How to get rid of annoying popups in Windows 10?

[nakamorichi]

How do I disable the popup windows that pm2 generates in Windows 10 when starting, restarting or reloading a Node.js app? From the perspective of rapid server-side development, this is very annoying...

[Unitech]

Would it be an issue because of the way we spawn processes?

• https://github.com/Unitech/pm2/blob/development/lib/God/ClusterMode.js#L52
• https://github.com/Unitech/pm2/blob/development/lib/God/ForkMode.js#L94

I don't know if I have to customize something on this code segments,

[soyuka]

{detached: true should get rid of this error but it is not available for cluster.

[Unitech]

interesting, maybe @ThisIsMac47 will have a look at this on the next weeks

[vmarchaud]

After testing, the detached option doesnt hide popups on Windows, i think that nodejs spawn a shell to spawn the process.
I will investigate more in the next days.

[vmarchaud]

Okay so :

• In fork mode, you shouldnt have popups in the dev branch since now
• In cluster mode, unfortunately, we dont have control on the popup cause we use the cluster implementation of nodejs.

If you get any popup apart of cluster mode, respond to this issue to report it, i will investigate for each one.

[soyuka]

Because we can't get detached: true in cluster?

[vmarchaud]

They use the function fork, we can use detached: true only with spawn.

[soyuka]

Yes ok so if that's the main reason, the only solution is to port cluster into pm2 instead of using the nodejs cluster.
Did you try a simple cluster implementation without pm2 to see if it pops up too?

[vmarchaud]

I wasnt able to reproduce with a simple cluster implementation, this might coming from the fact that we are a spawning a child from a forked child or something like this.
We manage to delete the popups in cluster mod by rewriting the implementation on the branch of a forked cluster implementation, we will talk about how include this into future release of pm2.

[ajithr]

Is this issue fixed or any workaround available? I have faced the same issue when using cluster mode with watch option. The node window opens multiple time when saving the file.

[vmarchaud]

@ajithr No, like i said, the problem come from nodeJs implementation of the cluster mode. I suggest you to develop in fork mode.

[gustavohenke]

For me what has been working quite well is to use --no-daemon.
However, if pm2 was previously started as a daemon process, then this flag has no effect and the popups keep appearing, unless I run pm2 kill.

[ghost]

@gustavohenke I followed your instructions, but it did not work for me. I am using pm2 2.0.19 on Windows 8.1 and I still get a popup window everytime I use child_process.exec()

[vmarchaud]

@centigrade-thomas-becker The fact a popup is spawning when you call child_process.exec isn't coming from pm2, it come from the system of spawning a child process of node itself, you may add detached: true to the spawning config and it will not spawn any popup.

The problem of #2182 is that in cluster mode, we can't control how the process are spawn, so we can't add this options to hide the popup under windows.

[soyuka]

@centigrade-thomas-becker you should try to use child_process.spawn and add a {detached: true} option.

[mswaminath]

I wanted to share what I did to overcome the popup.
Initially I will npm start my app that starts pm2 as well, then I will do pm2 stop all immediately. After that when I again do npm start, it just pops up only once and never again.

[tayler-king]

Do we have any updates on this for a proper implementation that will patch this issue?

I use PM2 when locally developing. It's becoming an issue to run pm2 kill after every script run. Consoles interrupting me when working is not welcome.

[raghavmac]

Try this,

1. npm start your project as usual (pop-up's keep on coming up)
2. Stop the project (Ctrl-C)
3. pm2 delete <project-name>
4. Again npm start (this time it stops popping up)

Hope it works!

[tayler-king]

I use the process json file to launch my pm2 instances so I do not believe that will work for me.

Any fix to this? Just asking 😄

@mswaminath Can you please post your pm2 config, and how you spawn your child processes?

[parthvakharia]

Any permanent solution for this ??

[jasonayerp]

npm i -g pm2@4.4
pm2 update

try it!

Confirmed this resolved the issue for me too.

[githubUser982]

I'm sorry, forever did indeed have the problem too. My bad. I used node-hide-console-window to work around the problem because v4.4 did not seem to help.

[karikera]

is this issue abandoned?

[dr3adx]

piece of shit of a repo when u cant fix simple issue like this that EVERYONE is experiencing

[dr3adx]

fkin monkey developers

[selimdev00]

{detached: true should get rid of this error but it is not available for cluster.

Perfect!

[Faf4a]

npm i -g pm2@4.4
pm2 update

try it!

Thanks! This worked just fine for me.. struggled with this issue for multiple months now.

[githubUser982]

Interesting, I wonder why it works for some.

[Tosinkoa]

Please any update on this?

