当我们配置好静态文件路径时,然后登录后台,后台样式全部丢失了,此时,按照网上解决方案,即执行 
 python manage.py collectstatic
后,
This will overwrite existing files!
Are you sure you want to do this?

Type 'yes' to continue,&nbs***bsp;'no' to cancel: yes
    发现后台报错 静态文件找不到,无法迁移,这说明我们得静态路径配置错误,python manage.py  collectstatic  无法收集,
这时,我们可以在一下两处稍微改动一下即可:
    
STATIC_URL = '/static/'
STATICFILES_DIRS = (os.path.join(BASE_DIR, "/static/"),)
STATIC_ROOT = (os.path.join(BASE_DIR, 'static').replace('\\','/'))
将上面信息改成  
STATIC_URL = 'static/'
STATICFILES_DIRS = (os.path.join(BASE_DIR, "static/"),)
STATIC_ROOT = (os.path.join(BASE_DIR, 'static').replace('\\','/'))
即可进行
 python manage.py collectstatic
命令,然后Type 'yes' to continue, or 'no' to cancel: yes
Found another file with the destination path 'admin/css/changelists.css'. It will be ignored since only the first encountered file is collected. If this is not what you want, make sure every static file has a unique path.

2061 static files copied to '/home/python/Desktop/daima/django/django214/CommunityService/static', 361 unmodified.

表示后台样式已经转移到我们创建得静态文件中了,最后我们在把之前的静态文件配置改回来即可成功!
STATIC_URL = '/static/'
STATICFILES_DIRS = (os.path.join(BASE_DIR, "/static/"),)
STATIC_ROOT = (os.path.join(BASE_DIR, 'static').replace('\\','/'))
此时就可以看到我们的后台美观界面啦!
