我正在运行一个 Cheerio 任务，它抛出一个打印此信息的异常(请注意，我添加了打印 spliceArgs 和 array 大小的日志语句:
[14:17:08] Starting 'test:css'...

/home/ole/@superflycss/utilities-fonts/node_modules/cheerio/lib/api/manipulation.js:109
return array.splice.apply(array, spliceArgs);

RangeError: Maximum call stack size exceeded

at initialize.<anonymous> (/home/ole/@superflycss/utilities-fonts/node_modules/cheerio/lib/api/manipulation.js
manipulation.js 中触发此异常的代码行是:
return array.splice.apply(array, spliceArgs);
我还提交了 bug report that has a link加上生成此异常的存储库的构建和测试指令。
有人知道是否有 NodeJS 配置设置可以用来解决这个问题吗？任务总体非常缓慢，需要很长时间才能完成。
更新
只是添加一些附加信息。发生异常时，spliceArgs 数组上有 132,519 项。我记录了最后一个项目的样子，它是一个相当重的物体，如下所示:
{ type: 'tag',
name: 'div',
attribs: { class: 'Test_render' },
children: [],
next:
{ data: '\n ',
type: 'text',
next: null,

next: [Object],
prev: [Object],
parent: [Object] },
root: null },
root: null }
那么，如果我们将 132,000 个婴儿放入一个数组中，也许会导致 Node 爆炸？
第二次更新
由于异常发生时array实例长度为零，我只是返回spliceArgs而不是像这样实际执行拼接:
if (array.length == 0) {
return spliceArgs;
}
现在 V8 内存不足:

另一个更新
这不是一个问题。我尝试在 JSDOM 中实现同样的事情，即使分配了 6GB 内存， Node 仍然无法处理它:
node --max-old-space-size=6000 ./node_modules/.bin/gulp test:css
我对此感到惊讶，因为一旦 nunjucks 循环运行，html 文件的大小就是 9X9X816 模板 block 。这些是循环:

因此，这些内容会渲染出来，然后 gulp 任务会尝试将该 block 复制到文档中的另一个位置，然后再对所有 block 运行语法突出显示。 Node 在复制和追加时遇到内存问题。
最佳答案
我认为您达到了 apply 允许的最大参数大小。如果您引用https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/apply
The consequences of applying a function with too many arguments (think more than tens of thousands of arguments) vary across engines (JavaScriptCore has hard-coded argument limit of 65536), because the limit (indeed even the nature of any excessively-large-stack behavior) is unspecified.
关于javascript - RangeError : Maximum call stack size exceeded caused by array. splice.apply？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44959025/
