Not able to uninstall module from Palette "unknown module: node-red-contrib-play-audio"

General
1

Hi there!

I please need some advise on how to get a module uninstalled, if - in my case - the palette manager says "Failed to remove: node-red-contrib-play-audio / unknown module: node-red-contrib-play-audio".

The log only tells

2024-02-14T08:25:38.862Z Remove : node-red-contrib-play-audio

...and nothing else...

In the meantime I (think, I) uninstalled the module via npm, but node-red continues to show the module in the palette.
Can anyone help me out?

Thanks!
Florian

Assuming that you have a conventional install of node-red then go into your .node-red folder and run
npm remove node-red-contrib-play-audio
Copy/paste the full output please, including the line where you typed the command.
Then restart node-red and see if it is still there.

Hi Colin,

it's an install on a Raspi running DietPi (Debian / Raspbian) where the installation is sitting at /mnt/dietpi_userdata/node-red/

Here's the output:

I then tried it again with sudo:

...and it is still there... :frowning:

Contrib nodes are typically not installed in the installation directory. They are normally installed in the user directory. The node-red user directory by looking at The startup log. Typically though it is ~/.node-red

Try

cd ~/.node-red
npm remove node-red-contrib-play-audio

Also, in case you installed it globally do this too

sudo npm remove -g node-red-contrib-play-audio

Is that the folder where your node red flows file is?

6

Yes. And there it is inside the projects/projectname subfolder.
That's where I get it installed via dietpi-software...

7

Can you show us the output in the command window when you stop and restart node red please. It should start with Welcome to node red.

8

I assume that you did not install node-red using the recommended method for diet-pi. Running on Raspberry Pi : Node-RED

Here you are...

Yes, that's true.

It isn't possible to run this script on dietpi since the system recognizes the platform and tells me to use "dietpi-software" and stops.

dietpi-software manages the installation process itself.

That's also the reason why the platform is running node v21.6.1 and not the recommended version... but it's the distribution that - in my opinion - is running best for my purposes. It is a nice and lean distribution.

11

That is odd, as it says on that page that it is suitable for diet-pi. Perhaps the doc is out of date.

Go into

That means that the user dietpi has not got full write permissions into the node_modules folder, possibly because you used sudo to install a node at some point. Probably there are some root owned folders or files there. I suggest you ensure that all files and folders in dietpi_userdata are owned by dietpi and try again.

12

I am not sure, but maybe last time I only tried the script once, and it stopped. I didn't try to install it via apt-get... Think I have to give it a second chance...

Okay - I will try to ensure the correct ownership and try again. Thanks for that hint.
