在学习Docker容器与容器云第2版时出现的BUG：
第二章，搭建第一个Hello World程序，运行：
python manage.py makemigrations
时报错：

错误原因：
从1.10后django后patterns被移除了，已经没有这个模块了。使用 django 1.10 以后的版本需要改用 django.conf.urls.url() 。
错误代码：
from django.conf.urls import patterns,include,urlfrom django.contrib import adminfrom helloworld.views import hellourlpatterns = patterns('',url(r'^admin/', include(admin.site.urls)),url(r'^helloworld$', hello),)
改正代码：
from django.conf.urls import url,includefrom django.contrib import adminfrom helloworld.views import hellourlpatterns = [url(r'^admin/', include(admin.site.urls)),url(r'^helloworld$', hello),]
运行效果：
