Installation¶

Platform-specific guides¶

Platform	One-liner	Detailed guide
macOS	`curl -fsSL https://open-jarvis.github.io/OpenJarvis/install.sh \\| bash`	macOS install
Linux	`curl -fsSL https://open-jarvis.github.io/OpenJarvis/install.sh \\| bash`	Linux install
WSL2 on Windows	`curl -fsSL https://open-jarvis.github.io/OpenJarvis/install.sh \\| bash` (run inside Ubuntu)	WSL2 install
Native Windows	`irm https://open-jarvis.github.io/OpenJarvis/install.ps1 \\| iex`	Native Windows install
Desktop GUI	Download from the latest release	—

The bash and PowerShell installers do the same thing on their respective hosts. The rest of this page documents the bash installer in detail; the native Windows guide is the equivalent reference for PowerShell.

Bash installer¶

curl -fsSL https://open-jarvis.github.io/OpenJarvis/install.sh | bash

The installer downloads everything for you — including uv (the Python package manager), the Python venv, Ollama, and a small starter model. You don't need to install uv or any other prerequisite first.

Install URL

This script is served straight from the project's own GitHub Pages site, so HTTPS always works. You may also see https://openjarvis.ai/install.sh referenced in older docs — that domain is community-operated and has had intermittent TLS issues (#337). The open-jarvis.github.io URL above is the canonical one.

About 3 minutes on a typical broadband connection. Type jarvis to start chatting.

What the installer does¶

Phase	Step	Where
Foreground	Install `uv` (Python package manager)	`~/.cargo/bin/` or `~/.local/bin/`
Foreground	Clone OpenJarvis repo	`~/.openjarvis/src/`
Foreground	Create Python 3.11 venv	`~/.openjarvis/.venv/`
Foreground	`uv pip install -e .` (editable install)	venv
Foreground	Install Ollama	system default
Foreground	Start `ollama serve`	systemd-user / launchd / nohup
Foreground	Pull `qwen3.5:2b` (~1.5 GB)	Ollama's model store
Foreground	Write `config.toml` (auto-detected hardware + engine + model)	`~/.openjarvis/config.toml`
Foreground	Symlink `jarvis` and `jarvis-uninstall`	`~/.local/bin/`
Foreground	Add `~/.local/bin` to PATH if missing (with on-screen notice)	`~/.bashrc` or `~/.zshrc`
Background	Install Rust toolchain via rustup	`~/.cargo/`
Background	Build the maturin extension (memory + security features)	venv
Background	Pull hardware-tier and tier+1 models	Ollama's model store

What the installer does NOT touch¶

Your existing Python installations
Your ~/.bashrc / ~/.zshrc other than appending one PATH line (with on-screen notice)
Your existing Ollama models
Any other tool or dotfile

Idempotent re-runs¶

Re-running the curl line is safe. The installer reads ~/.openjarvis/.state/install-state.json and skips completed steps. If your venv got nuked, re-running heals it.

Cloud quick-path¶

If any of these env vars are set when you install or run jarvis init, the installer/init proposes cloud as the default and writes the matching provider into config.toml:

OPENROUTER_API_KEY
ANTHROPIC_API_KEY
OPENAI_API_KEY
GOOGLE_API_KEY (or GEMINI_API_KEY)

Local-first remains the default when no key is in env. Precedence is OpenRouter > Anthropic > OpenAI > Google.

Flags¶

Flag	Effect
`--minimal`	Skip the foreground model pull. First chat will need to wait for the bg pull to finish.
`--no-bg-orchestrator`	Don't detach the background work pipeline. (Mostly for testing.)
`--force`	Re-run all steps even if `install-state.json` says they're done.

Environment overrides¶

Variable	Default	Purpose
`OPENJARVIS_HOME`	`$HOME/.openjarvis`	Install location.
`OPENJARVIS_REPO_URL`	`https://github.com/open-jarvis/OpenJarvis.git`	Source repo for the clone step.

Uninstall¶

jarvis-uninstall

Removes ~/.openjarvis/, ~/.local/bin/jarvis, and ~/.local/bin/jarvis-uninstall. Leaves Ollama, uv, and the Rust toolchain in place (they may be used by other tools); the script prints removal hints.

Updating¶

jarvis update

Pulls the latest source, refreshes the editable install, and rebuilds the Rust extension in the background. Models are not touched.

Troubleshooting¶

"command not found: jarvis"¶

~/.local/bin isn't on your PATH. Run source ~/.bashrc (or ~/.zshrc) or open a new terminal.

"memory features unavailable"¶

Rust extension hasn't finished building yet (or failed). Check status:

jarvis doctor

Manually retry:

~/.openjarvis/.scripts/install-rust.sh && ~/.openjarvis/.scripts/build-extension.sh

A bigger model failed to download¶

Check status and retry:

jarvis doctor
~/.openjarvis/.scripts/pull-model.sh qwen3.5:9b

Behind a corporate proxy¶

Set HTTPS_PROXY and CURL_CA_BUNDLE in your environment before running the installer.
