Create a new virtual environment that is separate from other Python packages

First create a new directory, named XX,

Python3 Operation $:p ython-m venv ll_env

May not succeed

Method One:

Install Virtual environments using PIP install--user virtualenv under Linux

You may be alerted that PIP is not installed

Install PIP and then operate using sudo apt-get install Python-pip

Pip install--user virtualenv to install the virtual machine

　　No distributions at all found for virtualenv

But I have a problem, so the use of Ubuntu comes with apt to install, sure enough, different system operation commands are different.

sudo apt-get install python-virtualenv

Installation Complete

Method Two:

.....

Installing a standalone virtual machine using the sudo apt-get install python_virtualenv

Create a stand-alone virtual space

Virtualenv ll_env

Activated

Activating the Environment $:source Ll_env/bin/activate (Linux)

(llenv) ...

Ll_env\scripts\activate (under Windows)

Stop using Deactivate

Use Pip install Django in the virtual machine to install Django

Pip Install Django

Use django-admin.py startproject learning_log.

Ls

LS learning_log to enumerate what files were created

Create a project note. Must add

LS to enumerate files (the book says to create files) use dir under Window

Ls

LS Learning_log (Windows has problems, go to Linux)

Now we are ready to run the Web service.

The command line is in the following way: Python manage.py runserver 127.0.0.1:8000
