sudo: a password is required

[miguelmota]

Running example code doesn't work

index.js

var Sudoer = require('electron-sudo').default;

var options = {name: 'electron sudo application'};
var sudoer = new Sudoer(options);

sudoer.spawn(
  'echo', ['$PARAM'], {env: {PARAM: 'VALUE'}}
)
.then(cp => {
  cp.on('close', () => {
    console.log(cp.output.stdout.toString())
    console.log(cp.output.stderr.toString())
  });
})

output

$ node index.js

sudo: a password is required

Would appreciate it if someone can point me in the right direction.

Thanks!

You're probably on a Mac, and your ticket sounds like its related to this: #39 Basically Mac's tty-tickets feature is causing an issue with this library.

electron-sudo is great, but the devs haven't fixed this yet 😢

I've instead started to use the workaround with sudo-prompt. https://www.npmjs.com/package/sudo-prompt

This is what the sudo-prompt documentation says:

On systems where the user has opted to have tty-tickets enabled, each call to exec() will result in a separate password prompt. Where tty-tickets are disabled, subsequent calls to exec() (but not concurrent calls) will not require a password prompt, so long as the user's sudo timestamp file remains valid.

You should never rely on sudo-prompt to execute your calls in order. If you need to enforce ordering of calls, then you should explicitly order your calls in your application. Where your commands are short-lived, you should queue your calls to exec() to make sure your user is not overloaded with password prompts.

If electron-sudo's devs fix this bug, I'd gladly switch back to electron-sudo since sudo-prompt is still a workaround and doesn't actually fix the issue. sudo-prompt will throw multiple windows asking for the user for each command you want sudo access for. You can get around this by using && but it makes your code VERY VERY messy!

Duplicated #39

I also would like a fix for this one. Will switch to sudo-prompt until then.

If you require sudo prompt on mac then this is all you really need:

var cp = require('child_process')
var isRoot = (process.getuid && process.getuid() === 0)

if (!isRoot) {
  var cmd = `echo hello`
  var prompt = `/usr/bin/osascript -e 'do shell script "bash -c \\\"${cmd}\\\"" with administrator privileges'`
  cp.exec(prompt)
}
