vue使用xlsx-style报错: this relative module was not found: ./cptable and ./node_modules/xlsx-style

Vue-cli3.0 or above is configured on the vue.config.js file

  chainWebpack(config) {
    
    
        config.externals({
    
     './cptable': 'var cptable' })
  }
  // 或者另外一种写法
  configureWebpack: {
    
    
        externals: {
    
    
          './cptable': 'var cptable'
        },
  }

Lower versions can modify the configuration on the webpack.base.conf.js file

 externals: [{
    
    
         './cptable': 'var cptable' 
  }]
