Happy New Year to you too! :-)

Please show the part of your configuration that affects the clock.

There was an additional commit yesterday. I don’t work with an update script, so I don’t know what yours does. In this case just go into your MagicMirror folder and run git pull .

@sdetweil As a soft step, the broken modules could switch to @electron/rebuild. This should also work for docker.

@wishmaster270 Okay, thanks for the explanation! I haven’t been able to read that anywhere in such clear words and I haven’t dealt with the past problems. Then I withdraw my recommendation because I lack the overview.

@wishmaster270 OK, you’re welcome.

Since the thread is also for other developers: I recommend considering my approach, as I consider the other approach (installing to a higher-level directory) to be more error-prone. But it’s a creative workaround.

Yes, but @electron/rebuild is the successor of electron-rebuild. And the “trick” in the postinstall script seems not necessary at all.

The problems on my machine are obviously of a different nature. I’ll investigate that later.

For the original issue it should be worth using @electron/rebuild instead of magicmirror-rebuild or electron-rebuild. I tested it in a virtual machine and it works great. Here is my solution which is less invasive:

What do you think?

@sdetweil npm -v: 8.19.2

For me it looks like this:

To me this looks like a problem with the onoff package. Because if I remove onoff from the package.json, npm i works.

onoff also comes with the dependency epoll, which appears a lot in the error messages.

npm i onoff and npm i epoll produce similar error messages. I think that’s where the main problem is.
