@sdetweil Thank you immensely for you help. It is running now.

@sdetweil
Looks like I ran npm install on modules dir.

pi@MagicMirror2:~/MagicMirror/modules $ git clone https://github.com/Elaniobro/MMM-nyc-transit.git

I will correct as you noted.

@sdetweil said in MMM-NYC-Transit Module (Black Screen):

npm start

Looks like some files might be missing.

I did clone the repo as required??

@sdetweil I use pm2

@sdetweil Yeah that was my bad… the mirror loads now without the module…
:man_facepalming_medium-dark_skin_tone:

@sdetweil pm2

After adding disabled: true

Got "Please create a config file " error

@sdetweil Aww OK will adjust

@sdetweil I figured thats why I said it was weird.

This is what the module looked like in my config

  {
              module: 'MMM-nyc-transit',
              disabled: "true",
              position: "bottom_right",
              header: "Next Train",
              config: {
                     apiKey: '9b76b0b756f7f9a76d4fe883075c00cf',
                                displayType: 'list',
                                mtaType: 'train',
                                stations: [
                                        {
                                        stationId: 95,
                                        walkingTime: 5,
                                        dir: {
                                                upTown: false,
                                                downTown: true
                                             }
                                        },
                                        {
                                        stationId: 95,
                                        walkingTime: 5,
                                        dir: {
                                                upTown: true,
                                                downTown: false
                                             }
                                        }
                                        ],
                                updateInterval: 300000
                }
                },

These are the steps I just tried…
recreated original circumstances that caused black screen (added Module to config) and yes the black screen still exist.

I assume that means there is issue with module config settings.

I tried to launch the Dev console, but it did not launch in same page as black mirror screen but a white page.

I will wait for your response before making changes to config.js file again.

@sdetweil I added the module to config, disabled!
The Mirror loads as normal.
Something I find weird is even with the module disabled, its header is still shown.

I realized I have since removed the config. I will re-add and check again.

@sdetweil Thanks for the response. There are no errors shown.

Hi All,
I am getting a black screen after installing this module. Can I get some help reviewing what might have caused it. This is a new install on a RPI 3.
I read this post thinking I may get insight into issue but to no avail. I even registered for a new API key and that wasn’t it.

This is my current config.

Any help or insight will be most appreciated.

Thanks for this post. I am about to put it to good use.

Hi All,
I’m Shonari. I’m 34 and live in Brooklyn, NY. I work at a startup building cellphone charging kiosks. Love to make and have a new found affinity for Raspberry Pi. Made a MagicMirror last December and recently decided to upgrade it to a Pi3 and MagicMirror2. Love the modules. Thanks to all those who contribute their time to this great project.

Cheers,
