Troubleshooting & FAQ

Common issues when using the OpenCode Walkthrough extension with the integrated terminal and environment variables.

On this page

Quick diagnosis

Run these in order:

  1. Command Palette → OpenCode: Show Actions — confirms the extension activated.

  2. Open a terminal in VS Code and run:

    opencode --version
opencode auth ls

  3. Run OpenCode: Check Health to confirm auth/install status.

Header / symptom Likely cause Jump to
OpenCode CLI is not installed opencode not on PATH Install & PATH
no providers configured Auth not set up Matrix: Auth
Command runs but env ignored Manual terminal vs extension dispatch Environment variables
curl | bash fails on Windows Wrong install method Install & PATH
Untrusted workspace warning Workspace trust off Matrix: Trust

Troubleshooting matrix

Symptom Probable cause Fix
opencode: command not found in VS Code terminal Install dir not on PATH; terminal started before install Add install dir to PATH; restart VS Code; see PATH
Extension health OK but terminal says not found Different shell profile (Git Bash vs PowerShell) Set Terminal › Integrated › Default Profile; open new terminal
curl -fsSL … | bash fails on Windows Bash pipe not available in default shell Use npm install -g opencode-ai or opencode.ai/download
Installed with npm but opencode missing Global npm bin not on PATH npm config get prefix → add \bin (Windows) or /bin (Unix) to PATH
$OPENCODE_INSTALL_DIR / custom install path CLI installed outside default location Export OPENCODE_INSTALL_DIR or add $OPENCODE_INSTALL_DIR/bin to PATH in shell profile
Settings opencode.serverUsername ignored in manual terminal Env only prefixed by extension Run via extension command, or export var yourself
PowerShell shows export: term not recognized Unix syntax in PowerShell Use extension commands (auto $env:VAR=) or set $env:OPENCODE_* manually
Semicolon command chain fails in cmd.exe cmd ≠ PowerShell Set default profile to PowerShell or Git Bash
no providers configured No opencode auth login OpenCode: Auth Login or opencode auth login
Port 4096 already in use Another opencode serve running Kill old server or pick a different port
Sessions tree empty No sessions yet or stale cache Run a prompt; Refresh on Sessions toolbar
Wiki push: repository not found Wiki never initialized in browser npm run wiki:init then npm run wiki:push

Environment variables

The extension maps VS Code settings under opencode.* to OPENCODE_* variables (see lib/env.js). They are applied in two ways:

Mechanism When it applies
buildTerminalCommand() OpenCode: Install, Run Inline, Start Interactive, serve, etc. — prepends $env:VAR="…"; (Windows) or export VAR="…" && (Unix)
buildEnvObject() Health checks — child process env

Mapped settings (reference)

VS Code setting Environment variable
opencode.configPath OPENCODE_CONFIG
opencode.configDir OPENCODE_CONFIG_DIR
opencode.tuiConfigPath OPENCODE_TUI_CONFIG
opencode.autoShare OPENCODE_AUTO_SHARE
opencode.experimental.planMode OPENCODE_EXPERIMENTAL_PLAN_MODE
opencode.experimental.backgroundSubagents OPENCODE_EXPERIMENTAL_BACKGROUND_SUBAGENTS
opencode.serverUsername / serverPassword OPENCODE_SERVER_USERNAME / OPENCODE_SERVER_PASSWORD
(full list) See package.json → configuration.properties

FAQ: Why is my env var missing?

Q: I set opencode.configPath but echo $OPENCODE_CONFIG is empty in a terminal I opened myself.

A: Extension-injected env applies only to commands sent through sendToTerminal() or harness spawns. For a manual terminal session, add the export to your shell profile or run the extension command again in that terminal.

Q: Does the extension set OPENCODE_INSTALL_DIR?

A: No. That variable comes from the OpenCode install script when it installs outside standard paths. If the CLI works in a login shell but not in VS Code, add the install bin directory to PATH in your user environment and restart VS Code.

Q: Boolean settings show as "true" / "false" strings.

A: Expected — the CLI reads string env values.

Q: Values with quotes break my PowerShell command.

A: The extension escapes embedded " in values. Avoid unescaped quotes in settings.

Terminal & shell issues

How the extension builds terminal lines

Windows (PowerShell):  $env:OPENCODE_FOO="bar"; opencode run "prompt"
Unix (bash/zsh):       export OPENCODE_FOO="bar" && opencode run "prompt"

Platform is detected at extension runtime (process.platform), not from your terminal profile. If VS Code's default profile is PowerShell but you switched a tab to Git Bash, env syntax from a previous extension command may not match the active shell — open a fresh terminal or align your default profile.

Recommended terminal profiles

OS Recommended default Install command
Windows PowerShell npm install -g opencode-ai
macOS / Linux bash or zsh curl -fsSL https://opencode.ai/install | bash

Reusing the OpenCode terminal

sendToTerminal() reuses vscode.window.activeTerminal or creates one named OpenCode. Stale env from an old session is rare because each send prepends fresh exports; if commands behave oddly, kill the terminal tab and rerun the extension command.

OpenCode Server terminal

Run OpenCode: Start Server to open a terminal running opencode serve.

Install & PATH

Windows

  1. npm install -g opencode-ai (no sudo).
  2. Verify: opencode --version in the same terminal profile VS Code uses.
  3. If not found: add %APPDATA%\npm (or npm config get prefix`\bin`) to user PATH.
  4. Reload VS Code window.

macOS / Linux

  1. Install script or npm install -g opencode-ai.
  2. Install script may print a path — add to ~/.bashrc, ~/.zshrc, or ~/.profile.
  3. If using OPENCODE_INSTALL_DIR, ensure $OPENCODE_INSTALL_DIR/bin is on PATH.

Extension install command

OpenCode: Install CLI runs the platform-appropriate command with env prefixes. On Windows it runs npm install -g opencode-ai, not curl | bash.

Wiki & CI sync

Error Fix
Wiki git repository is not provisioned yet Open wiki _new, save Home once, retry npm run wiki:push
wiki:init needed npm run wiki:init (browser sign-in)
CI Sync Wiki failed Ensure docs/** committed; workflow runs on push to master

Still stuck?

  1. Open an issue with:
    • OS and VS Code version
    • Default terminal profile
    • Output of opencode --version and opencode auth ls (redact secrets)
  2. CLI reference: opencode.ai/docs
