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：
它看起来像这样：
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：

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.
Type H <return> for immediate help.

?
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？
