Description

When I use opencode on NFS, bun install has hardlink/symlink-related filesystem compatibility issues, which causes some packages to fail to install correctly, resulting in opencode not functioning properly.

You can modify below code to resolve this issue.

modify bunfig.toml as below
[install]
exact = true
backend = "copyfile"

modify packages/opencode/src/bun/index.ts as below
const args = ["add", "--force", "--exact", "--backend=copyfile", "--cwd", Global.Path.cache, pkg + "@" + version]

OpenCode version

latest

Steps to reproduce

  1. use opencode in the NFS

Screenshot and/or share link

Operating System

ubuntu 24

Terminal

VScode remoteSSH

Could you fix this issue?

    I have the same issue. My opencode keep failing with BunInstallFailedError on a NFS server.

    With the following error messages found in log

    FileNotFound: failed copying files from cache to destination for package mime-types
<similiar error for other packages>

    My workaround is moving BUN's global cache to local storage by

    export BUN_INSTALL_CACHE_DIR="<a local storage location instead of NFS>"

    If it doesn't work, also move your opencode config and cache directory to local storage and make a soft link to your home

    # Create the symlinks
ln -s <local storage>/opencode/cache ~/.cache/opencode
ln -s <local storage>/opencode/config ~/.config/opencode
