    **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][https_www.npmjs.com_package_node-sa] \#用比较新的版本
    
    sass-loader 版本号：[sass-loader - npm][] \#用比较新的版本
