That's expected - if you see in your screenshot, it prints a list of the available versions. There is no 3.12.1. You probably want to install 3.12.0 then.

I'm going to close this but feel free to reply if you're confused or need more help

Thanks for your reply
I have some problems with #4230
It fixed my problem and I checked it should be in the 3.12.1 version
Anyway, I can't install versions in the npm and yarn because of nodejs version
Is there anyway to build and run the code-server from main branch (source in GitHub)?

Sorry, we changed some things and never released 3.12.1. But we're releasing 4.0.0 very soon.

You could, but it might be easier to download a release from the releases page under Assets here. Follow the docs here. Let me know if that works!

Sadly, Based on this link:
https://wiki.termux.com/wiki/Differences_from_Linux#Termux_uses_Bionic_libc
I can't run any pre-compiled binaries
Only I can install ones with configs and patches for termux
Even I tried to run node v14 using tarball with no results
Sadly, It looks like I can't have code-server in my Android device for now

@amiria703 shoot :(

Can you try this approach?

@jsjoeio
Solved!
Using this command to install it:
apt update && apt upgrade && apt install python binutils && env FORCE_NODE_VERSION=16 yarn global add code-server --ignore-engines

Hooray! thanks for sharing!
