路径问题

位于syl/settings

 

1.1操作系统文件绝对路径

import os
print(os.path.abspath(__file__))                                                               #/root/day/day08/syl/syl/settings.py

print(os.path.dirname(os.path.abspath(__file__)))                                   #/root/day/day08/syl/syl

print(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))       #/root/day/day08/syl

 

STATIC_URL='/static/'

 

 

2导包路径

 

 

import sys
print(sys.path)

['/root/day/day08/syl/syl', '/root/day/day08', '/root/day/day08/celery_task', '/root/day/day08/syl', '/root/day/day08/syl/apps', '/root/day/day08/syl/libs', '/sortware/pycharm/plugins/python/helpers/pycharm_display', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/root/.virtualenvs/syl/lib/python3.6/site-packages', '/sortware/pycharm/plugins/python/helpers/pycharm_matplotlib_backend']

sys.path.insert(0,os.path.join(BASE_DIR,'apps'))

print(sys.path)

['/root/day/day08/syl/apps', '/root/day/day08/syl/syl', '/root/day/day08', '/root/day/day08/celery_task', '/root/day/day08/syl', '/root/day/day08/syl/apps', '/root/day/day08/syl/libs', '/sortware/pycharm/plugins/python/helpers/pycharm_display', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/root/.virtualenvs/syl/lib/python3.6/site-packages', '/sortware/pycharm/plugins/python/helpers/pycharm_matplotlib_backend']
