When I issue the ps -ef | grep node
it returns pi 988 811 3 17:20 pts/0 00:00:00 grep --color=auto node

Just checked and the module name in the module directory is
MMM-darkSkyForecast and that was created by git cloning as stated in the instructions from the GitHub Repository.

So the name of the directory DOES have a lowercase d in it.

How about I do a full shut down /power off?

Ahh looks like the console was behind Magic Mirror and has these entries.

Well that did not display the DEV console either. Just Magic Mirror standard display. I have my display rotated 90 degree’s if thats a concern. So its in Portrait Mode essentially and not Landscape.

Yup. Thats what I pressed CTRL-SHIFT-lowercase i. Nothing. Strange eh? I will try the method above.

I press CTRL-SHIFT-I with Magic Mirror Running and no console is presented. Actually there is no change at all. Its as if I have not pressed any keys.

Latest version of Magic Mirror on Raspberry Pi Zero W.
Git cloned directory for MMM-DarkSkyForecast. Directory created under MagicMirror/Modules. Ran npm install. . Installed and mentioned 16 severe vulnerabilities.
Whatever?
Modified /config/config.js with entries from git hub repositiory instructions.
Ran linter against config.js. No lint :)
Restarted Magic Mirror. Module does not display. Here is my config.js

That works. Now I am struggling with understanding the IP Whitelist area . I want to open up access to all IP Addresses internally between 192.168.1.2 and 192.168.1.254 as I am unsure which of those IP addresses will be dynamically assigned to the device I use to access the MMM-Remote-Control app.

ipWhitelist: ["127.0.0.1", "::ffff:127.0.0.1", "::1"], // Set [] to allow all IP addresses
	                                                       // or add a specific IPv4 of 192.168.1.5 :
	                                                       // ["127.0.0.1", "::ffff:127.0.0.1", "::1", "::ffff:192.168.1.5"],
	                                                       // or IPv4 range of 192.168.3.0 --> 192.168.3.15 use CIDR format :

@sdetweil Damn you are helpful!
I forgot to uncomment the position setting. Duh. Man little things just slip by. :)

Using Raspberry Pi Zero W with latest version of Buster. MM2 working . used command in first post to install MMM-RemoteControl. Used Master Branch and not Dev. Module directory created sucessfully. Edited config.js with appropriate entries. I dont have anything displaying on screen besides the clock and Holidays .

Its supposed to display the default webpage in the center of the screen. I dont see that . Just black in that area.

Here is the config.js

Thanks ! Thats the process I have been using . Painstaking. Small details always cause errors. Even if I cut and paste right from the github repository using the authors code.

Finally got it to work and upload to my dropbox. Stopping Magic Mirror worked and allowed the Chromium browser to access the drop box webpage, but using my standard credentials (which were correct) just timed out on the logon page. I tried this like 20 times. No dice. Finally logged into dropbox using my google account instead and that allowed me to access a dropbox account that I setup using google credentials.
Ridiculous!

Here is the link to the install.log
https://www.dropbox.com/s/425lhitp7tcftih/install.log?dl=0

Now on to the fun of making just simple syntax errors in the config.js file when configuring modules only to have Magic Mirror 2 complain that there is no config.js or an error. This process is 100 percent suck!

I am having a heck of a time. I cannot use the local browser to visit my drop box site any longer as it directs me to localhost_/ and there is no web address bar to type the dropbox website into.

Well that worked! Looks like Jesse is just too long in the tooth to run Magic Mirror2. Thanks again!

Ok. I will find the image and reimage my micro sd card and then run the install script from the first post and report back. Thanks!

Im going with
Raspbian Buster with desktop and recommended software
Image with desktop and recommended software based on Debian Buster
Version:September 2019
Release date:2019-09-26
Kernel version:4.19

On second thought a smaller image seems more appropriate.

No aversion. Just want to be able to run MM. :) Which do you suggest?
