你可以通过以下方法修复Node.js中的“堆出内存”错误。

Increase the amount of memory allocated to the Node.js process by using the --max-old-space-size flag when starting the application. For example, you can increase the limit to 4GB by running node --max-old-space-size=4096 index.js. Use a memory leak detection tool, such as the Node.js heap dump module, to identify and fix memory leaks in your application. You can also use the node inspector and use chrome://inspect to check memory usage. Optimize your code to reduce the amount of memory needed. This might involve reducing the size of data structures, reusing objects instead of creating new ones, or using more efficient algorithms. Use a garbage collector (GC) algorithm to manage memory automatically. Node.js uses the V8 engine's garbage collector by default, but you can also use other GC algorithms such as the Garbage Collection in Node.js Use a containerization technology like Docker which limits the amount of memory available to the container. Use a process manager like pm2 which allows to automatically restart the node application if it goes out of memory.

我只是想补充一点，在一些系统中，即使使用——max-old-space-size来增加节点内存限制，这也是不够的，而且会出现这样的操作系统错误:

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
Aborted (core dumped)

在这种情况下，可能是因为您达到了每个进程的最大mmap。

可以通过运行命令查看max_map_count

sysctl vm.max_map_count

并通过跑步来增加它

sysctl -w vm.max_map_count=655300

并通过添加这一行来修复它，使其在重新启动后不被重置

vm.max_map_count=655300

在/etc/sysctl.conf文件中。

分析误差的一个很好的方法是用strace运行该过程

strace node --max-old-space-size=128000 my_memory_consuming_process.js

我在AWS Elastic Beanstalk上有这个错误，从t3升级实例类型。micro(免费层)到t3。小修正错误

对于像我这样没有找到解决此错误的合适解决方案的初学者，请检查已安装的节点版本(x32, x64, x86)。我有一个64位CPU，我已经安装了x86节点版本，这导致CALL_AND_RETRY_LAST分配失败- JavaScript堆出内存错误。

我在做AOT角构建时也遇到了类似的问题。听从命令帮助了我。

npm install -g increase-memory-limit
increase-memory-limit

为了防止人们在使用产生大量日志记录的nodejs应用程序时遇到这个问题，一位同事通过将标准输出管道到一个文件来解决这个问题。
