OpenClaw ships three installer scripts, served from `openclaw.ai`.
| Script | Platform | What it does |
| ---------------------------------- | -------------------- | -------------------------------------------------------------------------------------------------------------- |
| [`install.sh`](#installsh) | macOS / Linux / WSL | Installs Node if needed, installs OpenClaw via npm (default) or git, and can run onboarding. |
| [`install-cli.sh`](#install-clish) | macOS / Linux / WSL | Installs Node + OpenClaw into a local prefix (`~/.openclaw`) with npm or git checkout modes. No root required. |
| [`install.ps1`](#installps1) | 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).
Checks Node version and installs Node 24 if needed (Homebrew on macOS, NodeSource setup scripts on Linux apt/dnf/yum). On macOS, Homebrew is installed only when the installer needs it for Node or Git. OpenClaw still supports Node 22 LTS, currently `22.19+`, for compatibility.
On Alpine/musl Linux, the installer uses apk packages instead of NodeSource; the configured Alpine repositories must provide Node `22.19+` (Alpine 3.21 or newer at the time of writing).
Installs Git if missing using the detected package manager, including Homebrew on macOS and apk on Alpine.
- `npm` method (default): global npm install
- `git` method: clone/update repo, install deps with pnpm, build, then install wrapper at `~/.local/bin/openclaw`
- Refreshes a loaded gateway service best-effort (`openclaw gateway install --force`, then restart)
- 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)
### 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

## install-cli.sh
Designed for environments where you want everything under a local prefix
(default `~/.openclaw`) and no system Node dependency. Supports npm installs
by default, plus git-checkout installs under the same prefix flow.
### Flow (install-cli.sh)
Downloads a pinned supported Node LTS tarball (the version is embedded in the script and updated independently) to `/tools/node-v` and verifies SHA-256.
On Alpine/musl Linux, where Node does not publish compatible tarballs for the pinned runtime, installs `nodejs` and `npm` with `apk` and links that runtime into the prefix wrapper path. The Alpine repositories must provide Node `22.19+`; use Alpine 3.21 or newer if older repositories only provide Node 20 or 21.
If Git is missing, attempts install via apt/dnf/yum/apk on Linux or Homebrew on macOS.
- `npm` method (default): installs under the prefix with npm, then writes wrapper to `/bin/openclaw`
- `git` method: clones/updates a checkout (default `~/openclaw`) and still writes the wrapper to `/bin/openclaw`
If a gateway service is already loaded from that same prefix, the script runs
`openclaw gateway install --force`, then `openclaw gateway restart`, and
probes gateway health best-effort.
### 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

## install.ps1
### Flow (install.ps1)
Requires PowerShell 5+.
If missing, attempts install via winget, then Chocolatey, then Scoop. If no package manager is available, the script downloads the official Node.js Windows zip into `%LOCALAPPDATA%\OpenClaw\deps\portable-node` and adds it to the current process and user PATH. Node 22 LTS, currently `22.19+`, remains supported for compatibility.
- `npm` method (default): global npm install using selected `-Tag`, launched from a writable installer temp directory so shells opened in protected folders such as `C:\` still work
- `git` method: clone/update repo, install/build with pnpm, and install wrapper at `%USERPROFILE%\.local\bin\openclaw.cmd`. If Git is missing, the script bootstraps user-local MinGit under `%LOCALAPPDATA%\OpenClaw\deps\portable-git` and adds it to the current process and user PATH.
- Adds needed bin directory to user PATH when possible
- Refreshes a loaded gateway service best-effort (`openclaw gateway install --force`, then restart)
- Runs `openclaw doctor --non-interactive` on upgrades and git installs (best effort)
`iwr ... | iex` and scriptblock installs report a terminating error without closing the current PowerShell session. Direct `powershell -File` / `pwsh -File` installs still exit non-zero for automation.
### 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 -Tag main
```
```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
```
```powershell
# install.ps1 has no dedicated -Verbose flag yet.
Set-PSDebug -Trace 1
& ([scriptblock]::Create((iwr -useb https://openclaw.ai/install.ps1))) -NoOnboard
Set-PSDebug -Trace 0
```
| Flag | Description |
| --------------------------- | ---------------------------------------------------------- |
| `-InstallMethod npm\|git` | Install method (default: `npm`) |
| `-Tag ` | npm dist-tag, version, or package spec (default: `latest`) |
| `-GitDir ` | 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=` | 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 tries a user-local MinGit bootstrap before printing 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).
Rerun the installer so it can bootstrap user-local MinGit, or install Git for Windows and reopen PowerShell.
Run `npm config get prefix` and add that directory to your user PATH (no `\bin` suffix needed on Windows), then reopen PowerShell.
`install.ps1` does not currently expose a `-Verbose` switch.
Use PowerShell tracing for script-level diagnostics:
```powershell
Set-PSDebug -Trace 1
& ([scriptblock]::Create((iwr -useb https://openclaw.ai/install.ps1))) -NoOnboard
Set-PSDebug -Trace 0
```
Usually a PATH issue. See [Node.js troubleshooting](/install/node#troubleshooting).
