Hey, just installing my laserweb server on raspberry pi 3b.

Hey,
just installing my laserweb server on raspberry pi 3b. i followed the instructions on "https://cncpro.yurl.ch/documentation/installation/36-install-raspberry-pi."
i got this error:

npm WARN ajv-keywords@2.1.0 requires a peer of ajv@>=5.0.0 but none is installed. You must install peer dependencies yourself.
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: 7zip-bin-win@2.1.0 (node_modules/7zip-bin-win):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for 7zip-bin-win@2.1.0: wanted {“os”:“win32”,“arch”:“any”} (current: {“os”:“linux”,“arch”:“arm”})

npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for 7zip-bin-mac@1.0.1: wanted {“os”:“darwin”,“arch”:“any”} (current: {“os”:“linux”,“arch”:“arm”})

the server seem to start yet. is this something i have to worry about?( the first one ) thanks in advance…

hm. when i try to connect to the server via chrome on my mac i get: this site can´t be reached on chrome and the moment i tries to connect to the raspberry the server goes down with: /home/pi/lw.comm-server/node_modules/node-static/lib/node-static.js:348
