Installing Forem on macOS
Note: MacOS ships with a version of Ruby, needed for various operating systems. To avoid causing an issue with your operating system you should use a version manager for Ruby.
If you don't already have a Ruby version manager, we highly recommend rbenv. This will allow you to have different versions running on a per project basis. The MacOS system version of Ruby will stay intact while giving you the ability to use the version needed for this Forem project. Please follow their installation guide.
With the Ruby version manager, install the Ruby version listed on our badge. (i.e. with rbenv:
rbenv install $(cat .ruby-version))
Note: The repository must be forked and cloned before running the
rbenv install $(cat .ruby-version)command.
Please refer to their installation guide.
Forem requires PostgreSQL version 11 or higher to run.
For additional configuration options, check our PostgreSQL setup guide.
Forem uses ImageMagick to manipulate images on upload.
You can install ImageMagick by issuing the following command:
brew install imagemagick
Forem requires Redis version 6.0 or higher to run.
We recommend using Homebrew:
brew install redis
you can follow the post installation instructions, we recommend using
brew services to start Redis in the background:
brew services start redis
You can test if it's up and running by issuing the following command:
Fork Forem's repository, e.g. https://github.com/forem/forem/fork
Clone your forked repository in one of two ways:
- e.g. with HTTPS:
git clone https://github.com/<your-username>/forem.git
- e.g. with SSH:
git clone firstname.lastname@example.org:<your-username>/forem.git
- e.g. with HTTPS:
Install bundler with
gem install bundler
Set up your environment variables/secrets
Take a look at
.env_sampleto see all the
ENVvariables we use and the fake default provided for any missing keys.
If you use a remote computer as dev env, you need to set
APP_DOMAINvariable to the remote computer's domain name.
The backend guide will show you how to get free API keys for additional services that may be required to run certain parts of the app.
For any key that you wish to enter/replace, follow the steps below.
.envby copying from the provided template (i.e. with bash:
cp .env_sample .env). This is a personal file that is ignored in git.
- Obtain the development variable and apply the key you wish to enter/replace. i.e.:
export CLOUDINARY_API_KEY="SOME_REAL_SECURE_KEY_HERE" export CLOUDINARY_API_SECRET="ANOTHER_REAL_SECURE_KEY_HERE" export CLOUDINARY_CLOUD_NAME="A_CLOUDINARY_NAME"
You do not need "real" keys for basic development. Some features require certain keys, so you may be able to add them as you go.

Solution: Complete the steps outlined in the PostgreSQL setup guide.
rbenv: version '<version number>' is not installed (set by /Path/To/Local/Repository/.ruby-version)
Solution: Run the command
rbenv install <version number>

Solution: Run the following to update
brew update && brew upgrade ruby-build. After that, rerun
rbenv install <version number> and that version will get installed.
== Preparing database == Sorry, you can't use byebug without Readline. To solve this, you need to rebuild Ruby with Readline support.

PG::Error: ERROR: invalid value for parameter "TimeZone": "UTC": SET time zone 'UTC'
Solution: Restart your Postgres.app, or, if you installed PostgreSQL with Homebrew, restart with:
brew services restart postgresql
If that doesn't work, reboot your Mac.
ERROR: Error installing pg: ERROR: Failed to build gem native extension. [...]Can't find the 'libpq-fe.h header*** extconf.rb failed ***
Solution: You may encounter this when installing PostgreSQL with the
Postgres.app. Try restarting the app and reinitializing the database. If that
doesn't work, install PostgreSQL with Homebrew instead:
brew install postgresql
If you encountered any errors that you subsequently resolved, please consider updating this section with your errors and their solutions.
