在没有空格的路径中创建您的virtualenv环境。这就是为什么它发生的原因：

创建环境时，它会建立一个bin目录。在该bin目录中是与环境有关的所有可执行文件。有些是脚本。如您所知，hashbang用来告诉系统使用什么解释程序来运行脚本。您可能经常在脚本顶部看到此信息：

#!/usr/bin/env python

如果脚本位于/tmp/test.py，则告诉系统运行以下命令来执行脚本：

/usr/bin/env python /tmp/test.py

就您而言，virtualenv正在创建如下脚本：

#!/tmp/oh no/bin/python

当系统尝试执行该命令/tmp/oh时，它将尝试使用参数no/bin/python和来执行命令/tmp/test.py。/tmp/oh不存在，因此失败。
