推荐答案

在此处找到答案(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:

create your virtualenv environment within a path without spaces. This is why it is happening:

创建环境时，它会设置一个bin目录.在该bin目录中，所有与环境有关的可执行文件.有些是脚本.如您所知，hashbang用来告诉系统使用什么解释器来运行脚本.您可能经常在脚本顶部看到此信息:

When you create an environment, it sets up a bin directory. In that bin directory are all the executables relating to the environment. Some are scripts. As you may know, hashbangs are used to tell the system what interpreter to use to run the script. You may see this at the top of scripts often:

#!/usr/bin/env python

如果脚本位于/tmp/test.py，则指示系统运行此命令来执行脚本:

If the script is at /tmp/test.py, that tells the system to run this command to execute the script:

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

以您为例，virtualenv正在创建如下脚本:

In your case, virtualenv is creating scripts like this:

#!/tmp/oh no/bin/python

当系统尝试执行该命令时，它将尝试使用参数no/bin/python和/tmp/test.py执行命令/tmp/oh. /tmp/oh不存在，所以失败了

When the system tries to execute that, it will try to execute the command /tmp/oh with the arguments no/bin/python and /tmp/test.py. /tmp/oh does not exist, so it fails
