IDE cannot install Csv/Config/Decouple import

Using Django Mystery Errors
1

Greetings, i started setting up base.py(settings.py) however when importing these lines

import dj_database_url

from decouple import Csv, config

from unipath import Path

I tried to install via the IDE(PYCharm), as recommended by the debugger itself, but I get errors.

After several attempts, I decided to try to do the same in PowerShell as an admin. Everything was installed there, but in the IDE itself, even after a restart, this problem remains.

This is what is shown in the powershell console.

As you can see, I tried to install them manually, cleared the cache and tried to reinstall, but this did not produce any results, what could be the problem?

I originally got stuck on this because of a runserver bug

versions, which already means that I have them installed…

Decouple 0.0.7 - installed in the root of the project (although I personally didn’t find anything new there)
Setuptools 68.0.0 - similar.
CSV - I haven’t figured out how to install it at all, but this is not so important, because most likely it can be solved faster.
Config 0.5.1
Python - 3.7.9
Unipath 1.1
pathlib2 (aka path) - 2.3.7.post1.
I updated pip - it didn’t help. 24.0 now.

so this is how looks my requirements settings.txt
dj-database-url==0.5.0
Django==3.2.4
psycopg2-binary==2.9.1
python-decouple==3.4
pytz==2021.1
Config==0.5.1
Python==3.7.9
Unipath==1.1
pathlib2==2.3.7.post1
pip==24.0

Are you doing all of this in a virtual environment, or are you trying to do this with the “system-level” installation of Python? If the latter, you really want to use a virtual environment. See How to install Django on Windows | Django documentation | Django

It also looks like you may have conflicting modules here. You show that you may have both decouple and python-decouple installed. It appears that there is a naming conflict involved between the two. You need to remove decouple and reinstall python-decouple.

I’m doing this in a virtual environment, which in turn is located in the env folder in the project root, I tried installing decouple both globally (pip install ) and locally (cd *directory path * > pip install ), however I don’t I cleaned the installation cache after myself, for example, after the global one. However, I did not install them immediately and on different days, because I was busy, the problem is that the global one does not work separately.

The point is, you do not want the package “decouple”. You only want the package “python-decouple”. Do not install “decouple”, and if it is installed, remove it and then reinstall “python-decouple”.

There is a naming conflict between the two, and having both installed is going to cause problems.

It seems like I reinstalled it, but restarting the IDE did not give a good result)

Just changing to a venv directory does not activate it. You need to activate the virtual environment for it to be used. See the docs referenced above.

So, it seems to have worked, only for some reason in another IDE (VSC), but in PYCHARM there is still an error. But let’s skip this point.

Now he’s complaining about directions - (VSC IDE)

The prompt here does not give any indication that the virtual environment is active.

Try running this directly from the command prompt. Let’s make sure you’ve got the environment set up correctly before worrying about integration with an IDE.

Yes, but I did not see that tag in the output you showed at IDE cannot install Csv/Config/Decouple import - #7 by CharonIkh when you tried to run it in VSC.

This error (if redirected correctly) was more-less fixed by adding the pathlib import.

import dj_database_url

from decouple import Csv, config

from unipath import Path

from pathlib import Path

After installing everything necessary in venv and running the debugger, it seems like I didn’t find any errors, if you count
PS E:\TattooFoundlerProject> & e:/TattooFoundlerProject/venv/Scripts/python.exe e:/TattooFoundlerProject/TattooFoundler/TattooFoundler/settings/base.py - like a successful launch.
