Is this a standard install? A development install?

3

Follow the guide Install Discourse on Ubuntu or Debian for Development

4

You need to have the rails server running.

Or you can use -u to run both.

Consider Developing Discourse using a Dev Container. Say more about what you did. Did you start rails?

Did you do something like:

cd ~/discourse
./bin/rails s

You need to do that in another terminal before running ./bin/ember-cli

Make sure the right version of imagemagick is installed.

Looks like good advice. Here’s how I do that. It assumes you’ve got asdf and docker.

  IMAGE_MAGICK_VERSION=$(docker run discourse/base:release bash -c 'magick --version'|head -1|cut -d' ' -f3)
  echo "Got IMAGE_MAGICK_VERSION: $IMAGE_MAGICK_VERSION"
  asdf install imagemagick $IMAGE_MAGICK_VERSION 2>&1 |grep -v "already"
  echo "installed imagemagic, now set global"
  asdf global imagemagick $IMAGE_MAGICK_VERSION 2>&1 |grep -v "already"
  echo "global done."
