fix for black screen in 2.16 and later

DarrenHill

Just wanted to say thanks for the fix here.

Did an update and hit exactly this with MMM-GmailFeed and the request module.

Installed it back (with an audit fix afterwards) and now all up and running again :)

@darrenhill said in fix for black screen in 2.16 and later:

with an audit fix afterwards

don’t do those… many times leave more trouble than they fix…
we can’t suppress the audit warning message

DarrenHill

@sdetweil OK, thanks for the pointer.

Always kinda worried when that style of message pops up, for security and suchlike.

I see from the update that my node is very much out of date, so now just backing things up before setting the update script onto it to try and bring that up too.

sdetweil

@darrenhill upgrade is for MM, not node, (altho it might do it, works sometimes, need to move to n) …

easiest is using the node version of nvm, called n

do

sudo npm i n -g
PATH="$PATH"
n 16

then node 16 will be installed…

note that you will have to do another npm install in the mm (and maybe module folders)
this the upgrade would do (with force instead of apply)

n also allows you to SWITCH versions, or use a particular version for ONE app…
see n --help

DarrenHill

@sdetweil - I did it via your update script, and it has updated Node from v10.x to v16.x (or at least that is what appears to have happened from what I could read).

It’s quite an old install that just sits on my desk and largely gets left to its own devices. It is in a PiTop Ceed rather than a true mirror, and basically the only thing it runs is MM (it’s actually a dual-boot via PINN also with RetroPie, but the Raspi OS partition is essentially only MM). So no need to keep things focussed to one app or anything like that - no issue of cross-contamination.

All is working fine after the update though, so no problems.

@darrenhill cool. thx for the feedback

@sdetweil
Ran your update script today and now got black screen. Should I still check each module for json files and npm install or will the script have done that already?
How to I go about trying to troubleshoot this ? Any help is much appreciated!

sdetweil

@np27np27 want to see installers/upgrade.log

same process as listed in post 1

‘request’ is NOT the only library missing

the messages tell you what needs to be added

Looks like the issue is the PIR sensor module. I believe there is a new PIR module?
