Error: Cannot find module '@abandonware/noble'

hkayan · 19 October 2021 15:10

Hi,

I am trying to run my customized node on Raspberry Pi 4 that runs DietPi OS. But, I am having errors along the way. I have tried many different things, but no success yet.

The main error that I would like to fix is the one in the title. However, as I am not sure what is the exact reason, I would like to include the errors I got along the way.

The following installation script does not work on DietPi:

bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)

So, I install node.js and node-red via using their recommended script (dietpi-software).

After installation finishes, I run npm doctor and got the following:

npm WARN checkFilesPermission error getting info for /usr/bin/node_modules
npm WARN checkFilesPermission error getting info for /usr/bin/node_modules/.bin

My customized package depends on @abandonware/noble. Hence, first, I install its dependencies:

sudo apt-get install bluetooth bluez libbluetooth-dev libudev-dev

Then, I install the @abandonware/noble package. This one should be done in /mnt/dietpi_userdata/node-red, otherwise will not work. So I run the following:
sudo npm i @abandonware/noble

If I do not install as root I get the following error:

Error: EACCES: permission denied, mkdir '/mnt/dietpi_userdata/node-red/node_modules/@abandonware'

Installation finishes without any error.

Then, I run Node-RED just to see if everything is fine:
dietpi-services start node-red.
I am actually running it as node-red-start as I am very used to it. To see how it is done please see the following discussion. Here is the Node-RED log that I believe it is pretty normal:

19 Oct 14:38:36 - [info] Node-RED version: v2.0.6

19 Oct 14:38:40 - [warn]

Then, I stop Node-RED and install my customized package inside /mnt/dietpi_userdata/node-red.
sudo npm install /home/dietpi/node-red-contrib-ble-sense.

Then I run the Node-RED. But this time, I am getting an error:

19 Oct 15:50:00 - [warn] [node-red-contrib-ble-sense/protocols] Error: Cannot find module '@abandonware/noble'
Require stack:

The thing that I believe it might be related to the problem.

The /mnt is owned by the root: drwxr-xr-x 6 root root 4096 Aug 12 15:16 mnt
I can see the @abandonware/noble package in package.json.

  "dependencies": {
    "@abandonware/noble": "^1.9.2-14",
    "node-red": "^2.0.6",
    "node-red-contrib-ble-sense": "file:../../../home/dietpi/node-red-contrib-ble-sense"
  }

I can see the @abandonware/noble and node-red-contrib-ble-sense in /mnt/dietpi_userdata/node-red/node_modules.
Symbolic link is created for node-red-contrib-ble-sense and owned by the root.
lrwxrwxrwx 1 root root 50 Oct 19 15:47 node-red-contrib-ble-sense -> ../../../../home/dietpi/node-red-contrib-ble-sense. I realized all other packages are owned by nodered and belong to the group nodered.
The /home/dietpi/node-red-contrib-ble-sense is owned by dietpi and belong to the dietpi group
dietpi is only included in dietpi group.

I developed that package via the Raspberry Pi OS without any issues. I would like to continue the development in DietPi for other reasons. I appreciate any feedback.

Your problem is clearly highlighted here. You have mixed up permissions and so will now be suffering.

You should not be installing npm modules with sudo generally.

hkayan · 20 October 2021 12:09

I tried installing via nvm as it is recommended in many places, still no luck.

hkayan · 20 October 2021 13:09

Apparently I was running npm doctor from a wrong path. Now npm doctor generated all OKs.

However npm install asked for permissions again.

Then I followed the instructions mentioned here.

Now, I can install nodes without root permission. I will test developing customized node now.

TotallyInformation · 20 October 2021 14:13

Honestly, it is best to steer away from node version managers, they tend to cause more issues than they resolve.

You will need to sort out the permissions in the folders because those may already be messed up.

hkayan · 20 October 2021 14:17

Hi @TotallyInformation,

I did the fresh install, then applied the fix that I gave a link in my above post. Now I can install nodes without root permission.

TotallyInformation · 20 October 2021 14:30

As always, the rule is - don't use sudo unless you really need to.

I am still getting the error of Error: Cannot find module ‘@abandonware/noble’ when I install my custom node and run Node-RED. However, I have a new lead, I am getting this warning now:

(node:12996) [DEP0128] DeprecationWarning: Invalid 'main' field in '/mnt/dietpi_userdata/node-red/node_modules/@node-red/editor-client/package.json' of './lib/index.js'. Please either fix that or report it to the module author
(Use `node --trace-deprecation ...` to show where the warning was created)

If I check that field, it is

{
    "name": "@node-red/editor-client",
    "version": "2.0.6",
    "license": "Apache-2.0",
    "repository": {
        "type": "git",
        "url": "https://github.com/node-red/node-red.git"
    },
    "contributors": [
        {
            "name": "Nick O'Leary"
        },

            "name": "Dave Conway-Jones"
        }
    ],
    "main": "./lib/index.js"
}

Maybe @knolleary can help with this.
Also, here is log of my main error, that I am trying to solve:

[warn] [node-red-contrib-ble-sense/protocols] Error: Cannot find module '@abandonware/noble'
Require stack:
- /home/dietpi/node-red-contrib-ble-sense/ble.js

- /mnt/dietpi_userdata/node-red/node_modules/node-red/lib/red.js
- /mnt/dietpi_userdata/node-red/node_modules/node-red/red.js

Another lead that I have is, I have realized ~/.npm is empty, but ~/.npm-global has the modules.

That is just a warning when running with Node 16. It has been fixed in 2.1 but has absolutely no bearing on the issue you're experiencing.

hkayan · 20 October 2021 18:29

Alright. I am running Node-RED 17.0.0 though.

knolleary · 20 October 2021 18:30

The deprecation warning was introduced in Node 16.... so Node 17 has it as well.

hkayan · 21 October 2021 13:42

Oh, alright. Node-RED version: v2.1.0 I am not getting that anymore as expected.

Now, the issue is the following:

[node-red-contrib-ble-sense/protocols] Error: EAFNOSUPPORT, Address family not supported by protocol

I have understood the reason. Now digging more to resolve this, sadly all examples I found are related to dockers.

hkayan · 21 October 2021 15:14

I was getting an error as I forgot to enable the bluetooth . Now all works fine, I can finally start developing my package further .

TL:DR for how to develop your own node that depends on @abandonware/noble in DietPi.

Install node.js, node-red, and git via dietpi-software.
cd into /mnt/dietpi_userdata/node-red
Run sudo -u nodered npm doctor. Get all OKs.
Enable bluetooth via dietpi-config.
Reboot.
cd into /mnt/dietpi_userdata/node-red and install @abandonware/noble: sudo -u nodered npm i @abandonware/noble.
Put your customized node folder in the same location as well.
Then install your customized package sudo -u nodered npm i /mnt/dietpi_userdata/node-red/mypackage.
Run node-red: systemctl start node-red.
Now you should be able to see your custom node as well.

hkayan · 25 October 2021 11:05

Update: We also need to grant some privileges to node to do BLE/Bluetooth scan.

sudo setcap cap_net_raw+eip $(eval readlink -f `which node`)
