Node.js | JavaScript堆内存不足，但堆容量只有1GB

我得到这个错误：

FATAL ERROR: invalid table size Allocation failed - JavaScript heap out of memory

但是我使用的是

——max old space size=12288

，我有16GB的内存

使用

process.memoryUsage（）

； 此外，错误总是发生在同一行代码上，即

types.js:~94

，这是我正在使用的库的一部分

这让我觉得某个地方有一个bug，可能在我传递给函数的参数中，但我不知道如何发现它

我应该找什么

完全错误是：

types.js的第94行是decode函数的入口点，定义如下：

  var buffer12 = struct.Buffer(12)

  function decode (buffer, offset, end) {
    var bvalue = buffer12.decode(buffer, offset, end)
    for (var stop = 0; bvalue[stop] !== 0; ++stop);
    for (var i = stop; i < bvalue.length; ++i) {
      if (bvalue[i] !== 0) throw new Error('Found a non-null byte after the first null byte in a null-padded string')
    }
    return bvalue.slice(0, stop).toString('ascii')
  }

var buffer12=struct.Buffer（12）
功能解码（缓冲区、偏移、结束）{
var bvalue=buffer12.解码（缓冲区、偏移量、结束）
对于（var stop=0；bvalue[stop]！==0；++stop）；
对于（变量i=停止；i

你的打字错误

正确的用法是

节点--max old space size=4096 somescript.js

4096在这种情况下是4gb，在您的情况下相应调整它

运行

节点--v8选项

查看所有有效v8选项的列表，

---

或者检查一下，输入错误就在描述中（我已经更正了）。否则它根本不会运行…（它会产生一个“坏选项”错误）这个

require（'v8'）的输出是什么。getHeapStatistics（）.total_available_size

require（'v8'）。getHeapStatistics（）.total_available_size在执行过程中在“12000000000”和“1300000000”之间变化这很奇怪…这意味着限制已增加到几乎13gb，但仍然导致堆内存不足是的…我看不出问题出在哪里。我在另一台计算机上进行了尝试，但情况相同，因此我猜问题出在哪里在代码中…另请参见：
