TypeError: issubclass() arg 1 must be a class

Installed the vkbottle module through the console, I import it into the code and an error appears:

from vkbottle import Bot, Message, keyboard_gen, types

Traceback (most recent call last):

I was not able to reproduce it. It installs and imports just fine for me. Is it a specific version of the module?

Try with the virtual environment. https://help.pythonanywhere.com/pages/VirtualenvsExplained

If I use virtual environment, then an error comes out:

File "bot1.py", line 6, in <module> bot = Bot("key") File "/home/zxqb/.virtualenvs/myproject/lib/python3.7/site-packages/vkbottle/framework/bot.py", line 104, in init self.group_id = group_id or self.get_id_by_token(token) File "/home/zxqb/.virtualenvs/myproject/lib/python3.7/site-packages/vkbottle/framework/bot.py", line 178, in get_id_by_token if "error" in response: TypeError: argument of type 'NoneType' is not iterable

That looks like you're not getting a response of some sort, which suggests to me that vkbottle is not using the proxy. Check the vkbottle documentation for how to configure it to use a proxy and see http://help.pythonanywhere.com/pages/403ForbiddenError/ for the details that you need to configure.
