二进制adb文件，electron构建之后在某些系统内无法访问

[icepy]

• Electron version: 1.7.10
• Operating system: Mac 10.13.1

Expected behavior

可以启动adb service通过adb devices 获取到设备id

Actual behavior

A JavaScript error occurred in the main process

Uncaught Exception:

Error : spawn ENOTDIR

adb放置在resources/mac/adb，代码写在src/index.js中，整体的目录结构如下：

resources // adb二进制文件
src //源代码
.babelrc
package.json

代码：

import os from 'os';
import path  from 'path';
import childProcess from 'child_process';
const spawn = childProcess.spawn;
const PLATFORM = {
  MAC: 'mac',
  WINDOWS: 'windows',
  UNKNOWN: 'unknown'
}
function fetchPlatform(){
  switch(os.platform()){
    case 'darwin':
        return PLATFORM.MAC;
      break;
    case 'win32':
        return PLATFORM.WINDOWS;
      break;
    default:
        return PLATFORM.UNKNOWN;
      break;
  }
}
const platform = fetchPlatform();
const rootDir = path.resolve(__dirname,'../');
const RESOURCES = path.resolve(rootDir,'resources')
const _adbPath = path.resolve(RESOURCES,platform);
function fetchAdbPath(){
  switch(platform){
    case PLATFORM.MAC:
        return path.resolve(_adbPath,'adb');
      break;
    case PLATFORM.WINDOWS:
        return path.resolve(_adbPath, 'adb.exe');
      break;
    default:
        return false;
      break;
  }
}
export function start_server(callback){
  let adbExecPath = fetchAdbPath();
  if (adbExecPath){
    let adb = spawn(adbExecPath,['start-server']);
    adb.stdout.on('data', function (data) {
      console.log('stdout: ' + data);
    });
    adb.stderr.on('data', function (data) {
      console.log('stderr: ' + data);
    });
    adb.on('exit', function (code) {
      typeof callback === 'function' && callback(code);
    });
    adb.stdin.end();
  } else {
    throw new Error('Not Found Android Debug Bridge');
  }
}

How to reproduce

将上述代码做为一个npm包，假设叫adb-test-a，然后在electron工程里，npm install adb-test-a，调用start_server，必抛错误：Error : spawn ENOTDIR。

问题依旧没有解决，问了一圈社区里的人，都说是electron的问题，希望能帮忙指导一下，怎么解决。

ENOTDIR means not a directory, this usually means that you're passing a wrong path, check that using fs.stat or anything similar

Edited as it is irrelevant

@KagamiChan i know, but my example code did not use fs or anything similar, please help me, check my example code .

some os the dir path is app.asar, some other is app.asar.unpacked, i am very confused about this.

not understand

step：

1. add adb file to app.asar
2. use electron-util#fixpathforasarunpackpath，get app.asar.unpacked
3. use exec run adb command
