Installer internals

WednesdayAI ships two installer scripts, served from openclaw.ai.

Script	Platform	What it does
`install.sh`	macOS / Linux / WSL	Installs Node if needed, installs the `wednesdayai` npm package (default) or git checkout, and can run onboarding.
`install.ps1`	Windows (PowerShell)	Installs Node if needed, installs the `wednesdayai` npm package (default) or git checkout, and can run onboarding.

Quick commands

install.sh
install.ps1

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

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

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

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

If install succeeds but neither wednesdayai nor the compatibility openclaw command is found in a new terminal, see Node.js troubleshooting.

install.sh

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

Flow (install.sh)

Detect OS

Supports macOS and Linux (including WSL). If macOS is detected, installs Homebrew if missing.

Ensure Node.js 24+

Checks Node version and installs Node 24 if needed (Homebrew on macOS, NodeSource setup scripts on Linux apt/dnf/yum).

Ensure Git

Installs Git if missing.

Install WednesdayAI

npm method (default): global npm install of wednesdayai@<version-or-tag>
git method: clone/update repo, install deps with pnpm, build, then install wrapper at ~/.local/bin/openclaw

Post-install tasks

Runs openclaw doctor --non-interactive on upgrades and git installs (best effort). openclaw remains a compatibility binary for the same install.
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 a WednesdayAI 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)

Default
Skip onboarding
Git install
Dry run

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

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

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

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

`OPENCLAW_NPM_LOGLEVEL=error\|warn\|notice`	npm log level
`SHARP_IGNORE_GLOBAL_LIBVIPS=0\|1`	Control sharp/libvips behavior (default: `1`)

install.ps1

Flow (install.ps1)

Ensure PowerShell + Windows environment

Requires PowerShell 5+.

Ensure Node.js 24+

If missing, attempts install via winget, then Chocolatey, then Scoop.

Install WednesdayAI

npm method (default): global npm install of wednesdayai@<tag>
git method: clone/update repo, install/build with pnpm, and install wrapper at %USERPROFILE%\.local\bin\openclaw.cmd

Post-install tasks

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)

Default
Git install
Custom git directory
Dry run
Debug trace

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

& ([scriptblock]::Create((iwr -useb https://openclaw.ai/install.ps1))) -InstallMethod git

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

& ([scriptblock]::Create((iwr -useb https://openclaw.ai/install.ps1))) -DryRun

# 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

Flags reference

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

Environment variables reference

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.

install.sh (non-interactive npm)
install.sh (non-interactive git)
install.ps1 (skip onboarding)

curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash -s -- --no-prompt --no-onboard

OPENCLAW_INSTALL_METHOD=git OPENCLAW_NO_PROMPT=1 \
  curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash

& ([scriptblock]::Create((iwr -useb https://openclaw.ai/install.ps1))) -NoOnboard

Troubleshooting

Why is Git required?

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.

Why does npm hit EACCES on Linux?

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).

sharp/libvips issues

The scripts default SHARP_IGNORE_GLOBAL_LIBVIPS=1 to avoid sharp building against system libvips. To override:

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

Windows: "npm error spawn git / ENOENT"

Install Git for Windows, reopen PowerShell, rerun installer.

Windows: "openclaw is not recognized"

Run npm config get prefix and add that directory to your user PATH (no \bin suffix needed on Windows), then reopen PowerShell.

Windows: how to get verbose installer output

install.ps1 does not currently expose a -Verbose switch. Use PowerShell tracing for script-level diagnostics:

Set-PSDebug -Trace 1
& ([scriptblock]::Create((iwr -useb https://openclaw.ai/install.ps1))) -NoOnboard
Set-PSDebug -Trace 0

openclaw not found after install

Usually a PATH issue. See Node.js troubleshooting.
