How to create virtual env with python3

Question

I am using python 2.7 + virtualenv version 1.10.1 for running myproject projects. Due to some other projects requirement I have to work wit

Python already ships with its builtin "virtualenv" called venv since version 3.3. You no longer need to install or download the virtualenv scripts for Python 3.3+.

https://docs.python.org/3/library/venv.html

Check that your installation provided the pyvenv command that should take care of creating the "virtualenv". Arguments are similar to the classic virtualenv project.

$ pyvenv --help
usage: venv [-h] [--system-site-packages] [--symlinks | --copies] [--clear]
            [--upgrade] [--without-pip]
            ENV_DIR [ENV_DIR ...]

Creates virtual Python environments in one or more target directories.

positional arguments:
  ENV_DIR               A directory to create the environment in.

optional arguments:
  -h, --help            show this help message and exit
  --system-site-packages
                        Give the virtual environment access to the system
                        site-packages dir.
  --symlinks            Try to use symlinks rather than copies, when symlinks
                        are not the default for the platform.
  --copies              Try to use copies rather than symlinks, even when
                        symlinks are the default for the platform.
  --clear               Delete the contents of the environment directory if it
                        already exists, before environment creation.
  --upgrade             Upgrade the environment directory to use this version
                        of Python, assuming Python has been upgraded in-place.
  --without-pip         Skips installing or upgrading pip in the virtual
                        environment (pip is bootstrapped by default)

Once an environment has been created, you may wish to activate it, e.g. by
sourcing an activate script in its bin directory.
