The root cause of your error is that numpy 2.2.6 is being **compiled from source** on your machine, and its Meson-based build system can't find a C compiler. The error `Unknown compiler(s): [['icl'], ['cl'], ['cc'], ['gcc'], ...]` confirms no compatible C toolchain is installed. This happens because pre-built numpy wheels for Python 3.14 on Windows likely don't exist yet, so pip falls back to building from source. Two important things to note: 1. **Windows is not officially supported.** The Superset docs state: *"Superset does not have official support for Windows."* [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/docs/docs/installation/docker-compose.mdx#L24-L27). You will likely encounter further issues even if you get past this numpy hurdle. 2. **Python 3.14 is too new.** Python 3.14 is currently in pre-release, and many packages (including numpy) don't ship pre-built wheels for it yet — which is exactly why pip is trying to compile from source. Superset itself hasn't been tested against 3.14 either. You should use **Python 3.11** instead. Your best options: - **Docker (recommended):** Use Docker Desktop with the provided `docker-compose.yml`. This is the smoothest path and sidesteps all Windows/compiler issues. You can have a fully functional Superset running with a single `docker compose up` command [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/docs/docs/installation/docker-compose.mdx#L24-L27). - **WSL2 (Windows Subsystem for Linux):** Install WSL2 with Ubuntu, then follow the standard Linux pip install instructions with Python 3.11. This gives you a proper Linux environment without leaving Windows. - **Fix the native install (not recommended):** If you still want a native Windows venv, install [Microsoft Visual C++ Build Tools](https://visualstudio.microsoft.com/visual-cpp-build-tools/) (which provides `cl.exe`) **and** downgrade to Python 3.11. That said, you're likely to hit more Windows-specific issues downstream. For a quick study/evaluation environment, Docker Compose is genuinely the easiest path. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](<https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fsuperset>).* --- Share context across your team and agents.
