Windows 10 中的 MikTeX、Anki 和 Latex。执行 dvipng 时出错。抱歉，dvipng 未成功

我在 Windows 10 中安装了 Anki 和 MikTeX，以便使用 LaTeX 创建 anki 抽认卡。我安装了 MikTeX，因为我读到它是安装 dvipng 和 dvisvgm 的最佳方式。

创建抽认卡示例后，程序尝试编译它时出现以下错误。我不知道如何解决它。有什么建议吗？

Sorry, but dvipng did not succeed.

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

以下是dvipng.log的内容：

答案1

我遇到了完全相同的问题，请尝试打开MikTeX console>Settings并确保已检查Never install missing packages on the fly。对我有用。

答案2

dvipng -D 200 -T tight tmp.dvi -o tmp.png在包含 的目录中的命令提示符中运行dvi.png，该目录与生成的 存储在同一个目录中tmp.tex。Anki 中的错误消息会告诉您那是哪里。在您的情况下是C:\Users\Victor\AppData\Local\Temp\anki_temp\。这是 Anki 执行的相同命令，但失败了，如 中所示dvipng.log。对我来说，弹出一个窗口说我缺少库并需要安装它们。安装后，下次运行命令时窗口就不会弹出。这意味着当 Anki 尝试执行时dvipng不会失败，因为dvipng不会尝试打开一个窗口告诉 Anki 安装库。
