我在我的网站上使用Plyr.js，我需要删除库的 plugins.js 和 captions.js 以减小包大小，正如您在bundle image中看到的那样。
现在我已经试过了import {setup} from 'plyr'，，，import Plyr from "plyr/dist/plyr"。import Plyr from "plyr/src/js/plyr";
前两个对包大小没有影响，第三个给出了这个错误：
/node_modules/plyr/src/js/plyr.js
SyntaxError: C:\VSCode Projects\kasbarg\node_modules\plyr\src\js\plyr.js: Support for the experimental syntax 'classProperties' isn't currently enabled (358:8):

Add @babel/plugin-proposal-class-properties (https://git.io/vb4SL) to the 'plugins' section of your Babel config to enable transformation.
If you want to leave it as-is, add @babel/plugin-syntax-class-properties (https://git.io/vb4yQ) to the 'plugins' section to enable parsing.
