[Django 新手问题求教] Django2.2 使用 django-admin runserver 出现 No module named 'Bill'错误，但是使用 Python manage runserver 没问题。

[littlecrab]

问题

使用 python manage.py runserver 正常启动，使用 django-admin 出错。查看 manage.py 中也是用的'Bill.settings'，参考了 overflow 加了命令的参数还是不行，请教大家到底啥原因，如何解决

错误信息

使用命令

django-admin runserver 8054 --settings="Bill.settings" --pythonpath=.

出现错误

(venv-django2.2) D:\PythonApp\Bill>django-admin runserver 8054 --settings="Bill.settings"  --pythonpath="D:\Program Files\Python\Python36"

[OnlyO]

pythonpath 是你项目根文件夹, 你是不是路径没有添对,注意绝对路径和相对路径.

[littlecrab]

@OnlyO 谢谢! 想当然地以为 pythonpath 是 python 路径，No module 的错误就是 pythonpath 配置错了造成的。pythonpath 设置成项目路径就可以了。

不过现在一直提示找不到 django-admin“d:\program files\python\python36\python.exe: can't open file 'D:\Program Files\Python\Python36\Scripts\django-admin': [Errno 2] No such file or directory” ，环境变量没问题，django-admin runserver 也能打印版本号，找到现在也没找到解决方法，请问这个问题您知道如何解决吗
