    原因

    print "%s.%s.%s" % sys.version_info[:3];

    为python2.x版本的语法,如果本地安装的是python3.x,就会报此错误

    解决方法:

     1. 删除项目中的package-lock.json文件,清除缓存,更新版本号

      #后续步骤运行npm install 命令时会重新生成package-lock.json文件

    rm ./package-lock.json  (如果windows系统,手动删除即可)
    # linux 或windows cmd命令窗口下: npm cache
    clear --force npm install -g npm

     2. 修改package-lock.json中依赖包的版本号

        "node-sass": "4.14.1",
        "npm": "^6.14.5",
      #sass-loader版本为可选项,如果项目很旧,sass-loader版本最好不要改动,否则容易引起项目启动异常 "sass-loader": "8.0.2",
      
      

    npm 版本号: npm -v  命令获取

    node-sass 版本号:https://www.npmjs.com/package/node-sa      #用比较新的版本

    sass-loader 版本号:https://www.npmjs.com/package/sass-loader  #用比较新的版本

    
    

     3 重新运行 npm install 命令,即可成功
