MagicMirror won't start after installing module

[jani.karna]

Hi, I need help. Yesterday I installed MMM-Wunderlist module. In the description it said to use ‘npm install’ in modules directory and I did. After that my MagicMirror starts with black screen and nothing on it. At startup I get a bunch of errors/warnings which I don’t understand. Can anyone help? I wouldn’t want to reinstall the whole MagicMirror from scratch!

Here is a picture of the MagicMirror shell:

If it doesn’t show, here’s link: https://www.dropbox.com/s/79hkyhehk81hgmh/IMG_0513.jpg?dl=0

EDIT: I actually first ran the ‘npm install’ accidentally from the modules directory instead of modules/MMM-Wunderlist directory which caused MM to stop working.

@jani-karna you accidentally erased a MM file. to fix do

cd ~/MagicMirror
git checkout  modules/node_modules/node_helper/index.js

@jani-karna It seems like the install of dependencies in the wrong directory removed a file, try the following in the terminal:

cd ~/MagicMirror
git checkout modules/node_modules/node_helper/index.js

After that restart your mirror.

Thank you for your replies. I’ll try that when I get back home.

Thank you so much @sdetweil and @strawberry-3-141 , that got my MM up and running again. However, I still get a bunch of “No helper found for module…” for few of them. I don’t know if this is normal.

@jani-karna yes that is normal, if a module doesn’t have the optional file node_helper.js you will see it in the logs
