Just to update this thread. It worked on a pi3 so I assume it was a memory issue. All running as expected now.

@tbowmo Just 256MB I was going to get a Pi3 anyway for something else, so I 'll see if that makes a difference. Thanks.

Shame it was nice to use something just sitting around.

Thanks @tbowmo. I used the cli. It seems to be a common problem with sqlite3 and the Pi, although the solutions elsewhere haven't worked for me yet. I'm using an old Pi as that is what I have lying around... Basically, the node-gyp is starting to build but then just hangs. I guess it could be a memory issue on my old pi...

Hi. I'm having the same problem getting these extensions to install on my (original) Pi. Going back to a fresh version of stretch, then reinstalling the node-red extensions didn't help.

It appears to be failing on sqlite3, which I can't add myself via npm either - as there are no pre-built binaries for sqlite3 (4.0.1) or node (8.11.3). Letting it build it itself with node-gyp (the standard fallback) just hangs. Grateful for any thoughts?
