1.查看pip版本 沒有的話就是沒安裝成功 安裝python的時候一般會自動安裝pip

 

//pip版本 pip -V //對應python2.7pip 9.0.1 from /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)pip3 -V //對應python3.6pip 9.0.1 from /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (python 3.6)

 

2.用pip3/Python3安裝Django，1.11.7是最新穩定版(官網download頁面有 https://www.djangoproject.com/download )
這裡注意用sudo 不然會報錯

sudo pip3 install Django==1.11.7

 

提示 ：

Installing collected packages: DjangoFound existing installation: Django 2.1.dev20171130142844 //之前用github下載安裝的最新版，2.x 版本太高Uninstalling Django-2.1.dev20171130142844:Successfully uninstalled Django-2.1.dev20171130142844 //自動卸載掉之前的版本Successfully installed Django-1.11.7 //安裝成功

 

 

3.測試是否安裝成功

cd /Users/z/PyP/Django

 

4.建立一個服務

sudo django-admin.py startproject testLocalHostcd testLocalHost

 

5.運行服務，因為是用pip3/python3安裝的Django 所以應該用python3來運行

python3 manage.py runserver

 

讓命令列飛一會~

...xxx.....xxxdjango.db.utils.OperationalError: unable to open database file

 

報錯了。

 

6.然後用管理員權限運行：

sudo python3 manage.py runserver

 

列印：

Performing system checks...System check identified no issues (0 silenced).You have 13 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.December 01, 2017 - 08:33:50Django version 1.11.7, using settings ‘testLocalHost.settings‘Starting development server at http://127.0.0.1:8000/Quit the server with CONTROL-C.

 

成功，瀏覽器輸入http://127.0.0.1:8000/可以看到

 

查看Django版本

import djangoprint(django.VERSION)

 

列印：(1, 11, 7, ‘final‘, 0) 說明是1.11.7版本。

查看python3安裝目錄

import sysprint(sys.path)

 

列印xxxxxx /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6 xxxx 即是python3安裝目錄

pip3 安裝目錄：/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/pip

pip 安裝目錄在預設python目錄下

Django安裝目錄(用pip3安裝) ：/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django
