用淘宝的npm可以，用原生的npm下的包就不行，应该是依赖包的问题，一定要把editor升到^3.0

Sample problem as well. I saw the source from "quill" as follows: *quill/core/selection.js* ``` focus() { if (this.hasFocus()) return; this.root.focus(); this.setRange(this.savedRange); } ```

Nodemon has this problem. Use node instead of nodemon.
