Replit Was Unable to Build the Virtual Environment for Python Project

Problem

Replit Was Unable to Build the Virtual Environment for Python Project or the Project Not Giving Results As We Expected.

This Issue Can also happened to Other Online IDEs Also Like Glitch.

Details

Most Online IDE Already Use Virtual Environment By default already. even if you create an virtual environment with python -m venv venv it will not gonna run again in next run like next day and all packages install with pip install -- needs to install again.

The venv by python -m venv venv for replit is not efficient.

First Solution

Replit uses Poetry Virtual Environment By Default for Python Project. Those are given below.

Note These should run under the shell tab not the console tab.

Command With Pip	Command With Poetry
python main.py	poetry run python main.py
pip install package_name	poetry add package_name
pip uninstall package_name	poetry remove package_name
python -m venv venv	poetry init
source venv/bin/activate	poetry shell
python manage.py runserver	poetry run python manage.py runserver

Mostly just add poetry run at first of running script like add this script to runner file of replit.

Click 3 dots in Open Editor of replit and click Show Hidden File and Edit the File Named .replit to given below.

language = "python3"
run = "poetry run python manage.py runserver 0.0.0.0:8000"
# this is for django

Second Solution

Try Installing the alternative virtual environment named pipenv for the installing packages via requirements.txt file.

For Local Environment we add this package like pip install pipenv but for replit online IDE we go into shell tab and then add package by poetry.

poetry add pipenv

# then run below comman to install dependencies from requirements.txt file
pipenv -r requirements.txt

For pipenv Most Commands are already similar you just need to replace the word pip with pipenv.
For Activating Pipenv Virtual Environment type pipenv shell

.replit should have something like below run command.

language = "python3"
run = "pipenv install && pipenv run manage.py runserver 0.0.0.0:8000"
# just like given below but upper will work perfectly.
# run = "pipenv run manage.py runserver 0.0.0.0:8000"

This Commands for mostly running outside virtual environment without activating it directly.

Command With Pip	Command With Pipenv
python main.py	pipenv run python main.py
pip install package_name	pipenv install package_name
python -m venv venv	pipenv init
source venv/bin/activate && pip install -r requirements.txt	pipenv shell && pipenv shell or just pipenv install
python manage.py runserver	pipenv run python manage.py runserver

Conclusion

I Will Suggest You Use Poetry Because It Have Some Features for replit.

• Faster Installing and file runing process ( compared to pipenv ).
• Packages are not deleted after opening the repl again on next day.
• CPU Load was lower Compared to pipenv.
  • I Ran An Package to install dependencies and the package had more than 50 dependencies for debugging home-assistant/core at github.
  • CPU Gone at Overheating but did not cross the line of cpu Usags ( For Me ).

Replit is an online IDE, hosting cloud, collaborative programming environment, and so much more. I've been a user for a while and I really want to voice out what I love about them.

Give a reaction if any one solutions helped you in any way.
Bye 👋.
