当出现此错误npm run build的今天，

一切都4天前正确。

今天，当我更新本地的node_modules时，它就发生了。

我认为应该是某包前几天发布的新版本

任何帮助，将不胜感激！

更新

此错误是由上一版本uglify-js@3.5.10引起的，warnings在选项中删除可暂时修复此错误。

    uglifyOptions: {
          compress: {
                warnings: false,
                pure_funcs: ['console.log']
          }
    }

在VUE中切换样式时，边框样式无法正确呈现

在下面查看此演示：

new Vue({
	el: '#app',
  data: {
  	flag: true
  },
  computed: {
  	style() {
      let styleA  = {
          borderBottom: '1px solid red',
          borderRight: '1px solid red'
       };
       
      let styleB = {
        	border: '1px solid green',
          borderRight: '1px solid red'
      }

      return this.flag ? styleA : styleB
     
    }
  },
  methods: {
  	changeStyle() {
    	this.flag = !this.flag;
    }
  }
})
