QUESTION
I've tried many different solutions on the web for this problem, but all have been unsuccessful.
Here's the problem: My app needs to know whether it is being run on Heroku (production mode) or locally (development mode). For this purpose, we want to use environment variables. I've understood that environment variables on Heroku can be set in a .env
file. So my attempt was to run heroku run bash -a
and then to install vim by doing this:
ANSWER
Answered 2018-Apr-19 at 11:43There is no need for an .env
file on Heroku. In fact, such a file won't work very well since
- Heroku gets all of its files from your Git repository,
- has an ephemeral filesystem, meaning that changes to files like
.env
will be quickly lost, and - the
.env
file won't be available on other dynos if you scale your app
As such, creating an .env
file on Heroku isn't a good approach.
Instead, you can use its built-in support for environment variables, using heroku config:set
or its web UI. Either way, you'll get a regular environment variable.

On a UNIX-like operating system, using your system’s package manager is easiest. However, the packaged Ruby version may not be the newest one. There is also an installer for Windows. Managers help you to switch between multiple Ruby versions on your system. Installers can be used to install a specific or multiple Ruby versions. Please refer ruby-lang.org for more information.
