generaly caused by
maybe:
- you have installed this module with root account (by using sudo ?)
- git clone with sudo
- npm install with sudo
notes: ALL modules and MagicMirror program sould be installed with user account (pi with raspberry)
and NOT with root account (sudo command)If you install with sudo command is equal to modify or rewrite a file in windows system -> you can’t access or modify it with simple windows user account

I installed this module yesterday and did a little debugging. The request for the graphic works ok (code=200), but the saving to disk doesn’t work for some reason.
The web URL error also means not found. I am away from my system til late today before I can look at it again
-
ok, we have a timing problem… the file is written, but erased
workaround
change these lines in node_helper.js
http.get(options, function (response) { var pngFiles = payload.mmDir + 'modules/mmm-weatherchart/cache/*.png'; del([pngFiles]);
to
var pngFiles = payload.mmDir + 'modules/mmm-weatherchart/cache/*.png'; del.sync([pngFiles]); http.get(options, function (response) {

@Bugsounet ok thank you for the explanation. I tried it with and without sudo, but it doesn’t matter. I have left the last clone of the module without the sudo command.

Today it was very weird, I started my MM² to reinstall the module as @Bugsounet said, and the weatherchart was visible (the first time on my MM²)! After that I decided to change the region of the weatherchart, unfortunately the weatherchart is now gone again. No region is working reliable.

@prototype0815 see the fix above

@prototype0815 see my reply above

@prototype0815 better solution, download my fork of the module with both fixes
stop your magicmirror
cd ~/MagicMirror/modules mv mmm-weatherchart mmm-weatherchart.original git clone https://github.com/sdetweil/mmm-weatherchart.git cd mmm-weatherchart npm install cd ~/MagicMirror npm start

Hey guys thank you all for your help! The sdetweil fork is working very well if “del” is installed too.
:handshake: :thumbs_up: great community -
@prototype0815 said in Black screen when insert https://github.com/paphko/mmm-weatherchart:
if “del” is installed too
what does that mean? del was added to the package.json file and should have been installed when u did the new npm install after cloning my repo…
"dependencies": { "del": "^5.1.0", "request": "latest" }
