我如何找出导致 JavaScript 堆内存不足的代码
How do I find out what code is causing JavaScript heap out of memory
我正在尝试 运行 yarn start 但得到这个：

我在这里看到了一些问题，它们似乎都暗示了与 node --max_old_space_size=8048 类似的内容。在大多数情况下，问题突出显示了导致此问题的代码。我不知道这是什么。我如何找出导致问题的原因？我想首先看看那里是否有任何问题，而不是盲目尝试。
项目文件夹中有我的 node_modules 文件夹的副本会不会以任何方式导致此问题？
不久前遇到过这个问题。这对我有帮助
node --max-old-space-size=8048
您尝试过使用 NVM 吗？降级 Node/Typescript 版本可以帮助您。顺便说一句，我使用了 Node v14.15.5。
我有我的 node_modules 文件夹和一个 node_modules_backup。当我删除 node_modules_backup 时，问题就解决了。
