Electron error: Cannot find module 'envsub'

asd · Apr 6, 2023, 8:03 PM

Hi there,

my MM unfortunately does not load anymore.
I already installed envsub via npm which did not help.

Is there anyone who has an idea what this could be?

Thank you very much, greatly appreciated!

The logs state the following:

@asd ok, got it.

you forgot the second step of upgrade

git pull && npm install

you MUST run npm install

and POSSIBLY. have to run npm install or electron-rebuild in all the installed modules
due to the possible nodejs change and electron change.

sdetweil · Apr 6, 2023, 8:10 PM

@asd how did you upgrade?

manual or scripted?

if manual what commands did u enter?

asd · Apr 7, 2023, 9:10 AM

@sdetweil thanks for your help.

The MagicMirror was running well on git commit f14e956 from Feb, 7th 2023.
When I upgraded via git pull within the ~/MagicMirror folder, the miror would not start anymore.

Hence I tried to reverse the git pull via git reset --hard f14e956 which unfortunately did not help either.

Besides this, I previously ran the standard apt update && upgrade -y. However, the mirror worked fine when restarting after this via pm2 restart mm. S o I do not think it was based of this.

For reference, I run MM on a Raspberry Pi 4.

@sdetweil awesome. It works again. Thank you very much. greatly appreciated!

I have done my updates like this before and seem to have forgotten it this time.

Roncham · Apr 21, 2023, 2:00 AM

I have the same problem. I updated using

git pull && npm run install-mm

I also ran npm install in each module, only 1 seemed to update. Rebooted and still get same error:

@raspberrypi:~/MagicMirror $ npm run start

> magicmirror@2.23.0 start
> DISPLAY="${DISPLAY:=:0}" ./node_modules/.bin/electron js/electron.js

@Roncham I can only say that the npm run did not work

from the MagicMirror folder do

npm install --omit=dev

Roncham · Apr 21, 2023, 2:38 AM

@sdetweil said in Electron error: Cannot find module 'envsub':

npm install --omit=dev

That worked thank you!

@sdetweil (posting it in case somebody else is going to need it)

In my case, the NPM error was:

npm ERR! code EBADENGINE
npm ERR! engine Unsupported engine
npm ERR! engine Not compatible with your version of node/npm: magicmirror@2.31.0
npm ERR! notsup Not compatible with your version of node/npm: magicmirror@2.31.0
npm ERR! notsup Required: {"node":">=22.14.0"}
npm ERR! notsup Actual:   {"npm":"8.19.4","node":"v16.20.2"}

MagicMirror 2.31.0 needs at least Node 22, but through APT command, the Raspbian repos go up to 16. To solve this, I installed N, the Node version manager as an NPM module, then udpated Node that way.

$ sudo npm install -g n

added 1 package, and audited 2 packages in 2s

$ sudo n 22

  installing : node-v22.14.0
       mkdir : /usr/local/n/versions/node/22.14.0
       fetch : https://nodejs.org/dist/v22.14.0/node-v22.14.0-linux-armv7l.tar.xz
     copying : node/22.14.0
   installed : v22.14.0 (with npm 10.9.2)

Note: the node command changed location and the old location may be remembered in your current shell.
         old : /usr/bin/node
         new : /usr/local/bin/node
If "node --version" shows the old version then start a new shell, or reset the location hash with:
hash -r  (for bash, zsh, ash, dash, and ksh)
rehash   (for csh and tcsh)

$ node -v
v16.20.2
$ hash -r
$ node -v
v22.14.0

Then rerun npm run install-mm and it will work.

Hope it helps. :)

@hecaru yes, and IF you use my upgrade script, it will handle that for you…

same place as the install script
