• 查了两天,最后解决方案:

1. 删掉:下面目录中划红线的配置文件:删掉项目中的node_modules,重新配置npm和yarn,然后执行命令就好了

4. 
      
      
   
        
        
   
         
         
   
        
        
        
        
   
         
         
   
          
          用admin权限执行:
         
         
        
        
   
        
        
   
         
         
   
        
        
        
        
   
         
         
   
          
          npm config 
          
          set registry https:
          
          //registry.npm.taobao.org --global
         
         
        
        
   
        
        
   
         
         
   
        
        
        
        
   
         
         
   
          
          npm config 
          
          set disturl https:
          
          //npm.taobao.org/dist --global
         
         
        
        
   
        
        
   
         
         
   
        
        
        
        
   
         
         
    
         
         
        
        
   
        
        
   
         
         
   
        
        
        
        
   
         
         
   
          
          yarn config 
          
          set registry https:
          
          //registry.npm.taobao.org --global
         
         
        
        
   
        
        
   
         
         
   
        
        
        
        
   
         
         
   
          
          yarn config 
          
          set disturl https:
          
          //npm.taobao.org/dist --global
         
         
        
        
      
      
   

5. 
      
      
   
        
        
   
         
         
   
        
        
        
        
   
         
         
   
          
          按照这个方法安装(先安装node.js,再安装yarn):
         
         
        
        
   
        
        
   
         
         
   
        
        
        
        
   
         
         
    
         
         
        
        
   
        
        
   
         
         
   
        
        
        
        
   
         
         
   
          
          https:/
          
          /yarnpkg.com/zh-Hans/docs/install
          
          #windows-stable
         
         
        
        
   
        
        
   
         
         
   
        
        
        
        
   
         
         
   
          
          https:/
          
          /www.jianshu.com/p
          
          /03a76b2e7e00
         
         
        
        
      
      
   

6. 最后执行: yarn install
