Blank mm after update

[kvicksson]

Just to be clear, I’m a girl… ;)
The module worked as a charm before the update. So you think I should just skip the apostrophe on the updateInterval and hideBorder?

[sdetweil]

@kvicksson ok… before the update it worked…

does the module contain a package.json file?

if so you must also run npm install in the module folder as the version of electron changed in 2.8.0

in the future, i hope my update script will help solve these problems…

@kvicksson the rules are text needs quotes (’ or " matching)
numbers and true/false should NOT have quotes… as they become strings and not numeric or logical values

if variable == true will fail with quoted values…

well with the config:check he would not have found the error, would he?

In this case perhaps not, but it cannot hurt to run it in order to exclude error(s) before and after this part of the config.
Normally a 'true' versus true would not cause a black screen, but I might be wrong.
And a trouble shooting guide would have to start with the config:checkIMHO.

u don’t know how the module code might fail…
which is what causes the blackscreen to begin with

seems odd that there would be two invocations of these modules…

but as a test, in MagicMirror/config/config.js add

    disabled: true, 

to both those modules, and restart mm and see what happens

[sdetweil]

missing a required node package ‘del’

no package.json to inform the user

[sdetweil]

warning, warning… copy and save

MagicMirror/modules/node_modules/node_helper (folder, which contains index.js)

then

cd ~/MagicMirror/modules/mmm-weatherchart
npm install del

check for a missing
MagicMirror/modules/node_modules/node_helper folder
and if so, copy it back

i opened an issue with mmm-weatherchart

I have only one mmm-weatherchart module present.
When disabled everything is fine.
However, I forgot to remove the single quotes, as I just copy/pasted the config from the thread.
Corrected it, but now I get even stronger things.

0|mm  | WARNING! Could not load config file. Starting with default configuration. Error found: Error: Cannot find module 'del'

I do not have any string with ‘del’ in my config :worried_face:
