公司專案使用iview-admin ，當使用npm run build命令打包是報錯。
錯誤提示如下：

問題原因：node 版本問題，node v10 以上 fs.write 的callback 是必須的，降低Node版本可解決。 不安裝node也可以，可以將webpack.dev.config.js 和 webpack.prod.config.js 中的程式碼修改即可：給fs.write新增必要的callback函式，具體操作是修改以上兩個檔案中的以下程式碼：
fs.write(fd, buf, 0, buf.length, 0, function(err, written, buffer) {});修改為：
fs.write(fd, buf, 0, 'utf-8', function(err, written, buffer) {});
重新使用npm run build命令繼續打包即可。
