[Docs] Add installation troubleshooting for npm v7+ and build steps by PratapShashwat · Pull Request #836 · MetaCell/NetPyNE-UI
I encountered 404/500 errors during installation due to missing build steps and dependency conflicts.
This PR adds a 'Troubleshooting' section to README.md to help new contributors.
Includes specific fixes for:
- Dependency Conflicts: Added instructions for `npm install --legacy-peer-deps` (required for npm v7+).
- Missing Frontend Assets: Added step to run `npm run build` inside the webapp folder (fixes 500/FileNotFound errors).
- Jupyter Connection: Added commands to manually enable server/notebook extensions (fixes 404 errors).
