Running install results in error "spawnSync yarn ENOENT" on both Windows and Ubuntu

[bjorno43]

After cloning the repository, trying to run the install command with node results in the following error on Windows (which makes sense to me considering the yarn vs yarn.cmd difference):

Running yarn install

}

On Ubuntu however I run in pretty much the same issue:

You have to install yarn. I'll add a note about that to the README.

[bjorno43]

@marijnh Thanks, that did help. Unfortunately I still run into errors after installing Yarn though:

Ah, interesting, that's the same error the CI job is failing with. I'll investigate.

[marijnh]

Seems to have been a yarn bug related to git repository dependencies (similar to this issue, though that is closed). I've temporarily removed those (non-essential) dependencies until I can release them on NPM, and the build is green again.

[bjorno43]

@marijnh Ghehe, I'm hoping you're not getting tired of me, but I'm afraid it still won't install xD Don't worry, it's not a complaint. I'm not in a hurry or anything, just giving you head ups so you know what's going on :D The error I'm getting now while trying to run install is this:

Upgrade to node 14 or 15.

[bjorno43]

@marijnh Yup, that was it! Install was successful! Thanks a lot for your help and patience with me :)

[marijnh]

Great to hear. Things should get smoother over time—you're probably one of the first to even run the multi-package setup outside of my laptop.

[bjorno43]

@marijnh Ah alright, haha. Well I'm very interested in version 6 because it supports collaboration (operational transformation). I know this is already possible with ot.js and CodeMirror 5, but I really want to use a PHP based websocket server instead of NodeJS. Hence I'm very interested in CodeMirror handling most of the OT itself client side.

[curran]

Whoah, CM6 supports OT out of the box? Where is this documented? I'm curious to learn more.

[curran]

👀 Thanks!

[curran]

This is suuuuper fascinating, as I'm using CM5 now with ShareDB, which does JSON OT.

I'm curious if there is any story around presence (e.g. seeing other people's cursors) with this CM6 collab implementation.

One day in the future I hope to refresh this work I did on 2018 and do a proper integration between ShareDB and CodeMirror 6: https://currankelleher.medium.com/codemirror-6-experiments-a3930bf03781

This collab module will probably end up serving as a blueprint for that!

Wow, kudos to @marijnh for the steady stream of development effort on CM6. So much has been added and improved since I was last looking at this project!
