Read the statement by Michael Teeuw here.
Any module I add turns to blank screen.
-
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 abovealso 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?
-
@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

@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
-
@sdetweil thanks see my third post , i have the logs uploaded when i tried to install request using
npm install requestand then it shows three more packages that are depreciated.
Not able to install none of those. -
@socrates said in Any module I add turns to blank screen.:
Not able to install none of those
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)
-
@sdetweil
Do u think i should install MM some other way? I cannot think of anything else. -
@socrates well, i would start with one module at a time…
save the current config.js
copy the config.js.sample to config.jsconfirm MM runs
add one module
resolve any missing dependencies
i don’t THINK u need to resinstall, but if u want to
then use my install script… see
https://github.com/sdetweil/MagicMirror_scriptsit doesn’t look like config.js editing is the problem, but if so, try my MMM-Config module which generates a form for config , see
https://github.com/sdetweil/MMM-Configbut missing libs are a pain in the rear… just no way to know when it will hit
note that the instructions link I posted will load ‘request’ or any other missing lib
IN THE MODULE folderso, if u find ANOTHER module with the same problem, then u have to load it THERE TOO
over and overyou can do it in the MM folder instead, BUT… be warned… if you do an upgrade, the libs will be tossed as they are not referenced by the base, and are considered a security risk (in NPM, not the MM code) so, you could get to do it all over again, …
(I am considering making a change to my upgrade script to try and detect this… not sure yet) -
@sdetweil Thanks i am gonna follow these steps and let you know.
I am literally installing one module at a time, but none of the 3rd party module works. Even if i try to edit the inbuilt module that MM came with for eg:- the calendar, i try to add my own google calendar, it wont work. (meaning my calendar wont show up).
Do u have recommendations of which modules i can initially start with so that all the basic pre-requisite libraries get installed? -
@socrates the defaults ones work pretty reliably…
for mail, the url for the cal ics lnk should download the ics file when used in a browser…
that is what the cal modules useswhat modules have u been trying over than default?
-
@sdetweil
I have tried todoist, the calander ext2 module, dynamic weather module, several others. I think i might have an installation issue… I will just reformat my card and re-install using your script.
So after i install rpi, do i run ur script in terminal, and follow the prompts? -
@socrates said in Any module I add turns to blank screen.:
do i run ur script in terminal, and follow the prompts?
yes, just copy paste the one line for install in a terminal window
-
@sdetweil
So i have installed mm using your script, and i am up and running, havent installed the modules yet, but that is because i am not able to shutdown mm using pm2 command, mm has been started using pm2 via your script.
None of these commands work
pm2 restart mm
pm2 stop mm -
@socrates said in Any module I add turns to blank screen.:
pm2 stop mm
cause its not called mm…
pm2 status
will show u the name , you can also use the number
or all to stop everything

So everything is working out great for me, i have added some great modules, and in the processing of adding more.
The only one thing i am not able to figure out is the measure of unit for the weather.
I am in the US, in texas, and even if i use the imperial unit it wont show it correctly and the weather is totally off.{ module: "MMM-Weather", position: "top_right", header: "Weather Forecast - Katy, TX", configDeepMerge: true, config: { debug: false, updateInterval: "15m", // 15 minutes updateFadeSpeed: 500, api: { key: "98dbcccba012ef0fd49c86665a0df584", latitude: "29.71490", longitude: "95.83688", units: "imperial" }, display: { CurrentConditions: true, ExtraCurrentConditions: true, Summary: true, ForecastTableColumnHeaderIcons: true, HourlyForecast: true, DailyForecast: true, Precipitation: true, Wind: true, InlineIcons: true, Feels: true, SunCondition: true, Humidity: true, UV: true, Beaufort: true }, personalize: { hourlyForecastInterval: 3, maxHourliesToShow: 3, maxDailiesToShow: 3, concise: false, colored : true, forecastLayout: "table", forecastHeaderText: "" }, labels: { high: "H", low: "L", timeFormat: "kk[h]" } } }, Have a look a this code.. and the partial screenshot of my magic mirror through vnc viewer -
