How to build my new CSS file for Dawn theme

Hi Guys, I am completely stuck trying to make very tiny changes to the dawn theme and need help.

I have installed gulp, yarn and node. I have then gone to the blog CSS file and made the tiniest change to one of the headings. However, when trying to compile the changes I am failing to make them work.

Here are the instructions I have been following: Dawn/README.md at master · TryGhost/Dawn · GitHub

I change directory to: cd content/themes/Dawn-master

Then I type yarn which runs successfully

However, when I run the next bit yarn dev I get the below errors.

yarn run v1.22.5
warning dawn@1.0.0: The engine "ghost" appears to be invalid.
warning dawn@1.0.0: The engine "ghost-api" appears to be invalid.
$ gulp
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /Users/joemacguffog/my_ghost/content/themes/Dawn-master/node_modules/beeper/index.js
require() of ES modules is not supported.
require() of /Users/joemacguffog/my_ghost/content/themes/Dawn-master/node_modules/beeper/index.js from /Users/joemacguffog/my_ghost/content/themes/Dawn-master/gulpfile.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /Users/joemacguffog/my_ghost/content/themes/Dawn-master/node_modules/beeper/package.json.

I have tried following the instructions in the error, but have been trying for hours and have still failed to make any progress. Please help? :slight_smile:

Required info:

  • Latest version of ghost

  • Running locally hosted on a mac

  • Not sure how you would reproduce other than trying to change the CSS of the dawn theme yourself

Hey @JMacGuff :wave:, could you try again now with the latest copy of Dawn? This was fixed :slightly_smiling_face:

Hey @minimaluminium,

Thanks for the help!! I have now managed to make the change to the CSS I wanted to make :slight_smile:

I do seem to be getting a further error that I have pasted below when running yarn dev.

In response to the error I tried kill -9 PID with the appropriate id, but had no success.

Seeing as its working for me now, I am not worried about it but thought I’d share it

You already have a server listening on 35729
You should stop it and try again.
