# Setting up a dev environment
|
|
|
|
## Prerequisites
|
|
|
|
Mastodon development requires the following:
|
|
|
|
- Ruby 3.0
|
|
- Ruby gems:
|
|
- `bundler`
|
|
- `irb`
|
|
- `foreman`
|
|
- NodeJS v18 (LTS)
|
|
- NPM packages:
|
|
- `yarn`
|
|
- Postgres
|
|
- Redis
|
|
|
|
### macOS
|
|
|
|
First, make sure you have Homebrew installed. Follow the instructions at [brew.sh](https://brew.sh).
|
|
|
|
Run the following to install all necessary packages:
|
|
```
|
|
brew install ruby@3.0 foreman node yarn postgresql redis
|
|
```
|
|
|
|
Ruby 3.0 is **keg-only** by default. Follow the instructions in the **Caveat** to add it to your path.
|
|
|
|
### Linux
|
|
|
|
We will assume that you know how to locate the correct packages for your distro. That said, some distros package `bundler` and `irb` separately. Make sure that you also install these.
|
|
|
|
On Arch, you will need:
|
|
- `ruby`
|
|
- `ruby-bundler`
|
|
- `ruby-irb`
|
|
- `ruby-foreman`
|
|
- `redis`
|
|
- `postgresql`
|
|
- `yarn`
|
|
- `gmp`
|
|
- `libidn`
|
|
|
|
### Windows
|
|
|
|
Unfortunately, none of the authors use Windows. Contributions welcome!

|
## Database
|
|
|
|
In the root of this repository, go through the following script:
|
|
```sh
|
|
# Create a folder for local data
|
|
mkdir -p data
|
|
|
|
# Set up a local database
|
|
pg_ctl -D data/postgres initdb -o '-U mastodon --auth-host=trust'
|
|
|
|
# Use the data/postgres folder for the DB connection unix socket
|
|
#
|
|
# If you don't know what that means, it's just a way for Mastodon to communicate
|
|
# with a database on the same machine efficiently.
|
|
#
|
|
# See: https://manpages.ubuntu.com/manpages/jammy/man7/unix.7.html
|
|
echo 'unix_socket_directories = .' >> data/postgres/postgresql.conf
|
|
|
|
# Start the database
|
|
pg_ctl -D data/postgres start --silent
|
|
```
|
|
|
|
## Redis
|
|
|
|
In the root of this repository, run the following:
|
|
```sh
|
|
# Create a folder for redis data
|
|
mkdir -p data/redis
|
|
|
|
# Start Redis
|
|
redis-server ./redis-dev.conf
|
|
|
|
# [Optional] Stop Redis
|
|
# kill "$(cat ./data/redis/redis-dev.pid)"
|
|
```
|
|
|
|
## Ruby
|
|
|
|
```sh
|
|
export RAILS_ENV=development
|
|
|
|
# Bundle installs all Ruby gems globally by default, which might cause problems.
|
|
bundle config set --local path 'vendor/bundle'
|
|
|
|
# [Apple Silicon] If using macOS on Apple Silicon, run the following:
|
|
# bundle config build.idn-ruby -- --with-idn-dir="$(brew --prefix libidn)"
|
|
|
|
# Install dependencies using bundle (Ruby) and yarn (JS)
|
|
bundle install
|
|
yarn install
|
|
|
|
# Setup the database using the pre-defined Rake task
|
|
#
|
|
# Rake is a command runner for Ruby projects. The `bundle exec` ensures that
|
|
# we use the version of Rake that this project requires.
|
|
bundle exec rake db:setup
|
|
|
|
# [Optional] If that fails, run the following and try again:
|
|
# bundle exec rake db:reset
|
|
```
|
|
|
|
## Running Mastodon
|
|
|
|
1. Run `export RAILS_ENV=development NODE_ENV=development`.
|
|
- Put these in your shell's .rc, or a script you can source if you want to skip this step in the future.
|
|
2. Run `bundle exec rake assets:precompile`.
|
|
- If this explodes, complaining about `Hash`, you'll need to `export NODE_OPTIONS=--openssl-legacy-provider`.
|
|
- After doing this, you will need to run `bundle exec rake assets:clobber` and then re-run `bundle exec rake assets:precompile`.
|
|
3. Run `foreman start`
|

# Updates/Troubleshooting
|
|
|
|
## RubyVM/DebugInspector Issues
|
|
|
|
Still unable to fix. Circumvent by removing `better_errors` and `binding_of_caller` from Gemfile.
|
|
|
|
Happy to troubleshoot with someone better with Ruby than us >_<'/.
|
|
|
|
## Webpack Issues
|
|
|
|
If Webpack compalins about being unable to find some assets or locales:
|
|
|
|
Try:
|
|
1. `rm -rf node_modules`
|
|
2. `yarn install`
|
|
|
|
If this doesn't help, try:
|
|
1. `yarn add webpack`
|
|
2. `git restore package.json yarn.lock`
|
|
3. `yarn install`
|
|
|
|
Then re-run `foreman start`. No. We have no idea why this worked.
