The python path does not pass in virtualenv.

The environment is ubuntu and python 2.7 is installed.I want to use virtualenv, so
$virtualenv--python=/usr/lib/python 2.7.
I entered , but it says there is no such file.
When I looked at the python path, it appeared as follows:

[', '/usr/lib/python 2.7', '/usr/lib/python 2.7/plat-x86_64-linux-gnu', '/usr/lib/python 2.7/lib-tk', '/usr/lib/python 2.7/lib-old', '/usr/lib-old', '/lib/lib/python 2.7/lib/lib-lively-doubry-doubry-doubry-doubry-doubry-doubry-doubry-doubry-doubry-doubry-doub

I think the pass is correct, but why can't I?

If you use sys.path to find the path of Python, you will see the path to find the module instead of the path of Python interpreter.

To find out the full path of Python interpreters, use which at the terminal.

 which python 2

For python programs, use sys.executable.

import sys
sys.executable

virtualenv uses the --python option to specify the interpreter for Python, but it is possible to specify an absolute path, but if you do not necessarily need an absolute path and want to install python 2.7, you can enter:

virtualenv -- python=python2env

Also, if you have virtualenv installed in python 2.7 (venv is available for Python 3, you can skip the option and enter the following:

virtualenvenv

The official virtualenv documentation describes:

-pPYTHON_EXE, --python=PYTHON_EXE
The Python interpreter to use, e.g., – python= python 2.5 will use the python 2.5 interpreter to create the new environment. The default is the interpreter that virtualenv was installed with (like/usr/bin/python)
