Install virtualenv

Pip install virtualenv

Specify the python version to create a virtual environment (generate wxy-virtualenv in the current directory)

Virtualenv-p C:\ Python27\ python.exe wxy-virtualenv

Example: for example, in D:\ VirtualEnvs >

Execute: virtualenv-p D:\ Python35\ python.exe obpy17

By the same token:

D:\ VirtualEnvs > virtualenv-p C:\ Python27\ python.exe ops-portal

D:\ VirtualEnvs > virtualenv-p C:\ Python27\ python.exe-- no-site-packages ops-portal

Add the parameter-- no-site-packages, so that all third-party packages that have been installed in the system's Python environment will not be copied, so we get a "clean" Python runtime environment without any third-party packages.

Enter the virtual environment:

D:\ VirtualEnvs > ops-portal\ Scripts\ activate

(ops-portal) D:\ VirtualEnvs >

Install the software into a specified python or pip environment

Switch to a virtual environment:

(obpy17) D:\ VirtualEnvs\ obpy17\ wxy-packages\ paramiko2.2.1 >

Use pip in a virtual environment:

D:\ VirtualEnvs\ obpy17\ Scripts\ pip.exe install-e git+ https://github.com/paramiko/paramiko/

# egg=paramiko

Use python in a virtual environment:

(obpy17) D:\ VirtualEnvs\ obpy17\ wxy-packages\ paramiko-2.2.1 >

D:\ VirtualEnvs\ obpy17\ Scripts\ python.exe setup.py install
