Is this a [standard install](https://meta.discourse.org/t/142537?silent=true)? A development install?

You need to have the rails server running.
Or you can use `-u` to run both.

Consider [Developing Discourse using a Dev Container](https://meta.discourse.org/t/developing-discourse-using-a-dev-container/336366). Say more about what you did. Did you start rails?

Did you do something like:
```plaintext
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.
```plaintext
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."
```
