How to add modules. For absolute beginners.

@TheSij how do you start MM? npm start, or pm2 start ?
if npm start, look at the messages shown in the terminal window after the npm start, or better yet, redirect the messages to a file, so you can look at them later
npm start >somefile 2>&1
(same as on windows)if pm2, then pm2 logs --lines=100 should display the messages…
black screen,m typically means some library required by a module is not loaded, usually because of a missed install step for the module…
the area u read on github, is the same as the file README.md after the git clone, so you can look at the instructionsgit clone
cd modulename
npm install -
@sdetweil - this is the log when I started MM just now…

tack Error: missing script: start
5 verbose cwd /home/pi/MagicMirror/modules/MMM-soccerwhat did you type?
the command is
cd ~/MagicMirror npm startto run MM, you must start from the MagicMirror folder… not a module folder, not the users home folder…
if you use pm2, it will issue the right commands from the right place

@sdetweil - apologies, I was in the wrong directory. This is the terminal response…

i suspect you did not do the required install in the
MagicMirror/modules/MMM-PrayerTime folderper the instructions
Installation Navigate into your MagicMirror's modules folder execute git clone https://github.com/slametps/MMM-PrayerTime.git **if this module does not run correctly,** try npm install async -
@sdetweil said in How to add modules. For absolute beginners.:
I am 110% sure I installed the module in the right directory. I always check before I execute it. I’ve just checked the directory, and the module repository is in the right place. I’m executing the ‘npm install async’ command now. Fingers crossed!

what does that mean?
-
I opened an issue on the MMM-PrayerTime module github, for him to create a package.json file for this async dependency and let the system handle it
https://github.com/slametps/MMM-PrayerTime/issues/43 -
@sdetweil - as in, the files for that module is in the MM modules folder. Sorry if I’m using the wrong terminology.
So, after running the ‘npm install async’, it found three low vulnerabilities, which I’ve asked for them to be fixed.
-
@sdetweil - thanks. I think I’ve got it working. The module is finally showing in the MM dashboard. Thanks very much for the guidance, and @Mykle1.
-
@TheSij ignore the vulnerabilities, more trouble than its worth
-
@sdetweil - too late. Sorry, I went ahead before getting this advice. I’ll remember for next time.
-
@TheSij many times the ‘fixes’ force new code, which breaks old code, so you fix one problem, but the system is dead.
more times than not fixing adds new issues to the list, different than u started with. almost NEVER does the list go away.
and some of the vulnerabilities matter IF you have your pi connected to the internet where others are interacting with it (logon, save money, messages, …) MM is just pulling update notices. not allowing unsolicited inbound connections… -
@sdetweil - understood. Thanks!

Ahh, see? Well done. Don’t sweat it. We’ve all experienced these problems. I promise, it gets easier. The more you learn the easier it becomes. Have fun!

For the record, I did not have to install dependencies.
-
@Mykle1 because some other module already had. npm install would have resolved that, if he had provided the package. json

What if no errors are generated and yet the widget is not shown on the screen? Where do we start troubleshooting?
TIA

It would help if you named the widget (I assume you mean module) and posted your config entry for that module. Please post in a code block.

And everything @sdetweil says. :-)
