Unable to detect the forge installer!

Question

Unable to detect the forge installer!

Zatan16 opened this issue 5 months ago · comments

My minecraft instance (offline) is not able to detect the forge installer I then tried to install it but any method of trying to install wasn't working. So, are there any PolyMC specific methods that I should try to install the forge installer. I tried to make an instance without selecting the forge option and it worked perfectly (and laggy, that's the only reason I need forge, for OptiFine)

This is the error that I am getting:

What ways did you try to install?
Does Fabric with, e.g. Fabulously Optimized work?

Science Worldz · Answer 2 · Mon Jan 15 2024 12:43:21 GMT+0800 (China Standard Time)

I installed the JAR file and then tried to allow executing permissions but there was no such option to allow executing.
I tried using sudo chmod +x filename to allow the executing permissions but still, it wouldn't execute
And then I used java -jar filename to run it and it worked, but when I selected the .minecraft folder of my instance, it said The directory is missing a launcher profile. Please run the minecraft launcher first. and it closed when I pressed "OK"
Edit: I also clicked on the "Install Forge" option and then selected "Download All" in the Edit Instance Menu but still am getting the same error.

swurl · Answer 3 · Mon Jan 15 2024 22:58:16 GMT+0800 (China Standard Time)

Okay. What happens when you create a new Vanilla 1.20.4 instance, select Edit Instance, then Install Forge, and install 49.0.19? Doing that has no issues for me.

For now though, I would highly recommend using Fabric with Fabulously Optimized, it's significantly better than OptiFine on top of being open-source. If installing Fabric fails as well, then you probably are lacking write permissions or something.

Thank you, and one last thing. Does Fabulously Optimized have a feature where light blocks glow when in your hand and when dropped or do I need to manually install another mod for it? Also for the feature where I can zoom in to things.
Edit: I forgot to tell you, the former doesn't work but the latter does. Thank you for your help.

Ok, it might be worth it to investigate this further but since I can't reproduce there's not much I can do for now.

I forget if Fabulously Optimized includes it, but if not, I think LambdDynamicLights is what you need. I believe it needs Cloth Config as well, but I think that's included too.

@binex-dsk PolyMC depends on Zeker's ForgeWrapper for launching Forge, and he added support for 1.20.3 and 1.20.4 in 1.5.8 so the fix would be updating the ForgeWrapper on our meta server

swurl · Answer 7 · Sat Jan 20 2024 23:23:06 GMT+0800 (China Standard Time)

Where is this handled? I don't see it on any of the meta repos.

HeyaGlitz · Answer 8 · Sat Jan 20 2024 23:39:16 GMT+0800 (China Standard Time)

https://github.com/PolyMC/meta-scripts/blob/master/meta%2Fcommon%2Fforge.py
FORGEWRAPPER_MAVEN but I don't know how our maven works so you'll have to ask Lenny or something

PolyMC/files#2

adamsong · Answer 10 · Sun Feb 11 2024 10:07:40 GMT+0800 (China Standard Time)

I'm still seeing this after that pr was merged

HeyaGlitz · Answer 11 · Sun Feb 11 2024 10:11:08 GMT+0800 (China Standard Time)

There's something wrong with the meta server, Lenny is investigating it

swurl · Answer 12 · Wed Feb 14 2024 21:07:44 GMT+0800 (China Standard Time)

@adamsong the meta server as fixed, are you still facing issues or is everything good?

Sorry about the delay, still getting the error

from Lenny:

first close PolyMC, then delete the folder %AppData%/PolyMC/meta and then it should work after re-opening PolyMC

adamsong · Answer 15 · Thu Feb 22 2024 23:08:34 GMT+0800 (China Standard Time)

Where is that on linux?

HeyaGlitz · Answer 16 · Thu Feb 22 2024 23:42:22 GMT+0800 (China Standard Time)

~/.local/share/PolyMC/

adamsong · Answer 17 · Fri Feb 23 2024 02:12:41 GMT+0800 (China Standard Time)

Works now, thanks

Doesn't work for me. Modpack Fear The Nightfall v12 from curseforge. I tried deleting polymc/meta directory. I'm using PolyMC 6.1 portable on windows.

I can't remember off the top of my head, but it might be in PolyMC/files.

If not, post your error, it might give some clues

XakepSDK · Answer 20 · Thu Feb 29 2024 02:06:11 GMT+0800 (China Standard Time)

I don't have PolyMC/files directory, but I have PolyMC/meta directory. I tried deleting it, didn't help.
This directory %AppData%/PolyMC/meta does not exist.
Here is the error: https://gist.github.com/XakepSDK/2c1a1b2edf7d67087360eaf9772d3591

swurl · Answer 21 · Thu Feb 29 2024 05:47:08 GMT+0800 (China Standard Time)

Are you 100% sure that you closed PolyMC before deleting the directory?

atzaveri · Answer 22 · Thu Feb 29 2024 08:07:28 GMT+0800 (China Standard Time)

aparently polymc of any version stoped download forge installer, check under the folder: \libraries\net\minecraftforge\forge\1.19.2-43.3.5\ if you have forge-1.19.2-43.3.5-installer.jar
btw, you can solve this just downloading the correct forge version > https://maven.minecraftforge.net/net/minecraftforge/forge/1.19.2-43.3.5/forge-1.19.2-43.3.5-installer.jar
place on the folder and try again

I'm having the same issue trying to run forge modpacks from 1.19 and 1.20. Fabric modpacks work fine, so does vanilla mc.

This is what the error code looks like and I'm pretty sure its a forge installer issue.

Kaydax · Answer 24 · Thu Feb 29 2024 13:38:03 GMT+0800 (China Standard Time)

This is most likely due to the fact every single forge installer has been updated, thus causing checksums to change and prob some other things. This was due to something on mojang's end where they decided to kill off one domain, causing every installer to just break

Kaydax · Answer 25 · Thu Feb 29 2024 14:26:26 GMT+0800 (China Standard Time)

I just made a PR that fixes the issue here. Now we just wait for Lenny to merge it and from there polymc should just work

swurl · Answer 26 · Fri Mar 01 2024 12:33:38 GMT+0800 (China Standard Time)

@XakepSDK @atzaveri @shroneko The PR's been merged. Try it now after deleting the meta directory.

It works! Thank you.
