xlsx-style使用中常见问题及解决办法

问题1. Can't resolve './cptable' in 'xxx\node_modules_xlsx

在vue.config.js中引入以下代码

configureWebpack: {
    externals: {
      './cptable': 'var cptable'
    },
  },

问题2. Can't resolve 'fs'

在vue.config.js中引入以下代码

module.exports = defineConfig({
  transpileDependencies: true,
  configureWebpack: {
 
    externals: {
      './cptable': 'var cptable'
    },
    resolve: {
      fallback: {
        fs: false
      }
    },
  }
})

问题3：Can't resolve 'crypto'in D: code-a\LPA2 admin node modules (xlsx-style）

在vue.config.js中引入以下代码

module.exports = defineConfig({
  transpileDependencies: true,
  configureWebpack: {
 
    externals: {
      './cptable': 'var cptable'
    },
    resolve: {
      fallback: {
        fs: false，
        crypto: false,
      }
    },
  }
})

问题4. jszip not a constructor

通过命令安装Webpack 插件
npm i node-polyfill-webpack-plugin -D

在vue.config.js中引入以下代码

const NodePolyfillPlugin = require("node-polyfill-webpack-plugin")
 
module.exports = defineConfig({
  configureWebpack: {
    plugins: [
        new NodePolyfillPlugin()
      ]
    }
})

处理完后vue.config.js整体代码如下

const { defineConfig } = require("@vue/cli-service");
const NodePolyfillPlugin = require("node-polyfill-webpack-plugin")

module.exports = defineConfig({
  transpileDependencies: true,
  lintOnSave: false,
  devServer: {
    port: 8080, 
    host: '0.0.0.0',
    client: {
      webSocketURL: 'ws://0.0.0.0:8080/ws',
    },
    headers: {
      'Access-Control-Allow-Origin': '*',
    },
    proxy: {
      '/':{
        ws: false,
        target:"http://127.0.0.1:3000",
        pathRewrite:{
          "^/":"/"
        }
      }
    }
  },
  configureWebpack: {
      plugins: [
          new NodePolyfillPlugin()
        ],
    externals: {
      './cptable': 'var cptable'
    },
    resolve: {
      fallback: {
        fs: false,
        crypto: false,
      }
    },
  }

});
