hi i have a question how can run a python script in Batch file
i have a setup file for my flask app and every time should set up some environment variable and run app.py
i create a setup for this but i don't know how run python app and it's not working
my setup.cmd file looks like this:
set app_debug=True
set API_KEY=secret
set SECRET_KEY=development mode
set WTF_CSRF_SECRET_KEY=development mode
set email_password=development mode
set RECAPTCHA_PUBLIC_KEY=secret
set RECAPTCHA_PRIVATE_KEY=secret
./venv/Scripts/activate.bat
python app.py
and it's goes to./venv/Scripts/activate.bat and then stop and don't work
I think you have to “call” an external batch file if you want execution to return your current batch file. So write
call./venv/Scripts/activate.bat
in your batch file.
Consider having a .env
file to store your environment variables.
From your app.py
file you can load those env vars.
Reference: https://towardsdatascience.com/environment-variables-python-aecb9bf01b85
Example:
import os
env_var = os.environ.get('ENV')
if not env_var:
print('ENV environment variable does not exist')
I face the same issue with my flask app virtual enviroment setup.bat script, I resolve this issue using below script.
setup.bat
python -m venv venv
call venv\Scripts\activate.bat
pip install -r requirements.txt
call venv\Scripts\deactivate.bat
where, You can see I have used keyword call
which will call the activate.bat file and keep my virtual environment activated while I am doing my pip install
. Once it is done I have deactivated the virtual environment using the same call
command in the batch file.
