# ModuleNotFoundError: No module named 'gnupg'

TL;DR: the maintained distribution is called python-gnupg, not gnupg. Run `pip install python-gnupg` and the import works.

```text
ModuleNotFoundError: No module named 'gnupg'
```

## The fix

```
pip uninstall -y gnupg
pip install python-gnupg
```

Verify:
```
python -c "import gnupg; print('ok')"
```
Expected output: ok.

Note: python-gnupg wraps the `gpg` binary, so you also need GnuPG installed on the system (apt install gnupg, brew install gnupg). Without the binary you get a different error at runtime, not this import error.

## When this applies
- `import gnupg` fails on a fresh virtualenv or container.
- You ran `pip install gnupg` and got the wrong, outdated package.
- Automating encryption or signing with GPG from Python.

## When it does NOT apply
- Errors about the gpg binary missing at runtime, which is a system-package problem.
- `No module named 'gnupg'` after installing python-gnupg; then check the active environment.

## Why this happens
The same distribution-name versus import-name trap as python-jose and pyOpenSSL, with an extra twist: the obvious `gnupg` name is taken by an older project. pip installs exactly what you name, so the ModuleNotFoundError persists until you use the real distribution name.

## Compatibility
python-gnupg 0.5+. Needs a system GnuPG binary (1.4 or 2.x) for actual crypto operations.
