electron-vue 执行npm run build无法打包 提示 Identifier ‘tasks‘ has already been declared解决方案

1、electron-vue npm run build提示 Identifier ‘tasks’ has already been declared

  

    

     

    
    

     

      const tasks = 
      new 
      Listr(
     
    

    

     

    
    

     

              ^
     
    

    

     

    
    

     
 
     
    

    

     

    
    

     

      SyntaxError: 
      Identifier 
      'tasks' has already been declared

          at 
      Module.
      load (internal/modules/cjs/loader.
      js:
      928:
      32)

      Function.
      Module.
      _load (internal/modules/cjs/loader.
      js:
      769:

          at 
      Function.
      executeUserEntryPoint [
      as runMain] (internal/modules/run_main.
      js:
      72:
      12)
     
    
  

这里错误就是build.js中tasks变量重复声明 

解决办法：

找到 项目根目录 .electron-vue/build.js修改下面代码，修改其中一对的tasks变量名，需要注意的是本文件中一共包含四个tasks，前两个是一对，后两个是一对，修改时请对应修改

 修改完成重新运行 npm run build 又会提示下面错误

2 、electron-vue npm run build提示 ) ReferenceError: Multispinner is not defined

 解决方法： 安装multispinner模块 在.electron-vue\build.js 引入multispinner

解决方法 先安装 Multispinner ，再在文件中引用

cnpm i  multispinner --save
  

注意单词大小写

const Multispinner = require('multispinner')
  

 

修改完成后重新运行 cnpm run build即可完成打包
