Any module I add turns to blank screen.

[Socrates]

I am new to MM, and i do have some programming knowledge. I understand the concept of braces closing them properly, spacing and closing the loop.
I have been watching youtube and or going through the read me for each of the modules, i follow the instructions to the dot, i will pick up the api keys, or any kind of custom input needed, but every single module turns my mm to blank screen.
I have tried VI i have tried nano, i have tried UI mod Scit and text editor, but each time i copy paste any snippet of code from git, I have to end up aligning the code, it never copies to the config file as desired. Hence i wonder if the code snippet copy paste and spacing and tabs is the problem. How do you work with these.

@sdetweil Dear Sir, you are a genius, i finally got it working. Surely it was an install issue. Using your installation script, and in the past 2 hours i have already inculcated 4 third party modules, and all seems to be working. I might have a question or two later tomorrow when i make more progress, but for now, the main issue is resolved.

@socrates see https://forum.magicmirror.builders/topic/15778/fix-for-black-screen-in-2-16-and-later/6

note that blank screen can also be caused by not following the module install instructions

if the module has a file called package.json, then in the module folder do npm install
even it the instructions don’t say that , then see the link above

also see the ‘how to add a module’ link in my signature (I didn’t write it, but its good stuff)

@socrates also are u doing this with MMOS, or MM installed on a running pi os?

[Socrates]

@sdetweil thanks for your prompt reply. I am running rpi4 OS and then installed MM on it.
The default out of the box modules (US Holidays calendar, and the
compliment msgs shows up), but when i add my own google calendar URL that also does not show up.
Not even a single module i add shows up.
I am following the instructions as on the modules readme pages. I realize some modules require npm install command even after that i get the same blank screen error.

@sdetweil
Let me give you an example of one of the module I am trying to work with. MMM-DynamicWeather
See the error logs.

@socrates said in Any module I add turns to blank screen.:

Cannot find module ‘request’

see the link I gave you in my 1st reply

but looks like u are moving in the right direction

[Socrates]

@sdetweil thanks see my third post , i have the logs uploaded when i tried to install request using
npm install request

and then it shows three more packages that are depreciated.
Not able to install none of those.

[sdetweil]

@socrates said in Any module I add turns to blank screen.:

don’t worry about that… one step at a time…

don’t do npm fund unless u want to contribute money to other developers (outside MM)

[Socrates]

@sdetweil
Do u think i should install MM some other way? I cannot think of anything else.
