我在 macOS 上有一个简单的 .NET Core 控制台项目paket.dependencies

storage: symlink
source https://www.nuget.org/api/v2
nuget FsLab

和paket.references

FsLab

和程序

open XPlot.Plotly
[<EntryPoint>]
let main argv =
    [1 .. 10] |> Chart.Line |> Chart.Show
    0

当我dotnet run这样做时，我会收到警告

warning NU1701: Package 'XPlot.Plotly 1.5.0' was restored using
'.NETFramework,Version=v4.6.1' instead of the project target framework
'.NETCoreApp,Version=v2.2'. This package may not be fully compatible with your
project.

和一堆类似的，然后是错误

Unhandled Exception: System.ComponentModel.Win32Exception: Permission denied

看起来它正试图在浏览器中显示图表。我有三个问题：

  1. 到底是怎么回事？
  2. 如何让它在浏览器中显示？
  3. 如何以编程方式将图表导出到文件（例如 PNG）？
