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):

Try searching in Google for the relevant error, above.
I can’t seem to run bash <(curl -s https://raw.githubusercontent.com/techAPJ/install-rails/master/mac), and it returns an error sh: syntax error near unexpected token(’`
Were any messages output before the error? You’ve not given any indication whether the script ran at all, or threw an error part-way.
I’m glad this topic was bumped (purely by coincidence). I guess the issue has been around for a while and isn’t limited to Apple Silicon Macs.
I was having the same issue on my M1 iMac following the same guide as you. @blake was awesome and managed to find a workaround for me. 
I was able to get it working on my m1 mac. I’m not exactly sure what the issue is, but this is a work around that you can use.
From the first terminal tab run:
bin/rails server --binding 127.0.0.1From the 2nd terminal tab. Change into this directory inside the discourse directory.
cd app/assets/javascripts/discourseThen run this command:
ember server --proxy http://127.0.0.1:3000Then browse to http://localhost:4200
I’m not sure. You shouldn’t have to use ember server --proxy on m1 macs anymore. The normal way now is to use one terminal tab from inside the root discourse directory and run bin/ember-cli -u. This will run both the rails and the ember server with one command. Can you try that and see if it works?
thank you！！！！！！
