How to read environment variables from .env file in PyCharm (on Mac)

Introduction

If you use pipenv or dotenv in Python, you can use the .env file of project dir. You can read it and set environment variables. Often, you can control the behavior of your environment by writing the .env file in .gitignore so that you don't commit. I love PyCharm, but I didn't know how to get this .env loaded when running from the IDE. However, I finally found it the other day, so I will write it down.

Setting method

flow

First, open Run Configuration. image.png

Open the ʻEnvFile tab and check ʻEnable EnvFile. image.png

Press + to select .env file. image.png

I think that if you choose this, you're done. However, files that start with . like .env are not displayed in the dialog ... I don't feel that I can get them out even if I operate them properly. So I will devise one. image.png

Ingenuity

I will create a symlink in project_dir.

% ln -s .env dot.env

When you open the previous dialog again, the dot.env file is increasing, so select it.

Then you will be able to add it safely. image.png

The contents are also reflected properly.

After reflecting it in the IDE, you can delete the symlink.

% rm dot.env

at the end

It's less stressful because you don't have to manually set and update it every time. Well, maybe everyone is inconvenient, so I think it will be improved within a year ...
