Django学习第一天之环境搭建篇

涓滴之水终可磨损大石，不是由于它力量大，而是由于昼夜不舍的滴坠。只有勤奋不懈的努力才能够获得那些技巧，因此，我们可以确切地说：说：不积跬步，无以致千里。——贝多芬

创建虚拟环境命令：

命令	行为
mkvirtualenv +环境名称	创建虚拟环境
deactivate	退出虚拟环境
wokeon + 环境名称	进入到某个虚拟环境中
pip list	查看虚拟环境安装包
pip freeze	详细查看安装包（带版本号）
pip install --upgrade pip	更新pip 命令
pip install django ==1.8.2	安装django（教程中版本）

安装django报错：

Collecting django==1.8.2
  Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7facae9b2f98>: Failed to establish a new connection: [Errno 101] 网络不可达',)': /simple/django/
  Retrying (Retry(total=3, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7facae9b2dd8>: Failed to establish a new connection: [Errno 101] 网络不可达',)': /simple/django/

解决办法：根据提示更新pip命令,#号注释语句。

pip (8.1.2)
pkg-resources (0.0.0)
setuptools (21.0.0)
wheel (0.29.0)
#You are using pip version 8.1.2, however version 18.0 is available.
#You should consider upgrading via the 'pip install --upgrade pip' command.

安装成功：

Installing collected packages: django
Successfully installed django-1.8.2

验证安装成功

(py3) python@ubuntu:~$ pip list
Package       Version
------------- -------
Django        1.8.2  
pip           18.0   
pkg-resources 0.0.0  
setuptools    21.0.0 
wheel         0.29.0 

创建一个项目：

 django-admin startproject  + projectName(项目名)

至此，我们在ubuntu环境下的django环境初步搭建完成，可以进行下一步的开发学习了。
