Hi there.

I'm trying to install the SDS011 sensor node in my rapsberry pi3, you can find it here: [https://flows.nodered.org/node/node-red-contrib-sds011](https://flows.nodered.org/node/node-red-contrib-sds011)  
Actually i'm running npm@6.13.4 and node@v12.15.0.

I wish that it's not a problem with compatibility between the node and my version of nodejs, or something like this.

When i try to run the script: npm install node-red-contrib-sds011, this is the answer.

Any ideas?  
Thanks.

You should be in the .node-red directory when you run the npm install command, I suspect you may still get the error though.

That node depends on serialport v6 - I think you will need version 7 or even 8 in order to compile on nodejs 12. It may work if you drop back to node 10.

thx.

how may i do that? I try with:

but the node version is still v12.15.0

You probably need to uninstall 12 first and remove nodesource.list from /etc/apt/sources.list.d dir then retry that command

What does

show? Post it here.

Also you did run  
`sudo apt install nodejs`  
after running the curl command I hope.

ok, i tried to uninstall nodejs following this guide:

>
> Apparently i needed to completely remove my node.js and npm installation in my mac mavericks because i have installed various version of node.js from brew and nodejs.org website. After removing node from Brew, i am still able to access my node on my...

then i run:

`curl -sL https://deb.nodesource.com/setup_10.x | sudo bash -`  
`sudo apt-get install nodejs`

If i try to run node-v or node --version, it shows an error:

`bash: /usr/local/bin/node: File or directory doesn't exist` (translation from italian)

but, if i run  
`apt policy nodejs`

this is the answer:

```auto

I've tried to install node red and the node for my sensor again.

Result by installing the sensor node: no errors but some warnings. I have suppose to see the node in my node red dashboard (the one that i reach with [http://myipaddres:1880](http://myipaddres:1880)), but it doesn't appear.

Did you do the following, which is necessary after changing the nodejs version?  
First stop node red then reinstall node-red to build it with the new nodejs and then rebuild any other nodes installed

```auto
sudo npm install -g --unsafe-perm node-red
cd ~/.node-red
npm rebuild

```

then restart node-red

Stop node red then start it using  
`node-red-start`  
and post the full output here. Also post the result of  
`npm list node-red-contrib-sds011`

Here you have the output for `node-red-start` command. I cover the ip address with "x".

```auto
Start Node-RED
 
Once Node-RED has started, point a browser at http://xxx.xxx.x.xxx:1880
On Pi Node-RED works better with the Firefox or Chrome browser
 
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot

results for `npm list node-red-contrib-sds011` command:

```auto

```

And with this results, maybe i understand the problem... is that the right path? 🙂

Thanks for helping.

If you install nodes manually, on the Pi always change to the `.node-red` directory before using the `npm` command. You might want to remove that node, `cd .node-red` and reinstall it.

Thankyou so much to all of you for the help!

Ok, here i am...

thanks to you, I think that i'm at a good point (and consider that it's my firt rednode project.

Actually, i try to set a flow implementing a serial input, the sensor node, and 3 payloads.

I set the serial node with this sets

and I hadn't touch the SDS011 configuration. I tried to deploy, and I show you the results... ideas? ☹

Looks like incorrect baud rate. What does a debug node on the serial port show.

Hope that i set the flow in the correct way to answer you.

Presumably that is not what you are expecting. Are you sure the baud rate is correct?
