推荐答案

在没有空格的路径中创建您的 virtualenv 环境.这就是它发生的原因:

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

当您创建环境时，它会设置一个 bin 目录.在那个 bin 目录中是所有与环境相关的可执行文件.有些是脚本.您可能知道，hashbangs 用于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这一点:

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，则告诉系统运行此命令以执行脚本:

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

就您而言，virtualenv 正在创建这样的脚本:

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，它会尝试使用参数 no/bin/python 和 /tmp 执行命令 /tmp/oh/test.py./tmp/oh 不存在，所以失败.

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.
