Hey! Another user noticed this issue recently. It seems to be related to the underlying library that detects where LoL is installed, which may be a regression issue due to the riot client changes that were done earlier this year. I'll look into that and add a possibility to supply an installation path soon!

Thank you for your report, leaving this open till fixed. Let me know if you find something out in the meanwhile.

[ManuelHenao]

Hi. Any Update? I really wants this on my stream :(

[Laraakaa]

Looking into this now, hope to provide a solution soon!

[Laraakaa]

I have done the following commit: https://github.com/RCVolus/lol-pick-ban-ui/commit/9fcfbebfd724321149a46b6d5241a1666af017b5

This allows to manually supply an installation directory for the league of legends client. Can you please try to supply it when starting like the following:

npm start -- --leaguePath [YOUR_LEAGUE_PATH]

The default league path is C:\Riot Games\League of Legends on my system.

Can you please try and report back?

[ManuelHenao]

So,

a) it seems to be working for you now. And it also seems that you don't have to supply an installation path. It is normal that this doesn't do anything, since it waits for a champ select to start. b) if you want to run the replay file, you never have to supply an installation path. So just use npm start -- --data recordings/tournament-realm. c) correct way to supply the full installation path would be: npm start -- --leaguePath "C:\\Riot Games\League of Legends" d) As you can read in the README.md, you need to open the frontend like this: http://localhost:3000?backend=ws://localhost:8999 (Source: https://github.com/RCVolus/lol-pick-ban-ui#installation-of-europe-layout)

Does it work for you now?

[ManuelHenao]

It works!!!!!!! thanks

[ManuelHenao]

another question. where i can change team names and scores? i tried on src/app.jsx, but doent work.

[ManuelHenao]

an aditional note. i reinstalled on another path, and just tested npm start withouth path, but with client open, and it works. maybe that was the reason jaja and need say that on readme for idiots like me :)

[Laraakaa]

a) change them in the project root in the file config.json b) so you didn't open the client? Alright, will add that just to be sure! Thanks for that feedback.

[ManuelHenao]
