Fix it with Stella · Dev environment
“externally-managed-environment”? Just run the script.
pip refusing to install, conda and pip fighting, “No module named…” right after a successful install. Stella sets up the right virtual environment, installs what your script actually needs, and runs it — no --break-system-packages roulette.
Free. No credit card, no trial. Go is $5/mo, Pro is $15/mo.

Try this prompt
“pip says 'this environment is externally managed' and my script won't run. Set it up properly and run it.”
You: pip says 'this environment is externally managed' and my script won't run. Set it up properly and run it. Stella: That's your system Python protecting itself. I'll make a venv, install what the script needs, and run it there. You: No --break-system-packages. Stella: Didn't. venv is active, deps installed, script finished clean.
On this problem
What Stella actually does.
- Reads the error and your script to see what's actually needed
- Creates a proper virtual environment (venv, uv, or pipx — whatever fits)
- Installs the requirements into it, untangling any pip/conda conflicts
- Fixes PATH / wrong-python issues and runs the script to confirm it works
