节点--max_old_space_size不起作用 [英] node --max_old_space_size is not working

问题描述

节点版本:6.9.x

Node Version: 6.9.x

我的应用程序给了我FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory错误.

My application was giving me FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory error.

所以我尝试使用max_old_space_size标志更改内存分配

So I tried changing the memory allocation using max_old_space_size flag

在执行server.js时，我给出了--max_old_space_size=4096参数.

While executing my server.js, I am giving the --max_old_space_size=4096 argument.

但是，它不断崩溃，并返回与以前相同的错误.另外，我注意到崩溃时抛出的错误中的数字.看起来它仍然是默认的1.4 GB分配空间.

However, it keeps crashing with same error as before. Also, I noticed the numbers in the error thrown while crashing. Looks like its still the default allocation of 1.4 GB.

这是我的错误消息:

在最后几个GC"部分中，提到的内存大小始终约为1404 MB.我在做什么错了?

In the "Last few GCs" section, the memory size mentioned is always around 1404 MB. What am I doing wrong?

系统是否无法分配更多的内存?

Is the system not able to allocated it any more memory?

推荐答案

请确保将选项放在脚本文件名之前:

Make sure you put the options before your script's filename:

• 正确:node --max-old-space-size=10000 index.js
• 不正确:node index.js --max-old-space-size=10000

• Correct: node --max-old-space-size=10000 index.js
• Incorrect: node index.js --max-old-space-size=10000

这个让我有一阵子.
