[wonichan]

same with me...

[Henry-G-H-Huang]

for my workaround, fix the version in plugin config and disable the auto-check-update hook, it should keep you in 2.14.0 version. And everything is fine..

[bodzebod]

same error for me

[MCshin00]

Try this (based on #1072 (comment)). I updated it with Codex (xhigh), and it worked for me.

Hope this works for everyone.

maybe can wait for issue #1171 finished

[luqingjia]

open the opencode cli and paste this "Install and configure oh-my-opencode by following the instructions here:
https://raw.githubusercontent.com/code-yeongyu/oh-my-opencode/refs/heads/master/docs/guide/installation.md" on the input box

[bodzebod]

@luqingjia you misunderstand the issue. We all have run the installation, but the windows binary of release 3.1.2 is failing to execute. This is not an installation procedure problem, this is a release issue.

The temporary workaround proposed by @nunch-dev , to install release 3.1.0, worked for me: bunx oh-my-opencode@3.1.0 install
