Description

Files:

opencode-installation-issue-report.md
opencode-fix-documentation.md
Summary: OpenCode v1.1.13 installation appears successful but the tool is completely non-functional due to Bun runtime virtual filesystem (bunfs) incompatibility with PRoot environments.

Key Issues:

UX Issue: Installation script doesn't update current shell PATH (easily worked around with source ~/.bashrc)
Critical Bug: Bun's bunfs cannot resolve module paths in PRoot, causing all core commands to fail
Error:

Error: Cannot find module '/home/arnab/.cache/opencode/node_modules/opencode-copilot-auth'
from '/$bunfs/root/src/index.js'
Working Commands: --version, --help, models, debug paths Broken Commands: run, stats, debug config (anything that loads plugins)

Severity: CRITICAL - Tool is completely unusable on this platform

Root Cause: Bun's virtual filesystem (bunfs) is incompatible with PRoot's user-space virtualization layer

Recommended Fixes:

Detect PRoot/container environments and use Node.js runtime instead of Bun
Disable bunfs via BUN_DISABLE_BUNFS=1 environment variable
Use absolute filesystem paths instead of Bun virtual paths
Add platform compatibility warnings at install time
Status: No user workaround available - Requires OpenCode team to implement PRoot compatibility

This issue might be a duplicate of existing issues. Please check:

  • #7843: [Critical] CLI hangs on second run (Deadlock) on Linux ARM64 (Proot/Container environments) - Reports identical Proot/ARM64 environment issues with CLI hangs on second run
  • #7472: OpenCode crashes with "Aborted" on Termux/Debian on second attempt - Reports crashes on second run in Termux/Proot environments
  • #3143: [Bug] Opencode crashes on second run in Termux/Proot distro - Reports crashes on subsequent runs in Proot distros
  • #6825: [FEATURE]:Provide a package without native binary, for running with nodejs - Feature request for Node.js runtime to avoid Bun/bunfs incompatibility in PRoot environments

Feel free to ignore if your specific case differs from these, but these issues address Bun runtime and Proot/Termux compatibility concerns.
