虚拟env不会运行 - setuptools pip失败，错误代码为2

Question

我想也许是因为目录中有空格，特别是文件夹“Program Files（x86）”。

有人提出这个错误是在较新的virtualenv版本中的已知错误，但我不知道如何安装旧版本。显然版本1.10.1的作品，但我不知道如何安装它..

我运行Windows 7， PIP 6.0.8， Django的1.7.7， 的virtualenv 12.0.7， 的Python 3.4 0.3

当试图运行的virtualenv env命令出现这种情况..

卸载的Python 3.4和安装了Python 2.7的默认目录 “C：/ Python27”。重新安装pip和virtualenv。

现在，当创建一个virtualenv一切工作正常。我想这是因为目录中的空格！
