How to install Python requirements with serverless function?

Is it possible to install Python requirements with a serverless function? Or can we only just built in libraries?

I’m trying to import Selenium.

Hi there,

I’ve not tested this with selenium specifically, but you can install your Python requirements using the following approach:

Create a file with the following content inside your functions dir:


set -e

virtualenv virtualenv
source virtualenv/bin/activate
pip install -r requirements.txt

You can take a look at the following repo as an example:

EDIT: As @danmvi mentioned the file needs to be executable:

git update-index --add --chmod=+x
git commit -m 'Make executable'

Hope that this helps!



Hi, @bobbyiliev answer is correct, but only if permissions are changed in your local machine prior to the deploy, if not the deploy will fail as the file cannot be executed by the function runtime.

git update-index --add --chmod=+x
git commit -m 'Make executable'

Hope this helps!
