# Installer Internals

# Installer internals

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

| Script                       | Platform             | What it does                                                                                                       |
| ---------------------------- | -------------------- | ------------------------------------------------------------------------------------------------------------------ |
| [`install.sh`](#installsh)   | macOS / Linux / WSL  | Installs Node if needed, installs the `wednesdayai` npm package (default) or git checkout, and can run onboarding. |
| [`install.ps1`](#installps1) | Windows (PowerShell) | Installs Node if needed, installs the `wednesdayai` npm package (default) or git checkout, and can run onboarding. |

## Quick commands

## install.sh

<Tip>
  Recommended for most interactive installs on macOS/Linux/WSL.
</Tip>

### Flow (install.sh)

<Steps>
  <Step title="Detect OS">
    Supports macOS and Linux (including WSL). If macOS is detected, installs Homebrew if missing.
  </Step>

  <Step title="Ensure Node.js 24+">
    Checks Node version and installs Node 24 if needed (Homebrew on macOS, NodeSource setup scripts on Linux apt/dnf/yum).
  </Step>

  <Step title="Ensure Git">
    Installs Git if missing.
  </Step>

  <Step title="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`
  </Step>

  <Step title="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`
  </Step>
</Steps>

### 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.

## Troubleshooting

<AccordionGroup>
  <Accordion title="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.
  </Accordion>

  <Accordion title="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).
  </Accordion>

  <Accordion title="sharp/libvips issues">
    The scripts default `SHARP_IGNORE_GLOBAL_LIBVIPS=1` to avoid sharp building against system libvips. To override:

    ```bash theme={"dark"}
    SHARP_IGNORE_GLOBAL_LIBVIPS=0 curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash
    ```
  </Accordion>

  <Accordion title="Windows: &#x22;npm error spawn git / ENOENT&#x22;">
    Install Git for Windows, reopen PowerShell, rerun installer.
  </Accordion>

  <Accordion title="Windows: &#x22;openclaw is not recognized&#x22;">
    Run `npm config get prefix` and add that directory to your user PATH (no `\bin` suffix needed on Windows), then reopen PowerShell.
  </Accordion>

  <Accordion title="Windows: how to get verbose installer output">
    `install.ps1` does not currently expose a `-Verbose` switch.
    Use PowerShell tracing for script-level diagnostics:

    ```powershell theme={"dark"}
    Set-PSDebug -Trace 1
    & ([scriptblock]::Create((iwr -useb https://openclaw.ai/install.ps1))) -NoOnboard
    Set-PSDebug -Trace 0
    ```
  </Accordion>

  <Accordion title="openclaw not found after install">
    Usually a PATH issue. See [Node.js troubleshooting](/install/node#troubleshooting).
