导入错误：没有名为 'secrets' 的模块 - python manage.py 拉取到数字海洋后不起作用

Question

我正在学习从Django开发到部署的课程
把它拉到Digital Ocean后，其他一切都很顺利。直到
我尝试运行python manage.py help

(env) djangoadmin@ubuntu-1:~/pyapps/btre_project_4$ python manage.py help

我得到了这个错误。

Traceback (most recent call last):

我是一个新手，已经被这个问题困扰了一段时间。我只是想知道是什么可能导致这种情况。

Answer 1

secrets模块已在3.6版中添加到Python中。您的主机正在使用Python 3.5，因此secrets模块不可用。你需要一个Python3.6+的主机，或者一个不依赖秘密模块的Django版本

Answer 2

也有同样的问题，通过指定我安装的python版本来解决。即

$ python3
>>> import secrets
>>> secrets.token_hex(16)
