没有名为“dotenv”的模块 python 3.8

Question

EDIT: Solved, if anyone comes across this python3.8 -m pip install python-dotenv worked for me.

I've tried reinstalling both dotenv and python-dotenv but I'm still getting the same error. I do have the.env file in the same directory as this script.

#bot.py
import os
import discord

from dotenv import load_dotenv
load_dotenv()


token=os.getenv('DISCORD_TOKEN')

client = discord.Client()


@client.event
async def on_ready():
    print(f'{client.user} has connected to Discord!')


client.run(token)

Answer 1

I'm new to Python and just got exact same error. Just changed install command to what I used from a MongoDB tutorial to install PyMongo. It worked like a charm :)

python -m pip install python-dotenv

Answer 2

in your installation manager if it's Ubuntu or Debian try: apt install python3-dotenv

you can also try sudo pip3 install dotenv to install via pip.

Whatever you do remember to include explicitly the missing 3 part.

Debian/Ubuntu have separate packages and as of the present time python means python2 and python3 means python3 in their apt repositories. However, when it comes to your locally installed python binary on your system which python binary it defaults to using may vary depending on what /usr/bin/python is symlinked to on your system. Some systems it's symlinked to something like python2.7 and other's it may be something like python3.5 . Similar issues exist with locally installed pip . Hence, why using the '3' is important when installing or searching for python packages

Answer 3

This will solve just installing via terminal:

pip3 install python-dotenv for python 3.0 versions or pip install python-dotenv for python different than 3.0

Answer 4

If you're using poetry ( https://python-poetry.org ), then...

Be sure you're doing:

$ poetry run SOME_COMMAND
# such as `poetry run pytest`

Instead of just:

$ SOME_COMMAND
# such as `pytest`

My problem (in detail) was...

# Starting with a _contrasting_ example that _unexpectedly worked_..

# A long time ago I did..

$ pip install pytest

# And now, I was doing everything below..

$ poetry add requests

# ..Then I wrote code that has `import requests` in it
# ..Then I wrote some unit test code (to use with pytest) to test the use of `requests`

# ..And NOT knowing I'm supposed to do `poetry run pytest`, I was just doing

$ pytest

# ..And it (oddly) worked, perhaps because maybe `requests` had been installed globally somewhere for me.

# ..But then I did

$ poetry add python-dotenv 

# ..Then I wrote code that had `from dotenv import load_dotenv` in it
# ..Then I wrote some unit test code (to use with pytest) to test the use of `python-dotenv`

# And I got the error I should have gotten..

$ pytest

# ..a bunch of error output, including..
ModuleNotFoundError: No module named 'dotenv'

Thus, the fix was:

# Get rid of the global pytest. Don't want to use that.
# (I think this step is optional, b/c I think `poetry run pytest` below will use the pytest installed via poetry in your virtual env (i.e. I _think_ it will (on it's own) NOT use the globally installed pytest.))
$ pip uninstall pytest

$ poetry add python-dotenv
$ poetry add --dev pytest

$ poetry run pytest

Answer 5

In my case, I was aliasing python to python3 , in my zsh console.

Running a .py file with python3 -i filename.py made it work.

Answer 6

I had the same issue because I was running the installation command locally (in my virtual env).

When running it globally (outside of virtual env) it finally resolved the issue ;)

Answer 7

the below line code to execute in terminal will solve the issue. pip3 install python-dotenv

Answer 8

I had the same issue (Python 3.8.5, dotenv 0.15.0) and was getting ModuleNotFoundError: No module named 'dotenv' in both the console and JupyterLab. All other packages seemed to install via pip with no problems.

I just ran:

pip3 uninstall python-dotenv

pip3 install -U python-dotenv

Answer 9

In my case got this error while running pytest .
Issue got resolved by calling python3 -m pytest <- inside poetry

Answer 10

I had the same problem, and tried everything here, but once I closed out of my terminal windows and reopened them, the library was finally recognized.
