Question

每次运行Iron Python脚本时，我都会遇到错误。我正在使用Windows 11 Ironpython 2.7.12和Python 3.10。这是我遇到的错误，

我确定所有的路径都是正确的，我的C＃脚本看起来像这样，我正在制作一个终端程序，以控制某些灯光，如果您想测试此类型 “ LC” “颜色代码” “ 255，0，0”

using IronPython.Hosting;
using Microsoft.Scripting.Hosting;

Console.ForegroundColor = ConsoleColor.White;
Console.WriteLine("Welcome User");

while(true) {
    Console.ForegroundColor = ConsoleColor.White;
    string UserMessage = Console.ReadLine();
    if(UserMessage == "exit")
        break;
    Console.WriteLine("LP >  " + Response(UserMessage));
}

string Response(string m) {
    if(m == "help") {
        Console.ForegroundColor = ConsoleColor.White;
        return @"help - shows all commands
        LC - Light Command enter a command to controll lights
        
        LC COMMANDS
        
        Color Code - enter color code to set all lights to
        Color - Enter a color to set all leds to
        HEX - Enter a hex to set all leds to";
    } else if(m == "LC") {
        Console.ForegroundColor = ConsoleColor.Yellow;
        LightsAccess();
        return "completed";
    }
    Console.ForegroundColor = ConsoleColor.Red;
    return "PLEASE ENTER A VAILD COMMAND";
}
void LightsAccess() {
    while (true) {
        Console.ForegroundColor = ConsoleColor.Green;
        string UserMessage = Console.ReadLine();
        if(UserMessage != "exit") {
            if(UserMessage == "Color Code") {
                Console.WriteLine("LP-SL-A > Enter Color Code");
                UserMessage = Console.ReadLine();
                ScriptEngine engine = Python.CreateEngine();
                ScriptScope scope = engine.CreateScope();
                var searchPaths = engine.GetSearchPaths();
                searchPaths.Add(@"C:\Python310\Lib"); 
                engine.SetSearchPaths(searchPaths);
                engine.ExecuteFile(@"C:\Users\EvanN\Downloads\GoveeAPI-master\TestConsoleApp\run.py", scope);
                dynamic testFunction = scope.GetVariable("runscript");
                var result = testFunction(UserMessage);
            } else if(UserMessage == "Color") {

            } else if(UserMessage == "HEX") {
            
        } else 
            break;
        Console.WriteLine("LP-SL-A > Color Applied");
        }
    }
}

这是给我错误的部分，

                Console.WriteLine("LP-SL-A > Enter Color Code");
                UserMessage = Console.ReadLine();
                ScriptEngine engine = Python.CreateEngine();
                ScriptScope scope = engine.CreateScope();
                var searchPaths = engine.GetSearchPaths();
                searchPaths.Add(@"C:\Python310\Lib"); 
                engine.SetSearchPaths(searchPaths);
                engine.ExecuteFile(@"C:\Users\EvanN\Downloads\GoveeAPI-master\TestConsoleApp\run.py", scope);
                dynamic testFunction = scope.GetVariable("runscript");
                var result = testFunction(UserMessage);

我的python脚本只有一行，

import os

谢谢您的时间，希望您能提供帮助
