RangeError: Maximum call stack size exceeded caused by array.splice.apply?
我正在 运行 执行 cheerio 任务，它会抛出一个打印此内容的异常（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'...

return array.splice.apply(array, spliceArgs);

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);
我还向产生此异常的存储库提交了 bug report that has a link 以及构建和测试说明。
有人知道是否有我可以用来解决这个问题的 NodeJS 配置设置吗？总的来说任务很慢，需要很长时间才能完成。
更新
只是添加一些额外的信息。 spliceArgs 数组在异常发生时有 132,519 个项目。我记录了最后一项的样子，它是一个相当重的物体，如下所示：
{ type: 'tag',
name: 'div',
attribs: { class: 'Test_render' },

next:

所以也许如果我们将这些婴儿中的 132,000 个塞进一个导致节点爆炸的数组中？
第二次更新
由于 array 实例长度在发生异常时为零，我只是返回 spliceArgs 而不是像这样实际进行拼接：
if (array.length == 0) {
return spliceArgs;
}
现在 V8 运行内存不足：

另一个更新
这不是 cheerio 问题。我尝试在 JSDOM 中实现同样的事情，即使分配了 6GB 的 ram，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 循环具有 运行，html 文件的大小为 9X9X816 模板块。这些是循环：

所以这些呈现出来，然后 gulp 任务尝试将该块复制到文档中的另一个位置，然后语法突出显示是 运行 所有它。节点 运行 复制和追加时出现内存问题。
我认为您达到了 apply 允许的最大参数大小。如果你引用 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.

所以也许如果我们将这些婴儿中的 132,000 个塞进一个导致节点爆炸的数组中？
第二次更新
由于 array 实例长度在发生异常时为零，我只是返回 spliceArgs 而不是像这样实际进行拼接：
if (array.length == 0) {
return spliceArgs;
}
现在 V8 运行内存不足：

另一个更新
这不是 cheerio 问题。我尝试在 JSDOM 中实现同样的事情，即使分配了 6GB 的 ram，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 循环具有 运行，html 文件的大小为 9X9X816 模板块。这些是循环：

我认为您达到了 apply 允许的最大参数大小。如果你引用 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.
