.bezierEasingMixin();

Inline JavaScript is not enabled. Is it set in your options?

      in D:\CODE\gdfront\node_modules\iview\src\styles\color\bezierEasing.less (

line 110, column 0)

@ ./src/index.less 4:14-216 14:3-18:5 15:22-224

@ ./src/main.js

解决方法，参考https://github.com/ant-design/ant-motion/issues/44：
找到vue.config.js文件，没有vue.config.js的话新建，添加下面代码：

module.exports = { css: { loaderOptions: { less: { javascriptEnabled: true, } } },}
