别人的python的Django代码：
#!/usr/bin/env python
import os
import sys
if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "conf.development.settings")
try:
from django.core.management import execute_from_command_line
except ImportError as exc:
raise ImportError(
"Couldn’t import Django. Are you sure it’s installed and "
"available on your PYTHONPATH environment variable? Did you "
"forget to activate a virtual environment?"
) from exc
execute_from_command_line(sys.argv)
运行
./manage.py migrate
出错：
其中：
之前是：
Python 2.7.10
现在已经切换为：
Python 3.6.4
了，还是出错：
再去换另外一个python 3的解析器：
结果：
问题依旧。
然后想到了：
估计是默认解析器的问题，换成Python3：
➜ NaturlingCmsServer git:(master) ✗ python3 ./manage.py migrate

然后发现是：
（别人少了）项目根目录中，需要创建文件夹logs，然后就可以了：
但是又有其他错误了。
【总结】
此处，由于Mac中默认的解析器是Python2，
用别人的：其自己的Mac默认解析器据说是Python3
导致此处运行：
./manage.py migrate
出错，去改为：
python3 ./manage.py migrate
即可。
