Omnisharp 无法在 Manjaro Linux 上运行

Question

今天我在新设置的 Manjaro 系统上安装了 .NET Core 3.0，但每次我想用 VS Code 打开项目时都会收到错误。以下是“dotnet --info”的输出：

.NET Core SDK（反映任何 global.json）：版本：3.0.100 提交：04339c3a26

运行时环境：OS 名称：manjaro OS 版本：OS 平台：Linux RID：linux-x64 基本路径：
/opt/dotnet/sdk/3.0.100/

主机（对支持有用）：版本：3.0.0 提交：7d57652f33

已安装的 .NET Core SDK：3.0.100 [/opt/dotnet/sdk]

安装的 .NET Core 运行时：Microsoft.AspNetCore.App 3.0.0 [/opt/dotnet/shared/Microsoft.AspNetCore.App] Microsoft.NETCore.App 3.0.0 [/opt/dotnet/shared/Microsoft.NETCore.App]

要安装其他 .NET Core 运行时或 SDK，请执行以下操作：
https://aka.ms/dotnet-download

使用创建项目

dotnet new mvc -o MVCTest

运行没有问题。但是当我打开这样的项目时，会出现以下错误消息：

我已经将“omnisharp.path”：“latest”添加到我的settings.json中，但这并没有改变任何东西。

非常感谢你的帮助！
