| Symptom | Check |
|---|---|
| `python: command not found` | Try `python3 --version` on macOS/Linux or `py --version` on Windows. Then replace `python` in docs commands with the command that worked. |
| `curl: command not found` | The macOS/Linux one-command installer could not download the script. Install curl, or use manual install: `python -m pip install nanobot-ai`, replacing `python` with `python3` if needed. |
| `irm` is not recognized | PowerShell could not run the download helper. Use manual install: `python -m pip install nanobot-ai`, or `py -m pip install nanobot-ai` on Windows. |
| `curl: command not found` | The macOS/Linux one-command installer could not download the script. Install curl, or use a manual isolated install such as `uv tool install nanobot-ai` or `pipx install nanobot-ai`. |
| `irm` is not recognized | PowerShell could not run the download helper. Use manual install: `uv tool install nanobot-ai`, `pipx install nanobot-ai`, or `py -m pip install nanobot-ai` inside an environment you control. |
| Could not download `raw.githubusercontent.com` | Your network, proxy, or firewall blocked the installer script download. Use manual install from PyPI, or configure your proxy and rerun the command. |
| `nanobot: command not found` | Use the module form, for example `python -m nanobot ...`, `python3 -m nanobot ...`, or `py -m nanobot ...`. Reinstall with the same Python command, or add that Python's scripts directory to `PATH`. |
| `No module named nanobot` | You are running a different Python than the one used for installation. Run `python -m pip show nanobot-ai`, `python3 -m pip show nanobot-ai`, or `py -m pip show nanobot-ai`, matching the command that installed nanobot. |
| `pip is not available` | The installer tries `python -m ensurepip --upgrade` first. If that fails, install pip for that Python, or use a Python installer/distribution that includes pip. |
| `externally-managed-environment` | Your system Python blocks global pip installs. The one-command installer retries with `--user`; if that still fails, create a virtual environment or install with `uv`/`pipx`. |
| `pip is not available` | When the installer uses a virtual environment, it tries `python -m ensurepip --upgrade`. If that fails, install pip for that Python, or use a Python installer/distribution that includes pip. |
| `externally-managed-environment` | Your system Python blocks global pip installs. Use the one-command installer, `uv tool install nanobot-ai`, `pipx install nanobot-ai`, or create a virtual environment; do not add `--break-system-packages` for nanobot. |
| Installer chose the wrong Python | Set `PYTHON` before running the installer, such as `PYTHON=python3 sh -c "$(curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh)"` or `$env:PYTHON="py"` before the PowerShell command. |
| Editable source install does not update | From the repo root, run `python -m pip install -e .` again with the Python command used for development, then check `python -m nanobot --version` or `nanobot --version`. |
| WebUI build tools missing | They are only needed for WebUI development. Packaged installs already include the WebUI bundle. |
