Unable to install

Hi,
Trying to use this library and I'm getting the following error:
...

usleep(info[0]->Int32Value() * 1000);

Any ideas?
Thanks so much

I might be some changes in the V8 engine. This module was designed using Node version 11.5.0. You seem to be using 12.18.2.

[meg768]

Are you using a node version manager?

Hi,
Thanks for the quick response. I've switch to version 11.5.0 and now I'm getting the following :(
internal/modules/cjs/loader.js:1251
return process.dlopen(module, path.toNamespacedPath(filename));

Error: The module '/home/pi/code/robotpi/api/node_modules/rpi-ws281x/build/Release/rpi-ws281x.node'

NODE_MODULE_VERSION 67. This version of Node.js requires

Remove the node_modules directory and try again.

[gizbo]

Are you using a node version manager?

Yes I am using nvm.

[meg768]

When changing node versions it is best to remove the node_modules directory entirely. It may be partially compiled with the previous version of node.

Resolved? May I close this issue? Of course, will have to look into node version 12 and up...

Well no I didn't managed to get it working/install. Perhaps a problem with my environment, I will try from a clean slate, maybe then. If you could share me your setup, I could try again.

Thanks so much for help,

Installing 11.15.0 fixed it for me. I had to use the unofficial builds to download a tar and manually copy the executables because I'm using a pi zero

And just a reminder. The default GPIO18 is pin12 on pi zero.
