I've started to use CKeditor for my strapi project. The CKeditor's build from strapi blog was missing some features, i started to build my own using CKeditor's online builder. After downloaded custom file from CKeditor i ran npm install && npm run build. In strapi project I ran npm install --save ./external/ckeditor5-strapi ( I copied to my strapi directory). All needed packages are inside node_modules and package.json
But running npm run build still result in module not found? Am I install local package in a wrong way?
