Start Here: Run OpenClaw Doctor
Before diving into manual troubleshooting, run:
openclaw doctor --fix
This automatically checks Node.js version, Docker status, API key configuration, port availability, and missing directories. According to the official troubleshooting guide, this command resolves 60% of installation issues automatically.
If that doesn't work, continue below.
Error #1: Node.js Version Incompatibility
Error message:
OpenClaw requires Node.js 22 or newer
Why it happens: OpenClaw uses JavaScript APIs introduced in Node 22. Node 18 and 20 LTS are not supported — even though they're widely installed as "stable" versions.
Fix:
# Check your current version
node --version
# If it shows v18.x.x or v20.x.x, upgrade with nvm:
nvm install 22
nvm use 22
nvm alias default 22 # Make 22 your default
node --version # Should now show v22.x.x
Error #2: Sharp Dependency Build Failure
Error message:
[email protected] failed to build from source
Please add node-gyp to your dependencies
Why it happens: On macOS with Node 22.22.0+, npm tries to compile the sharp image library from source. The build fails because node-gyp isn't available in the install context.
Fix:
# Option 1: Use pnpm instead (recommended)
npm install -g pnpm
pnpm install -g openclaw
# Option 2: Install node-gyp globally first
npm install -g node-gyp
npm install -g openclaw
# Option 3: Use a slightly older Node 22 build
nvm install 22.0.0
nvm use 22.0.0
npm install -g openclaw
Error #3: "openclaw: command not found"
Error message:
bash: openclaw: command not found
Why it happens: npm installed OpenClaw successfully, but your shell can't find the binary because npm's global bin directory isn't in your PATH.
Fix:
# Find npm's global binary location
npm config get prefix
# Typical output: /usr/local or /home/user/.npm-global
# Add it to PATH (add to ~/.bashrc or ~/.zshrc)
export PATH="$PATH:$(npm config get prefix)/bin"
# Apply immediately
source ~/.bashrc # or source ~/.zshrc
Error #4: Port 18789 Already in Use
Error message:
address already in use :::18789
Why it happens: Another process — often a previous OpenClaw instance that didn't fully shut down — is occupying the default gateway port.
Fix:
# Find what's using the port
lsof -i :18789
# Kill the process (replace 12345 with the actual PID)
kill -9 12345
# Restart OpenClaw
openclaw start
# Alternative: change OpenClaw's port
openclaw config set gateway.port 18790
Error #5: npm install Failed (pnpm Required)
Error message:
npm install failed; dependency resolution error
Why it happens: OpenClaw's monorepo uses pnpm workspaces, which npm can't resolve correctly.
Fix:
npm install -g pnpm
# Build from source with pnpm
git clone https://github.com/openclaw/openclaw.git
cd openclaw
pnpm install
pnpm build
Error #6: Docker Volume Mount Issues
Error message:
Error response from daemon: invalid mount config
Why it happens: Path syntax differs between Windows, macOS, and Linux. Windows paths like C:\Users\... are invalid inside Docker.
Fix for Windows WSL2:
# Use the WSL path format:
docker run -v /mnt/c/Users/YourName/openclaw:/data openclaw
# NOT: C:\Users\YourName\openclaw
Error #7: Gateway Authentication Failed
Error message:
RPC probe: failed - authentication error
Why it happens: Missing or invalid API key for the AI provider.
Fix:
# Set your Anthropic API key
export ANTHROPIC_API_KEY=sk-ant-your-key-here
# Or configure permanently via config
openclaw config set providers.anthropic.apiKey "sk-ant-your-key-here"
# Restart the gateway
openclaw gateway restart
When to Stop Troubleshooting
Every error above is fixable. But there's a threshold question worth asking: is debugging installation errors the best use of your time right now?
If you've spent more than 30 minutes on installation and still don't have a working agent, managed hosting is almost certainly the better option. Not because self-hosting is bad — it's a legitimate approach for the right situation — but because your goal was to use OpenClaw, not to become proficient at debugging Node.js build systems.
NeatClaw eliminates every error on this page:
| Error | With Self-Hosting | With NeatClaw |
|---|---|---|
| Node.js version | Debug and upgrade | Not possible |
| Sharp dependency | Rebuild or workaround | Not possible |
| Command not found | Fix PATH | Not possible |
| Port conflicts | Debug | Not possible |
| Docker issues | Troubleshoot | Not possible |
| Auth errors | Configure manually | Guided setup |
