如何在 Electron 中使用 node-pty 正确启动 shell 环境？

Question

I have an Electron App that's using node-pty to create a pseudo-terminal instance. This instance is created as follows:

const pty = require('node-pty');
const os = require('os');
const shell = process.env[os.platform() === 'win32' ? 'COMSPEC' : 'SHELL'];
const ptyProcess = pty.spawn(shell, [], {
  name: 'xterm-color',
  cols: 100,
  rows: 40,
  cwd: process.env.HOME,
  env: process.env
}); 

When I launch the app from the vscode terminal using ( electron. ) everything works as expected. Ie the shell can find all programs just like it would in cmd.exe or Terminal.app.

However, if I build the app, and open it via double clicking on it, I notice that my path does not contain certain directories such as /usr/local/bin/ , which can cause certain programs (like brew ) to fail with "Not found" errors.

Notably, if I launch the electron app from a terminal on mac using open -a MyElectronApp everything works as expected.

I suspect my app needs to initialize the path differently somehow. However, since this is a cross-platform app, I'd like to avoid doing anything like "if os.platform == 'darwin' load /etc/paths".

Any help would be greatly appreciated. Please let me know if you need more information. I assume my issue is probably due to a misunderstanding/ignorance of shell environments!

Faced same issue. Used https://github.com/sindresorhus/fix-path

process.env.PATH was not available for the electron process in production mode. The above fix-path fixes the issue
