在 PythonAnywhere 中托管的 python3.7 Telegram Bot 中找不到“dotenv”模块

Question

I am trying to install my TelegramBot based on Aiogram on PythonAnywhere servers. I setup the environment based on python3.7 I installed my dependencies with:

pip install -r requirements.txt --user

I set up the environment and launched it with:

virtualenv env
. env/bin/activate

But once I launch my app this is the result with an error apparently on load_dotenv :

(env) 22:35 ~ $ python3 main.py
Traceback (most recent call last):
  File "main.py", line 4, in <module>
    import dispatcher
  File "lib/dispatcher.py", line 2, in <module>
    from dotenv import load_dotenv
ModuleNotFoundError: No module named 'dotenv'

Any ideas why on PythonAnywhere server the python-dotenv library seems not working properly?

Thanks

Answer 1

This was the correct path to follow:

virtualenv -p python3 env

. env/bin/activate

pip3 install -r requirements.txt

Otherwise there was a confusion also in the python versions.

Answer 2

您需要在激活环境的情况下运行pip install -r requirements.txt

Answer 3

It looks like you're mixing two ways of installing packages. pip install with the --user flag installs packages outside the virtualenv. So you should run

. env/bin/activate
pip3 install -r requirements.txt
python3 main.py

If it still doesn't work, perhaps you don't have dotenv in your requirements.txt file? Try doing

pip3 install dotenv

...and see if that helps.
