我一直在关注本教程： https://python-guide.readthedocs.org/en/latest/dev/virtualenvs/
当我在终端输入时：
virtualenv venv
正如预期的那样，我的目录中会弹出一个文件夹，但是没有激活＆＃39;文件。只有python，python2和python2.7
我试过这只是为了找不到命令。
AJs-MacBook-Pro-4:petrarch AJ$ source venv/bin/python2.7
-bash: ????: command not found
抱歉！请帮助这个新手。
当我再次输入virtualenv venv时，我明白了：
AJs-MacBook-Pro-4:petrarch AJ$ virtualenv venv
New python executable in venv/bin/python
