這裡報錯顯示的JavaScript 堆記憶體不足，在 Node 中通過 JavaScript 使用記憶體時只能使用部分記憶體（64位系統下約為1.4 GB，32位系統下約為0.7 GB），webpack 編譯時就會佔用很多的系統資源，如果超出了V8對 Node 預設的記憶體限制大小，就出現記憶體溢位問題。V8依然提供了選項讓我們使用更多的記憶體。Node 在啟動時可以傳遞 --max-old-space-size 或 --max-new-space-size 來調整記憶體大小的使用限制。
2、解決方案：
1.開啟angular專案目錄node_modules/.bin
2.分別開啟ng.cmd和ngc.cmd檔案，將最後一行程式碼修改為綠色框框中的內容即可。
3、再次執行ng build就可以成功了呢。
