1.我上传了一个附件 发现是版本不一致；我改为一致后
报错如下
重点错误：Uncaught SyntaxError: The requested module '/node_modules/@vue/shared/dist/shared.esm-bundler.js' does not provide an export named 'isMathMLTag' (at vue.runtime.esm.js:6:575)
其次警告：Deprecation Warning [legacy-js-api]: The legacy JS API is deprecated and will be removed in Dart Sass 2.0.0.
