如果包含来自网站的 markdown 图像，MiKTeX 无法将 jupyter 笔记本转换为 pdf

我遇到这个问题已经很长时间了，我不知道还能做些什么。

在 Jupyter Notebook 上，你可以通过以下简单命令在 markdown 单元格中添加来自网络的图像：

![any text](image url)

它看起来像这样：

在此处输入图片描述

每当我尝试将此笔记本导出为 pdf 时，都会出现错误。

这是我通过 Jupyter Lab 尝试时遇到的错误：

nbconvert failed: PDF creating failed, captured latex output:
Failed to run "xelatex notebook.tex -quiet" command:
notebook.tex:408: Unable to load picture or PDF file '
dvipdfmx:fatal: Image inclusion failed for "https://i.imgur.com/MQdEUrY.png".

No output PDF file written.

Sorry, but xelatex did not succeed.

The log file hopefully contains the information to get MiKTeX going again:

C:\Users\Caique\AppData\Local\MiKTeX\miktex\log\xelatex.log

这是日志文件中的“FATAL”文本：

2021-03-10 19:22:12,105-0300 FATAL xelatex.core - Invalid argument

最后，当我将其导出为 LaTeX 并尝试使用 MiKTeX（使用“pdfLaTeX+MakeIndex+BibTeX”编译器）进行编译时，出现此错误：

LaTeX Warning: File `https://i.imgur.com/MQdEUrY.png' not found on input line 408.

! Package pdftex.def Error: File `https://i.imgur.com/MQdEUrY.png' not found: using draft setting.

See the pdftex.def package documentation for explanation.

?

请注意，这些错误与另一个笔记本（因此是另一个图像）有关，但是每次笔记本中有来自网站的图像时都会发生这种错误。

有人知道我该如何解决这个问题吗？
