Ie11 error reporting details

Analysis

Through finding the problem, it is found that the problem occurs in the crypto JS package. Because this error is reported only in ie, the page cannot be loaded. It is thought that the syntax in this package is ie incompatible

Solution:

Let this package be Babel translated

chainWebpack(config) {
    // For IE compatibility, the js under crypto-js and some node_modules have to be babel-translated
    config.module
      .rule('js')
      .exclude.clear().end()
      .include
      .add(resolve('src'))
      .add(resolve('node_modules/@quanzhiFE/qz-frontend-biz/src'))
      .add(resolve('node_modules/element-ui/lib'))
      .add(resolve('node_modules/crypto-js'))
      .end()

  }
