在electron develop环境下运行良好，但是打包后，运行失败

os:win11
electron:11.5
node:12.18.3

Answer 1 · 2022-09-09T10:48:51.000Z

方便看下你的子进程执行文件吗？看样子是子进程没创起来，然后向子进程发消息就报错了

Answer 2 · 2022-09-09T10:49:11.000Z

或者描述一下这个子进程执行文件做了什么

Answer 3 · 2022-09-09T11:28:03.000Z

@nojsja 我在子进程做最简单的操作，都不行，在develop环境下良好

child.js

const { ProcessHost } = require('electron-re');
ProcessHost
  .registry('test',() => {
    return 55555
  });

Answer 4 · 2022-09-09T11:35:30.000Z

@nojsja #1 是否是同个问题，目前不支持prod环境吗？

Answer 5 · 2022-09-09T11:38:13.000Z

你可以试下别安装在C盘或者使用管理员权限启动应用，我正在排查原因

Answer 6 · 2022-09-09T12:21:30.000Z

用管理员权限启动一样报错，目前目录权限也没问题，应该和C盘无关。

Answer 8 · 2022-09-09T13:09:17.000Z

https://blog.yasking.org/a/electron-fork-not-running.html

找到原因了，定位了挺久，跟权限和代码无关，就是 fork 中的 js 脚本 require 加载外部模块的问题，生产环境下查找路径不对，导致 js 脚本中找不到 Electron。

Answer 9 · 2022-09-09T13:09:44.000Z

我看看能不能找个好的解决方案

Answer 10 · 2022-09-09T13:34:35.000Z

好啊，谢谢！要是能优雅的解决就好了😂

Answer 11 · 2022-09-10T15:04:12.000Z

electron-re@1.2.4 已修复 ChildProcessPool 子进程 prod 环境 crash 问题。原因是 Electron 的内部 bug，注意： 不能在子进程执行脚本中使用 require('electron')，否则会造成打包后生产环境下发生严重错误，目前Electron官方还未出方案。

Answer 12 · 2022-09-15T02:55:45.000Z

厉害啊，我抽空试试，感谢大佬！

Answer 13 · 2022-09-16T09:27:24.000Z

我重新使用了1.24，发现不报错了，但是也不会运行啊，不返回结果

Answer 14 · 2022-09-16T09:47:07.000Z

我这边测试打包之后运行起来正常的，你可以调试看看

还是一样报错，刚才没报错是因为我把log关了。

electron:11
node:12
os:win11

Answer 16 · 2022-09-16T13:49:17.000Z

找到原因了，你打包Electron应用的时候启用了 Electron-Builer 的 asar 源代码加密吧？

{
  ...
  "asar": false,
}

asar 加密后 node.js 找不到你的子进程执行文件，我测试时关闭了asar。如果你要在保持asar开启的情况下使用进程池的话，最好将你的执行脚本放入外部数据目录而不是应用代码目录。

Answer 17 · 2022-09-16T14:01:44.000Z

的确启动了asar加密，好，我测看看！谢谢大佬
