# OpenClaw Installer - Final Fixes Summary

## ✅ ALL ISSUES RESOLVED

### What Was Fixed

#### 1. **Node.js Version Compatibility** ✅
- **Problem**: System Node.js v22.12.0 has broken npm; OpenClaw requires v22.16.0+
- **Solution**: Updated `NODE_VERSION = "22.16.0"`
- **File**: `openclaw_installer/installer.py:14`

#### 2. **Automatic Node.js Download Fallback** ✅
- **Problem**: When system npm fails, installation would fail
- **Solution**: On npm failure, automatically downloads Node.js v22.16.0 and retries
- **Implementation**: `_install_openclaw()` with 3 attempts and exponential backoff
- **Files**: `openclaw_installer/installer.py:296-431`

#### 3. **Correct Wrapper Creation** ✅
- **Problem**: Wrapper pointed to system Node.js instead of downloaded Node.js
- **Solution**: 
  - Added `install_method: "global"` tracking
  - Updated `_get_openclaw_path()` to use correct Node.js/npm paths
  - Fixed PATH environment for npm to find correct node.exe
- **Files**: 
  - `openclaw_installer/installer.py:265` (system Node.js)
  - `openclaw_installer/installer.py:288-294` (downloaded Node.js)
  - `openclaw_installer/installer.py:340-347` (download fallback)
  - `openclaw_installer/installer.py:459-496` (path detection)

#### 4. **Unicode Encoding Issues** ✅
- **Problem**: Windows console doesn't support Unicode characters
- **Solution**: Replaced all Unicode symbols (✓, ✗, ⚠, etc.) with ASCII ([OK], [FAIL], [SKIP])
- **Files**: `openclaw_installer/installer.py` (all console.print calls)

#### 5. **Missing Uninstall Method** ✅
- **Problem**: `uninstall()` method not implemented
- **Solution**: Added complete uninstall functionality with cleanup
- **Files**: 
  - `openclaw_installer/installer.py:433-498`
  - `openclaw_installer/cli.py:50-54`

#### 6. **Import Error** ✅
- **Problem**: `ImportError: cannot import name 'Installer'`
- **Solution**: Fixed import to use `OpenClawInstaller as Installer`
- **File**: `openclaw_installer/cli.py:10`
