【问题描述】：

我一直在努力解决这个问题，但无法弄清楚。发布了类似的问题，哪些解决方案建议节点版本有故障或包版本应该被降级/升级。我已经尝试过修改节点版本，重新验证 npm 缓存和许多其他小提琴，但没有一个对我有用。（它发生在运行应用程序-> 电子）

未捕获的异常： TypeError [ERR_INVALID_ARG_TYPE]：“路径”参数必须是字符串类型。接收类型未定义在 assertPath (path.js:39:11) 在基本名称（path.js:1299:5）在 Command.parse (/Users/ben.izadi/Documents/Developer/gsa-cloud-portal/ui/electron_app/publishTest2-mas-x64/publishTest2.app/Contents/Resources/app/node_modules/commander/index.js: 462:30) 在 dispatchUploadFileMessageFromArgs (/Users/ben.izadi/Documents/Developer/gsa-cloud-portal/ui/electron_app/publishTest2-mas-x64/publishTest2.app/Contents/Resources/app/index.js:38:4) 在 WebContents.win.webContents.on (/Users/ben.izadi/Documents/Developer/gsa-cloud-portal/ui/electron_app/publishTest2-mas-x64/publishTest2.app/Contents/Resources/app/index.js: 11:5) 在 WebContents.emit (events.js:182:13)

在我的 index.js 中：

const { app, BrowserWindow } = require('electron')
var program = require('commander');
path = require('path');

var win = null;

function createWindow() {
  win = new BrowserWindow({ width: 1024, height: 768 })
  win.loadFile('./app/index.html');
  win.webContents.on('did-finish-load', () => {
    dispatchUploadFileMessageFromArgs(process.argv);
  })
}

const instanceLock = app.requestSingleInstanceLock();
if (!instanceLock) {
  app.quit()
} else {
  app.on('second-instance', (event, argv, workingDirectory) => {
    if (win) {
      if (win.isMinimized()) {
        win.restore();
      }
      win.focus();
      dispatchUploadFileMessageFromArgs(argv);
    }
  })

  app.on('ready', createWindow);
}

function dispatchUploadFileMessageFromArgs(argv) {
  program
  .option(
    "-m, --modelfile [modelfile]",
    "Model to analyse in the GSA Cloud Platform"
  )
  .parse(argv);

  if (program.modelfile) {
    var absolutePath = path.resolve(program.modelfile);
    var basename = path.basename(absolutePath);
    win.webContents.send("upload-model-file", basename + "," + absolutePath);
  }
}

【问题讨论】：

能否提供更多细节？在 dev 中打包或运行应用程序时出现此错误？
+upvote 我也遇到了这个问题，还没找到解决办法

【解决方案1】：

您需要设置用户键入 --help 时将使用的“名称”

https://github.com/tj/commander.js#usage-and-name

否则，此代码路径将在尝试解析 args https://github.com/tj/commander.js/blob/master/index.js#L446 时失败

我假设这只是 Electron 特定的，在尝试运行捆绑的应用程序时
