Ghost project, changed the original page style, but did not work

ghost project, modified the original page style, but did not work, I found that the js,css of the ghost project is compressed by grunt, but the command inside pack.json does not have the command to compress the style file, and typing grunt in the root directory is not allowed, what should I do?
