how do i resolve this?

Thank you

where have you downloaded the node from?

Does it say to use sudo?

3

Which node red node is it that needs that? It should have installed it automatically.

4

i tried npm install i2c-bus i still have errors.

i m trying to install this node https://flows.nodered.org/node/node-red-contrib-pca9685

It's advisable to install the i2c package first. Refer to The i2c npm page for more informations. This may require manual steps (e.g. enabling kernel modules). Please only proceed with this module once you've managed to properly install the i2c package, to simplify troubleshooting.

I tried installing i2c package as suggested i have node-gyp errors also so i m trying i2c-bus.

Thank you

I don't see where in those instructions it says to use sudo or install it globally, but I don't think that is what is causing the errors. If you look in the issues on that node (i2c-bus) on github you will see others having similar problems, it seems it is not compatible with node 10.x. It has not been updated for three years and there does not seem to be any response to the mulitple issues raised against it. I think maybe there is a better i2c node, though I have no experience of them.

6

Is there a reason you installed using sudo ?

I just installed the library in the standard way. The installation was smooth and error free.

Hey, i actually face the same issues on an Raspberry Pi.

I could help myself by downgrading the node version (with nvm) to v8.-ish.
Then node-red-contrib-pca9685 worked, however other nodes like sqlite3
did not anymore. So downgrading is not an option for me.

10

You would also need to remove and reinstall / rebuild sqlite node as that also needs to compile against the correct node version

11

Hi thank you for the suggestions.

Its working fine now
Thank you

12

So what did you end up doing to get it to work?

13

I downgrade it as suggested by mrgrizzly above.

  1. https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally

  2. npm install i2c-bus

  3. downgrade nodejs to v8.15.1
    https://www.abeautifulsite.net/how-to-upgrade-or-downgrade-nodejs-using-npm

  4. Install node-red-contrib-pca9685 via node-red pallete

Thank you.

14

The above steps seems to work with jessie bt not stretch. I fresh installed stretch n followed the steps i can install PCA9685 node but whn run it doesnt work. Hope there's better solutions

Thank you.

15

I would suggest you contact the author (as it is a contrib node) to make them aware of the issues you are having

16

Have followed the steps but no luck, any suggestions?

npm i -g arrowmeiwaracing/node-red-contrib-pca9685

Relying on a fork of the original module, updated in January, specifying i2c-bus at 5.x.x so will work for a while.
