我想也许是因为目录中有空格，特别是文件夹“Program Files（x86）”。
人们已经建议此错误是较新的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工作，但我不知道如何安装..
我正在运行Windows 7， 点6.0.8， Django 1.7.7， virtualenv 12.0.7， Python 3.4.3
尝试运行virtualenv env命令时会发生这种情况..

答案 0 :(得分：1)
卸载Python 3.4并将Python 2.7安装到默认目录＆＃34; C：/ Python27＆＃34;。重新安装了pip和virtualenv。
现在创建virtualenv时一切正常。我猜这是因为目录中的空格！
