Installer internals

OpenClaw ships three installer scripts, served from openclaw.ai.

Script	Platform	What it does
install.sh	macOS / Linux / WSL	Installs Node if needed, installs OpenClaw via npm (default) or git, and can run onboarding.
install-cli.sh	macOS / Linux / WSL	Installs Node + OpenClaw into a local prefix (~/.openclaw). No root required.
install.ps1	Windows (PowerShell)	Installs Node if needed, installs OpenClaw via npm (default) or git, and can run onboarding.

Quick commands

```bash curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash ```

```bash
curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash -s -- --help
```

```bash curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install-cli.sh | bash ```

```bash
curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install-cli.sh | bash -s -- --help
```

```powershell iwr -useb https://openclaw.ai/install.ps1 | iex ```

```powershell
& ([scriptblock]::Create((iwr -useb https://openclaw.ai/install.ps1))) -Tag beta -NoOnboard -DryRun
```

If install succeeds but `openclaw` is not found in a new terminal, see [Node.js troubleshooting](/install/node#troubleshooting).

install.sh

Recommended for most interactive installs on macOS/Linux/WSL.

Flow (install.sh)

Supports macOS and Linux (including WSL). If macOS is detected, installs Homebrew if missing. Checks Node version and installs Node 22 if needed (Homebrew on macOS, NodeSource setup scripts on Linux apt/dnf/yum). Installs Git if missing. - `npm` method (default): global npm install - `git` method: clone/update repo, install deps with pnpm, build, then install wrapper at `~/.local/bin/openclaw` - Runs `openclaw doctor --non-interactive` on upgrades and git installs (best effort) - Attempts onboarding when appropriate (TTY available, onboarding not disabled, and bootstrap/config checks pass) - Defaults `SHARP_IGNORE_GLOBAL_LIBVIPS=1`

Source checkout detection

If run inside an OpenClaw checkout (package.json + pnpm-workspace.yaml), the script offers:

• use checkout (git), or
• use global install (npm)

If no TTY is available and no install method is set, it defaults to npm and warns.

The script exits with code 2 for invalid method selection or invalid --install-method values.

Examples (install.sh)

```bash curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash ``` ```bash curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash -s -- --no-onboard ``` ```bash curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash -s -- --install-method git ``` ```bash curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash -s -- --dry-run ```

---

install-cli.sh

Designed for environments where you want everything under a local prefix (default `~/.openclaw`) and no system Node dependency.

Flow (install-cli.sh)

Downloads Node tarball (default `22.22.0`) to `/tools/node-v` and verifies SHA-256. If Git is missing, attempts install via apt/dnf/yum on Linux or Homebrew on macOS. Installs with npm using `--prefix `, then writes wrapper to `/bin/openclaw`.

Examples (install-cli.sh)

```bash curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install-cli.sh | bash ``` ```bash curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install-cli.sh | bash -s -- --prefix /opt/openclaw --version latest ``` ```bash curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install-cli.sh | bash -s -- --json --prefix /opt/openclaw ``` ```bash curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install-cli.sh | bash -s -- --onboard ```

Flag	Description
--prefix <path>	Install prefix (default: ~/.openclaw)
--version <ver>	OpenClaw version or dist-tag (default: latest)
--node-version <ver>	Node version (default: 22.22.0)
--json	Emit NDJSON events
--onboard	Run openclaw onboard after install
--no-onboard	Skip onboarding (default)
--set-npm-prefix	On Linux, force npm prefix to ~/.npm-global if current prefix is not writable
--help	Show usage (-h)

Variable	Description
OPENCLAW_PREFIX=<path>	Install prefix
OPENCLAW_VERSION=<ver>	OpenClaw version or dist-tag
OPENCLAW_NODE_VERSION=<ver>	Node version
OPENCLAW_NO_ONBOARD=1	Skip onboarding
OPENCLAW_NPM_LOGLEVEL=error|warn|notice	npm log level
OPENCLAW_GIT_DIR=<path>	Legacy cleanup lookup path (used when removing old Peekaboo submodule checkout)
SHARP_IGNORE_GLOBAL_LIBVIPS=0|1	Control sharp/libvips behavior (default: 1)

install.ps1

Flow (install.ps1)

Requires PowerShell 5+. If missing, attempts install via winget, then Chocolatey, then Scoop. - `npm` method (default): global npm install using selected `-Tag` - `git` method: clone/update repo, install/build with pnpm, and install wrapper at `%USERPROFILE%\.local\bin\openclaw.cmd` Adds needed bin directory to user PATH when possible, then runs `openclaw doctor --non-interactive` on upgrades and git installs (best effort).

Examples (install.ps1)

```powershell iwr -useb https://openclaw.ai/install.ps1 | iex ``` ```powershell & ([scriptblock]::Create((iwr -useb https://openclaw.ai/install.ps1))) -InstallMethod git ``` ```powershell & ([scriptblock]::Create((iwr -useb https://openclaw.ai/install.ps1))) -InstallMethod git -GitDir "C:\openclaw" ``` ```powershell & ([scriptblock]::Create((iwr -useb https://openclaw.ai/install.ps1))) -DryRun ```

Flag	Description
-InstallMethod npm|git	Install method (default: npm)
-Tag <tag>	npm dist-tag (default: latest)
-GitDir <path>	Checkout directory (default: %USERPROFILE%\openclaw)
-NoOnboard	Skip onboarding
-NoGitUpdate	Skip git pull
-DryRun	Print actions only

Variable	Description
OPENCLAW_INSTALL_METHOD=git|npm	Install method
OPENCLAW_GIT_DIR=<path>	Checkout directory
OPENCLAW_NO_ONBOARD=1	Skip onboarding
OPENCLAW_GIT_UPDATE=0	Disable git pull
OPENCLAW_DRY_RUN=1	Dry run mode

If `-InstallMethod git` is used and Git is missing, the script exits and prints the Git for Windows link.

CI and automation

Use non-interactive flags/env vars for predictable runs.

```bash curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash -s -- --no-prompt --no-onboard ``` ```bash OPENCLAW_INSTALL_METHOD=git OPENCLAW_NO_PROMPT=1 \ curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash ``` ```bash curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install-cli.sh | bash -s -- --json --prefix /opt/openclaw ``` ```powershell & ([scriptblock]::Create((iwr -useb https://openclaw.ai/install.ps1))) -NoOnboard ```

Troubleshooting

Git is required for `git` install method. For `npm` installs, Git is still checked/installed to avoid `spawn git ENOENT` failures when dependencies use git URLs. Some Linux setups point npm global prefix to root-owned paths. `install.sh` can switch prefix to `~/.npm-global` and append PATH exports to shell rc files (when those files exist). The scripts default `SHARP_IGNORE_GLOBAL_LIBVIPS=1` to avoid sharp building against system libvips. To override:

```bash
SHARP_IGNORE_GLOBAL_LIBVIPS=0 curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash
```

Install Git for Windows, reopen PowerShell, rerun installer. Run `npm config get prefix`, append `\bin`, add that directory to user PATH, then reopen PowerShell. Usually a PATH issue. See [Node.js troubleshooting](/install/node#troubleshooting).
