为了不污染代码库，我的项目是线上打包的，之前一直都挺好的，但今天推了一版上去后打包就内存溢出了。

根据网上的一些文章，我尝试限制 node 内存。
export NODE_OPTIONS=--max_old_space_size=2048 && yarn build:ssr
结果并没有用，内存还是溢出了。我本地打包试了一下，node 进程大概占用 3.x G。没办法，我将 2048 改成 1500 试了下，服务器还是无法打包，内存还是耗尽了。难道配置没生效？
万分无奈之下，我只能升级配置，4G 升级到 8G，花了五百多😢。
再次打包，结果还是溢出了？？？
等等，难道配置其实是生效的？毕竟 max_old_space_size 只是限制了老生代内存的大小。于是我把这个数值改成 4096，再次打包，激动人心的等待中……当当，打包好了。
为什么呢？这次发版也没改多少东西啊？然后我在打包输出日志中看到了这个：

嗯……这次……加了 monaco-editor。早知道这样用 cdn 不就好了吗，用 vue-monaco-editor 这个库就可以了啊………………
轻量服务器不支持降级啊，我的钱啊~~~~~~~~~~~
8G 内存空闲 7G，心痛啊~~~~~~
