我安装了单声道和 .net 核心，我正在通过单声道运行它。

有什么建议吗？ （如果可能的话，我想坚持使用 discord.net）

【问题讨论】：

【参考方案1】：

如文档 (https://docs.stillu.cc/guides/getting_started/installing.html) 中所示，无法使用 Mono 运行 Discord.Net。

我建议你切换到 .NET Core。当您现在编译代码时，它将输出一个 .dll 文件（如果 3.1+，则为常规 .exe）

在您的发行版上下载 .NET Core 运行时：https://docs.microsoft.com/en-us/dotnet/core/install/linux

安装后，您应该能够在终端中使用以下命令运行 .dll 文件： dotnet &lt;path_to_dll&gt;

【讨论】：

【参考方案2】：

根据文档，它不支持单声道

在另行通知之前，不支持将此库与 Mono 一起使用。众所周知，该库的 WebSockets 实现存在问题，并且可能会在启动时使应用程序崩溃。 https://docs.stillu.cc/guides/getting_started/installing.html?tabs=vs-install%2Ccore2-1

如果你以.net core为目标，它在linux上运行得非常好，因为d.net以.net standard为目标

【讨论】：

【参考方案3】：

由于缺少上下文，我将假设您使用 .Net Framework 构建应用程序，我建议您切换到 .Net Core。

之后如 Solarcloud 所述，确保您在 Linux 机器上安装了 Dotnet Core，然后您可以在构建后通过 dotnet MyApplication.dll 简单地运行它，导航到文件夹等。

【讨论】：

【参考方案4】：

我只是想尝试一下解决方案，因为我没有看到您提到您在 linux 上安装了 dotnet core。这是一个指南，其中包含一个清单，可按照您的步骤确保其正常工作。 Discord.net 似乎在 .net 核心中。

如果之后仍然失败，请尝试在您的 linux 服务器上运行其他 .net 核心应用程序，看看它们是否有效。我希望这有帮助！
