我正在开发一个歌本编辑软件，正在 AppVeyor（Windows 环境）上自动测试。
在测试我的软件之前，AppVeyor 需要安装 MikTex 和一些软件包：我通过以下方式完成此操作平均每分钟程序。MikTex 安装运行良好。
我的问题是软件包安装有时成功（后来的失败是由于我的软件造成的）有时失败。
我没有在日志中看到任何可以解释这种行为的差异（如下所述）（也许下载时间除外？）。还有其他方法可以调试此命令吗？（我已经使用了--verbose）
在线差异（右侧为成功）
成功

Sorry, but "MiKTeX Package Manager" did not succeed.
The log file hopefully contains the information to get MiKTeX going again:
C:/projects/patadata-pdf/miktex/miktex/log/mpmcli.log
You may want to visit the MiKTeX project page, if you need help.
Command exited with code 1

由于无法完成下载，因此此处的安装失败。
没有给出原因，但通常是因为服务器超载或者你的互联网连接非常慢或者破碎的。
当我告诉我的学生如何安装/更新 MiKTeX 时，我总是告诉他们这种安装/更新中断是可能发生的。然后只需重新启动该过程即可。重新启动的过程会识别已安装的新软件包并继续使用非当前软件包。我的一个学生不得不重新启动安装过程 13 次，因为他使用的网络连接非常差……
