@sdetweil I did that several times earlier. Also deleted the folder for the module and reinstalled several times.

I either get the black screen or error screen.

Im obviously doing something wrong but after 2 days of working with 1 module, its been deleted and I am moving on.

@marchvet show the messages at startup
either from npm start or if using pm2, then

pm2 logs --lines=50

@marchvet black screen means a missing library

so u have to read the messages to find out what is missing. and then install it in the module folder

there are lots of modules that will be impacted.

and more than 1 missing library

@marchvet One of the easiest things to screw up within the config.js is the lack of commas. If you cut and paste a lot of the modules config.js suggested entries, they omit the last comma.

For example;

{
       module: 'MMM-Multimonth',
       position: 'top_left' // can be any of the postions
},

See that comma at the end?

If you omit that, you’ll get the error screen if it’s not the last module in the list.

Even though it’s not “normal” - I put a comma even if it’s the last on every item. This eliminates that error.

As for the blank screens, the likely (but not always) module that’s missing is request. There’s documentation on how to install that elsewhere in the forum
