@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.

Since 6.14.12 there have been a lot of bug fixes, so an upgrade is recommended. And MM works fine with 8.19.2.

Which module are you using and how did you configure it?

Out of curiosity: I can’t find any Python Print Module on the list of 3rd party modules. Which one is it exactly?

I now have no idea how we can solve this properly. Would it perhaps be a solution for you to integrate the module twice, with the two different IDs?

Thanks 🙂 I’ve created a Pull Request.

The module uses the request package, which is not in the dependencies. Try npm install request in the module directory.

@fantasmic78 I am glad that I could help.

It would be good to improve the documentation for such cases. Do you have a concrete suggestion how?

@fantasmic78 This should be possible with most modules. For example, I do this with MMM-JsonTable. The essential thing is that you use the same carouselId for both module instances.
Try it that way and let me/us know if you can’t get it to work.

@jo-0 Okay, I still think that there is something non-standard with the data from the transport company, but we can investigate this further. Can you try the configuration ignoreRelatedStations: true, in combination with both stationIDs?

That is interesting. Apparently, the transport company defined the station ‘Am Zwingerteich, Dresden’ as a related station of ‘Postplatz, Dresden’. Please try stationID: "975242" - this is another ID for ‘Postplatz, Dresden’, which is not related to ‘Am Zwingerteich, Dresden’.

@sirfm locale has to be direcly under config not in the module config: https://github.com/fewieden/MMM-OlympicGames/blob/master/.github/global.png

@mlhote In the meantime it works also with node-fetch v2 for me, so an upgrade seems not to be necessary.

One assumption is that this occurs when you restart the mirror several times. Then the API is often queried in a short time and therefore you are blocked.

Even if this is an old question: MMM-OlympicGames has recently been updated.
