无法在 Ubuntu 上执行 Chromely 项目 18.04

问：

该项目基于 Chromely lib。 在 Windows 上，项目可以正确执行。但是，在 Linux Ubuntu 18.04.LTS 上，它停止了以下消息：

Possible reasons for this include:

  * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.

(dotnet:5433): Gdk-ERROR **: 15:02:24.971: The program 'dotnet' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
  (Details: serial 219 error_code 2 request_code 12 (core protocol) minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

有没有人在 Linux 上使用 Chromely 有一些经验？执行基于 Chromely 的项目需要做什么..
