查询后了解到是Node中通过JavaScript使用内存时只能使用部分内存（64位系统：1.4 GB，32位系统：0.7 GB），如果前端项目比较大，Webpack编译时就会占用很多的系统资源，一旦超出了V8引擎对Node默认的内存限制大小时，就会产生内存溢出的错误。

方法一：

处理方式是：在package.json中script下添加

  "scripts": {
    "fix-memory-limit": "cross-env LIMIT=2048 increase-memory-limit",
    ...
  },
  "devDependencies": {
    "increase-memory-limit": "^1.0.7",
    "cross-env": "^5.2.0",
    ...
  }

接着执行 npm install cross-env --save–dev(目前这里只能使用npm)
以及 npm install increase-memory-limit --save–dev
如果安装失败则需要先删除掉项目的node_modules包
配置并安装成功后执行npm run fix-memory-limit这句，成功则会出现一下界面

方法二：

V8引擎对内存的使用的默认大小限制是1.4G，可以通过node.js命令设置限制来解决这个问题。修改package.json文件中内容，具体如下。

"serve": "npx --max_old_space_size=6144 vue-cli-service serve",
"build": "npx --max_old_space_size=6144 vue-cli-service build --modern"

修改完成后重启项目

方法三：

1. 打开一个cmd窗口
2. 运行setx NODE_OPTIONS --max_old_space_size=6144
3. 关闭所有cmd窗口及代码编辑器
4. 重新打开cmd并再次运行节点命令（npm命令等）

注意：方法二和方法三中的数字的大小不是固定的，可以按照电脑内存的大小以及项目编译时需要的大小来设置
