SOLVED Cannot find module 'module-alias/register'

DerRheingold

Hi,

since two days now, I keep getting this error-message when (re)starting MagicMirror:

App threw an error during load
Error: Cannot find module 'module-alias/register'
    at Module._resolveFilename (module.js:455:15)
    at Function.Module._resolveFilename (/home/pi/MagicMirror/node_modules/electron/dist/resources/electron.asar/common/reset-search-paths.js:35:12)

    at tryModuleLoad (module.js:432:12)

On a regular base I make a git fetch etc. to make sure MagicMirror is up to date. This morning somehow it wouldn’t start anymore. That’s the error I get when manually starting via

cd ~/MagicMirror
DISPLAY=:0 npm start

Any idea how to fix this? … and even more: any idea what might have caused this?

Cheers

@DerRheingold did u try to update to the latest release?

if so, there were two steps

git pull
npm install
did u do the second?

@sdetweil said in Cannot find module 'module-alias/register':

npm install

Thanks, yes that was very helpful. Helped indeed. However I also had to fix one module by deleting and pulling it again, but now it works fine. Thanks once more

Hmm - same thing for me. Too much time on my hands, so I updated. And now I get

@amanzimdwini and u also did

npm install

after the git pull…

need everyone to start using the update script…
from here

@sdetweil
I did (read my way through all the posts)

HOWEVER,
https://forum.magicmirror.builders/topic/10859/new-update-upgrade-script-ready-for-testing/2
told me to run

bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"

and that made me a new installation that did work.

Sometimes you have to sledgehammer things, I guess.

Thanks for offering to help,
karl

@amanzimdwini that post says

I also have a newer installer that resolves a lot of problems with MM

post 1
says

given that we will have a regular update quarterly, and we have such a large number of new users experiencing troubles after updates (mostly cause they have a ton to learn)… I have developed a script I would like to get included for future updates…

but glad u got it working… many cannot just reinstall easily

amanzimdwini

@sdetweil
wait - wasnt’ that the newest?
Sorry - working on something else right now, but please send latest and best installer link

THANKS FOR THE HELP,
Karl

sdetweil

@amanzimdwini

please read the page here for the multiple scripts I provide

https://github.com/sdetweil/MagicMirror_scripts

each provides the string to cut/paste to execute the specific function
install,
update
screen saver
pm2

@sdetweil THX! Will do.