What's the general consensus on how to avoid this issue on Windows ?
No offense but this is troublesome to deal with. I do not understand how Windows can be marked as stable when there's chaotic behaviour like this present in the application.

Node: v18.17.0
pm2: 5.3.0

Again I don't mean to be rude but some of use have no choice when it comes to pm2. There are already large enterprise projects that depend on it I can't just go around ecosystem.config.js files that are hundreds of lines.

We all know Windows has it's problems and that most of the time as a dev you have to work around its shorcomings but after 7 years this issue should have a statement or solution.

[punowo]

I wrote a program to resolve this issue.

Just use pm2 start noc -- app arg1 arg2 ... to replace pm2 start app -- arg1 arg2 ....

Will all pm2 commands still work ?
Like pm2 delete all and logs ?

[githubUser982]

There's no consensus. 4.4 works for some, not for others, node-hide-console-window is an option when it doesn't. I haven't tried noc.

I can only conclude that the maintainers don't care for windows, I suppose.

Sorry, how do I make use of node-hide-console-window non-programatically, when it comes to pm2 I only have to deal with a ecosystem.js with a lot of envs.

[tooolz]

Welp back to nodemon for development I guess

this did it for me.
pm2 seems nice for a production environment, but for developing on windows? forget about it, nodemon to the rescue

For what it's worth, I eventually made it work with pm2-installer.
It works on my machine, using the old powershell provided by default by Windows and setting the pm2 service to local service. I also had to deal with how pm2 recognizes npm on Windows by avoiding 'script':'npm' and just passing the npm-cli.js directly to 'script'.

[ve3]

I'm using pm2 v 5.3.0

It keep popup powershell window on every socket.io emit the message in node app. (popup and closed but very annoying because I can't focus on other window while it pops up.)

Is this related to this issue?

[hyroqi]

PSA, This window will keep popping up if your app has a crash or problem, I used nodemon to determine what was causing the crash (and the window popup), fixed it and pm2 stopped the unexpected behaviour

[hicodify]

I am using version 5.3.0 and I can confirm that the problem continues to occur when running on cluster mode. By any chance do you know if there is a solution for this on Windows?

I have to moved to use NSSM.

[vite-vit]

You can run both source and pm2 in git bash. Not in cmd or powershell

[wxfred]

A python cmd window always popups in Windows 10 when I do the pm2 start ecosystem.config.js, how to avoid it

// ecosystem.config.js
module.exports = {
  apps: [
    {
      name: 'python',
      script: 'poetry',
      args: ['run', 'python', 'server.py'], // a python flask server
      instances: 1,
      exec_mode: 'fork',
      autorestart: true,
      watch: false,
    },
  ],
};

As @jermitval pointed out the last working version was 4.4
Between versions 4.4 and 4.5 a few dependencies were updated. Looks like the offending one is Vizion

Change Vizion to 0.2.13 and the problem disappears
Run
where node
i.e. C:\Program Files\nodejs\node.exe
open any terminal and go to node_modules\pm2 subfolder i.e. C:\Program Files\nodejs\node_modules\pm2
npm i vizion@0.2.13

Looks like this Vizion package needs a fix because 0.2.13 is an old version with some vulnerabilities. But the popup is so extremely annoying esp focus stealing when editing files with watches on them that for now I'd rather use this old version.

Solution 2 Instead of downgrading vizion you can disable it altogether(whatever it does) and the popups will stop
In process.json

{
  "script": "src/index.js",
  "watch": ["src"],
  "name": "Whatever",
  "vizion": false,
  ...
}

or in command line
pm2 start index.js --no-vizion

[marui-obj]

In my case I have to flush terminal every interval time, so every time it flushes it keep popups annoying terminal at same interval time as it flush, my solutions is just removing that line from my source code.

This is my testcase in Python

# test.py
import time
from os import system, name

def flush():
    if name == "nt":
        _ = system("cls")
    else:
        _ = system("clear")

def main():
    print("foo")
    flush() #Comment me
    time.sleep(1)

if __name__ == "__main__" :
    while(True):
        main()

Is this related?

[matys1]

@DVLP setting vizion: false in the config file indeed solved the annoying popups in dev. Though that's really a workaround and not a proper fix. Bizzare that this issue has been open for 6 years.

[abaksha-sc]

@matys1 , thank you! Adding vision: false to config file really solved the problem when parameter --no-vizion has no effect. Maybe because for development instance I use command Debug right from VSCode:

[Unitech]

I have disabled vision by default in the prochain release of PM2,
Could you make a try and let me know if that works for you:

npm install pm2-beta -g
pm2 update

Or with bun:

bun install pm2-beta -g
pm2 update

Thanks
