How to activate venv in production
I have a backend application based on Node.js. The code is written in JavaScript, except in folder 'scripts', which it is in Python.
I have some external libraries installed (Pandas, Matplotlib, etc.) to execute those scripts, and I used the virtual environment (venv) to use them it correctly.
However, I always need to activate 'source venv/bin/activate' before to execute them (when I am in localhost).
The problem is in production.
Is there a way to let them activate permanently on production? Or other extra software? I hosted these files on a VPS in Hostinger, but in production I got some errors in scripts which has some libraries installed.
This 'activate' might be the problem.
Solution
- In production, you'll be running your application proper with a service manager, such as systemd (that makes sure it stays running). You can direct the service manager to directly use the venv's Python, e.g.,
/home/app/venv/bin/python myapp.py; you don't need theactivatescript. - To have the virtualenv automatically activated for ad hoc use on the production server, you can use a
.bashrcfile, e.g./home/app/.bashrcthat includessource ~/venv/bin/activate.
