    我正在尝试创建一个python2.7环境,但是当我运行 

    $ mkvirtualenv --python=python2.7 venv
$ python

Python 3.6.5 (default, Jun 17 2018, 12:13:06)
[GCC 4.2.1 Compatible Apple LLVM 9.1.0 (clang-902.0.39.2)] on darwin

>>>

    我安装了python3.6。知道上面是什么吗?

    下面是带有绝对路径和详细标志的输出

    --python 不使用 PATH /usr/bin/python 指向),或者必须指定可执行文件的完整路径。但是通过调用,您应该得到“可执行文件xxx(from--python=xxx)不存在”,如: 

    $ mkvirtualenv --python=python3 test
The executable /home/jazg/python3 (from --python=/home/jazg/python3) does not exist


    $ mkvirtualenv --python=/usr/bin/python3 test
Already using interpreter /usr/bin/python3
Using base prefix '/usr'
New python executable in /home/jazg/v/test/bin/python3
Also creating executable in /home/jazg/v/test/bin/python

$ python --version
