.7.7， 虚拟环境 12.0.7， Python 3.4.3

当尝试运行 virtualenv env 命令时会发生这种情况..

Answer 1

卸载 Python 3.4 并将 Python 2.7 安装到默认目录“C:/Python27”。重新安装了 pip 和 virtualenv。

现在创建 virtualenv 时一切正常。我猜是因为目录中的空格！
