每当我在桌面上创建一个文件夹并在终端上运行“virtualenv venv”时,一切正常。但是,当我尝试在我的“文档”文件夹中创建一个文件夹并运行“virtualenv venv”时,我在下面收到此错误? 有什么建议吗?
Andrews-MacBook-Pro:Python Virtualenv AndrewParkPhotography$ cd myproject
Andrews-MacBook-Pro:myproject AndrewParkPhotography$ ls
Andrews-MacBook-Pro:myproject AndrewParkPhotography$ virtualenv venv

在这里找到答案(Can't install via pip with Virtualenv)
在没有空格的路径中创建virtualenv环境。这就是它发生的原因:
创建环境时,它会设置bin目录。在该bin目录中是与环境相关的所有可执行文件。有些是脚本。您可能知道,hashbang用于告诉系统使用哪个解释器来运行脚本。您可能经常在脚本的顶部看到这个:
#!/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:
/usr/bin/env python /tmp/test.py
在你的情况下,virtualenv正在创建这样的脚本:
#!/tmp/oh no/bin/python
当系统尝试执行该操作时,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,因此失败
