Question

我正在尝试使用.net-core创建一个电子应用程序。它在所有步骤中都运作良好，并且在我测试和调试应用程序时完全没有错误。但是不幸的是，当我使用电子打包程序打包应用程序时，执行.exe文件时出现此错误。

在主进程未捕获的异常中发生了javaScript错误： TypeError [ERR_INVALID_ARG_VALUE]：参数'args'无效。已收到{cwd： 'D：\ win \ release-builds \ gen \ resources \ app.asar \ bin'} 在Object.execFile（child_process.js：218：11）在Object.module。（匿名函数）作为execFile 在exec（child_process.js：160：18）在ELECTRON_ASAR.js：746：23 在portfinder上（D：\ win \ release-builds \ gen \ resources \ app.asar \ main.js：122：22）在听D：.... 在Server.server.listen D：.... 在Object.onceWrapper（events.js：273：13）在Server.emit（events.js：182：13）在emitListeningNT（net.js：1364：10）

这是我的main.js文件的内容：

(function() {
    var childProcess = require("child_process");
    var oldSpawn = childProcess.spawn;
    function mySpawn() {
        console.log('spawn called');
        console.log(arguments);
        var result = oldSpawn.apply(this, arguments);
        return result;
    }
    childProcess.spawn = mySpawn;
})();

    });

    if (shouldQuit) {
        app.quit();
    }
}

app.on('ready', () => {
    if (isSplashScreenEnabled()) {
        startSplashScreen();
    }

    portfinder(8000, (error, port) => {

    }
}

function startSocketApiBridge(port) {

    startAspCoreBackend(port);

    io.on('connection', (socket) => {

        if (splashScreen && !splashScreen.isDestroyed()) {

        const os = require('os');
        if (os.platform() === 'win32') {

            console.log(`stdout: ${data.toString()}`);
        });

}

package.json文件的内容：

{
  "name": "XXXXXXXX",
  "version": "1.0.0",
  "description": "XXXXXXXXXXXXXXXXXXX",
  "main": "main.js",
  "author": "Gregor Biswanger",

  },

}

和program.cs文件：

public static void Main(string[] args)
{
    BuildWebHost(args).Run();
}
public static IWebHost BuildWebHost(string[] args)
{
    return WebHost.CreateDefaultBuilder(args)
        .UseStartup<Startup>()
        .UseElectron(args)
        .Build();
}

打包的.net-core电子应用程序无法运行
