公司项目使用iview-admin ，当使用npm run build命令打包是报错。

错误提示如下：

❯ npm run dev
    
    > iview-admin@1.3.1 dev /Users/xiaoyue/myProject
    > webpack-dev-server --content-base ./ --open --inline --hot --compress --config build/webpack.dev.config.js

问题原因：node 版本问题，node v10 以上 fs.write 的callback 是必须的，降低Node版本可解决。  
不安装node也可以，可以将webpack.dev.config.js 和 webpack.prod.config.js 中的代码修改即可：给fs.write添加必要的callback函数，具体操作是修改以上两个文件中的以下代码：

fs.write(fd, buf, 0, buf.length, 0, function(err, written, buffer) {});

修改为：

fs.write(fd, buf, 0, 'utf-8', function(err, written, buffer) {});

重新使用npm run build命令继续打包即可。
