报错信息
error: bundling failed: Error: The 'decorators' plugin requires a 'decoratorsBeforeExport' option, whose value must be a boolean. If you are migrating from Babylon/Babel 6 or want to use the old decorators proposal, you should use the 'decorators-legacy' plugin instead of 'decorators'.
解决办法
cnpm install babel-plugin-transform-decorators-legacy --save-dev cnpm install @babel/plugin-proposal-decorators --save-dev // 修改.babelrc文件 在plugins 中增加下面代码 "plugins": [ ["@babel/plugin-proposal-decorators", { "legacy": true }], ["@babel/plugin-proposal-class-properties", { "loose" : true }] ]
