I’m on mac and following this guide: Beginners Guide to Install Discourse on macOS for Development.
Got to this: bundle exec rake db:create db:migrate RAILS_ENV=test bundle exec rake db:create db:migrate and returning this error:
Could not find nokogiri-1.8.5 in any of the source
Run "bundle install" to install missing gems.
I ran bundle install, but midway, it returns an error, shown here:
Sorry. Here’s the error(In text)
An error occurred while installing pg (1.1.3), and Bundler cannot continue.
Make sure that
gem install pg -v '1.1.3' --source 'https://rubygems.org/'succeeds before bundling.
Sounds like you’re having trouble getting pg (postgres) installed. You’ll need to check the specific error logs to see why.
Here’s the log(Which is extremely long and confusing):

Рад, что эта тема была поднята (чисто случайно). Похоже, проблема существует уже давно и не ограничивается только Mac на чипах Apple Silicon.
У меня возникла та же проблема на моём iMac с M1, когда я следовал той же инструкции, что и вы. @blake оказался на высоте и сумел найти для меня обходное решение. 
Мне удалось заставить это работать на моём Mac с M1. Точно не знаю, в чём проблема, но вот обходной путь, который вы можете использовать.
В первой вкладке терминала выполните:
bin/rails server --binding 127.0.0.1Во второй вкладке терминала перейдите в эту директорию внутри директории discourse.
cd app/assets/javascripts/discourseЗатем выполните эту команду:
ember server --proxy http://127.0.0.1:3000Затем откройте в браузере http://localhost:4200
Не уверен. На Mac с чипом M1 больше не нужно использовать ember server --proxy. Сейчас стандартный способ — открыть новую вкладку терминала в корневой директории Discourse и выполнить команду bin/ember-cli -u. Это запустит и Rails, и сервер Ember одной командой. Попробуйте это и посмотрите, поможет ли.
Спасибо!!!
