解决方法是package.json文件中做如下配置：
"build-prod": "node --max_old_space_size=5048 ./node_modules/@angular/cli/bin/ng build --prod"
然后打包时执行命令：
npm run build-prod

遇到的问题：项目第一次运行时，没问题不
报错
，然后保存项目，热更新重新加载时，控制台会输出以下信息，导致项目断开，需要重新运行
这就是webpack 运行项目
内存溢出
(Last few

)
安装increase-memory-limit
npm i -g increase-memory-limit
在运行项目，热更新加载项目时就不会在
报错
内存溢出
啦
在package.json中的scripts中添加命令:
“fix-memory-limit”: “cross-env LIMIT=8048 increase-memory-limit”,
执行 npm run fix-memory-limit
以上，重新运行npm run dev，问题解决
setx NODE_OPTIONS --max_old_space_size=10240
cmd 运行 set NODE_OPTIONS=–max_old_space_size=4096
这两个都试过都不行，欲哭无泪。
后来听大佬说要下载
npm install -g increase-memory-limit
然后在项目中运行
increase-memory-limit
后面可能会
报错
不是内部或外部命令，删除依赖重新下载。
set NODE_OPTIONS=--max_old_
现在流行的前端框架，vue，
angular
或者是react它们的核心功能是数据绑定，如下代码。<div id="app">
<p>{{ message }}</p>
</div>
<script>
new Vue({
el: '#app',
data: {
message: 'Hello Vue.js!'
