如何增加pandoc执行中的堆内存？ [英] How to increase heap memory in pandoc execution?

问题描述

我正在将docx转换为epub。文档包含很多图像。当执行转换时，我有错误：

 pandoc.exe：Heap exhausted;当前最大堆大小为1073741824 
字节（1024 MB）;使用'+ RTS -M'来增加它。 
执行作业时出错！
  

我正在使用Node.js。

任何人都可以协助我如何增加堆大小？

更新：

 我增加了大小，直到2GB。但是pandoc仍然显示错误
Pandoc.exe内存不足
  

是否有可能解决这个问题？

解决方案

您可以增加可用于pandoc的内存，比如 2048 MB ，其中包含：

pre $ pandoc.exe + RTS -M2048


但潜在的问题可能是Pandoc使用 zip-archive 压缩EPUB文件。看来您目前至少需要与您想要生成的未压缩的EPUB一样多的内存（但是我会在提交错误报告之前验证它）。

也应该缩小你的图像一点点，因为2GB对于电子书来说似乎相当过分（即使压缩时它有点小）。

I am working on converting docx to epub. Document contains lot of images. When execution of converting, i have error:

 "pandoc.exe: Heap exhausted; Current maximum heap size is 1073741824 
   bytes (1024 MB); use `+RTS -M' to increase it. 
   Error while executing job!"

I am using Node.js.

Can any one assist me how to increase heap size?

Update:

I have increased size till 2GB.  But pandoc still shows error 
"Pandoc.exe out of memory"

Is it possible to solve this issue?

解决方案

You can increase the memory available to pandoc, to say 2048 MB, with:

pandoc.exe +RTS -M2048

But the underlying problem is probably that Pandoc uses zip-archive to zip the EPUB file. It seems you currently need at least as much memory as the uncompressed EPUB you want to generate (but I'd verify this before filing a bug report there).

You probably also should scale down your images a bit since 2GB seems rather excessive for an e-book (even if it's a bit smaller when compressed).
