上面的问题是没有配置upload-adapter

解决方法

不要用ckeditor5-vue 里面的ckeditor5-editor-classic，重新打包ckeditor5-editor-classic， 引入SimpleUploadAdapter

自行打包

1. github 下载源码 ceeditor5
2. cd ckeditor5/packages/ckeditor5-build-classic 修改src/ckeditor.js

cd ckeditor5/packages/ckeditor5-build-classic
npm run build

4. 复制ckeditor5/packages/ckeditor5-build-classic/build所有文件到项目目录下替换
