TL;DR: the third-party path.py package conflicts with IPython's imports. Uninstall path.py, or upgrade IPython past the fragile era.

## The error
```text
ImportError: cannot import name path
```

## Fix it
1. Remove the conflicting package:
   ```
   pip uninstall -y path.py
   ```
   Expected: reports removal.
2. Verify:
   ```
   python -c "import IPython; print(IPython.__version__)"
   ```
   Expected: prints the version, no error.
3. Alternative: upgrade IPython and notebook to modern releases:
   ```
   pip install -U ipython notebook
   ```

## When this applies
Use this when installing or launching old IPython raises the bare cannot-import-name-path error.

## When it does not apply
If the error quotes the name ('path' with quotes) or names a from-module, it is a different import. If IPython is modern, this specific conflict does not occur.

## Compatibility
Old IPython (5.x era and earlier) with the path.py package installed.

## Root cause
Old IPython imported a name called path that the third-party path.py package also provides under a colliding import path. With both installed, Python resolved the wrong one and the expected name was missing.

## Edge cases
Some old projects genuinely need path.py; in that case upgrading IPython is the only fix. Modern IPython renamed its internals, so the conflict is extinct there.
