当我在实现更多组件后运行 polymer 构建时，它会耗尽内存。

如果我们增加 --max-old-space-size 它可能会解决问题!但是如何在构建时设置 --max-old-space-size 呢？
最佳答案
用这个命令解决了，我使用的是 Linux
node --max-old-space-size=2048 /usr/local/bin/polymer build
关于node.js - 在构建大型项目时如何在 polymer 中使用 --max-old-space-size 命令，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46322275/
