python学习笔记--开发与调试环境(4)在windows10上搭建django开发虚拟环境

1 由于windows自带的dos不是很好用，下载git bash，这样可以在windows下敲inux命令

    例如在dos上查看目录里的子目录和文件，用【dir】，而在git bash上用【ls】。

    当然对于其他linux常用命令都是支持的，比如【pwd】【mkdir】【source】

2 下载并安装python3，在安装过程中勾选同时安装pip

安装完以后，可以在git bash下敲入命令查看

wenca@WENCA-N8P9G MINGW64 ~
$ python -V
Python 3.7.3

wenca@WENCA-N8P9G MINGW64 ~
$ pip -V
pip 19.0.3 from c:\program files\python37\lib\site-packages\pip (python 3.7)

wenca@WENCA-N8P9G MINGW64 ~
$ pip list
Package    Version
---------- -------
Django     2.2.4
pip        19.0.3
pytz       2019.2
setuptools 40.8.0
sqlparse   0.3.0
virtualenv 16.7.2

3 开始搭建虚拟环境

3.1 新建一个目录，用于专门存放各个项目虚拟环境

wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python
$ mkdir virtual_environment

wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python
$ ls
virtual_environment/

wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python
$ cd virtual_environment/

wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment

3.2 新建一个特定项目虚拟环境

wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment
$ virtualenv signup_signin
Using base prefix 'c:\\program files\\python37'
New python executable in C:\Users\wenca\Desktop\Python\virtual_environment\signup_signin\Scripts\python.exe
Installing setuptools, pip, wheel...

安装完成后，可以查看虚拟环境下的目录结构

wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment
$ ls signup_signin/
Include/  Lib/  LICENSE.txt  Scripts/  signup_signin/

3.3 进入到虚拟环境

wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment
$ source signup_signin/Scripts/activate

进入虚拟环境后，提示部分变成，最上面以后为【(虚拟环境名)】

(signup_signin)
wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment
$

3.4 安装项目所需要的各种库，例如本文的django项目，需要djano框架库

(signup_signin)
wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment
$ pip install django

安装完以后，可以查看

(signup_signin)
wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment
$ pip list
Package    Version
---------- -------
Django     2.2.4
pip        19.0.3
pytz       2019.2
setuptools 40.8.0
sqlparse   0.3.0
virtualenv 16.7.2

3.5 开始创建django项目

(signup_signin)
wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment
$ cd signup_signin/

(signup_signin)
wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment/signup_signin
$ django-admin startproject signup_signin

完成以后，会在当前路径下新增一个目录signup_signin/，并且里面还有其他子目录和文件

(signup_signin)
wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment/signup_signin
$ ls
Include/  Lib/  LICENSE.txt  Scripts/  signup_signin/
(signup_signin)
wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment/signup_signin
$ ls signup_signin/
db.sqlite3  manage.py*  signup_signin/

3.6 创建app

(signup_signin)
wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment/signup_signin
$ cd signup_signin/

(signup_signin)
wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment/signup_signin/signup_signin

(signup_signin)
wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment/signup_signin/signup_signin
$ python manage.py startapp signup

3.7 运行django框架提供给开发者的web服务器

(signup_signin)
wenca@WENCA-N8P9G MINGW64 ~/Desktop/Python/virtual_environment/signup_signin/signup_signin
$ python manage.py runserver 5000

  此时会弹出日志信息

You have 17 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.
August 12, 2019 - 21:20:23
Django version 2.2.4, using settings 'signup_signin.settings'
Starting development server at http://127.0.0.1:5000/
Quit the server with CTRL-BREAK.

3.8 测试框架是否正常运行

用浏览器打开【http://127.0.0.1:500】链接，结果如下所示，说明一切正常。
