在學(xué)習(xí)Docker容器與容器云第2版時出現(xiàn)的BUG：
第二章，搭建第一個Hello World程序，運行：

python manage.py makemigrations

時報錯：

錯誤原因：
從1.10后django后patterns被移除了，已經(jīng)沒有這個模塊了。使用 django 1.10 以后的版本需要改用 django.conf.urls.url() 。
錯誤代碼：

from django.conf.urls import patterns,include,url from django.contrib import admin from helloworld.views import hellourlpatterns = patterns('',url(r'^admin/', include(admin.site.urls)),url(r'^helloworld$', hello), )

改正代碼：

from django.conf.urls import url,include from django.contrib import admin from helloworld.views import hellourlpatterns = [url(r'^admin/', include(admin.site.urls)),url(r'^helloworld$', hello), ]

運行效果：

總結(jié)
