# AttributeError: module 'jwt' has no attribute 'encode'

TL;DR: you installed the wrong `jwt` package. The dead `jwt` distribution on PyPI shadows the real one. Run `pip uninstall -y jwt PyJWT` then `pip install PyJWT`, and `jwt.encode` appears. Also check you do not have a local file named jwt.py shadowing the package.

```text
AttributeError: module 'jwt' has no attribute 'encode'
```

## The fix

1. See which distribution you actually have:
```
pip show jwt
pip show PyJWT
python -c "import jwt; print(jwt.__file__)"
```
If `pip show jwt` finds a package, that is the wrong one.

2. Remove both and install the right one:
```
pip uninstall -y jwt PyJWT
pip install PyJWT
```

3. Rule out shadowing:
```
ls jwt.py
```
If a jwt.py exists in your working directory, rename it and delete __pycache__.

4. Verify:
```
python -c "import jwt; print(jwt.encode({'a': 1}, 'secret', algorithm='HS256'))"
```
Expected output: a three-part token string.

## When this applies
- `import jwt` works but `jwt.encode` does not exist.
- `pip show jwt` reports an installed distribution.
- `jwt.__file__` points at a tiny package without encode/decode.

## When it does NOT apply
- The error is `No module named 'jwt'`, which means nothing is installed.
- You get the error only from one directory, which points at a shadowing jwt.py instead.

## Why this happens
Both distributions chose the top-level name `jwt`, so pip happily installs the wrong one and Python happily imports it. The abandoned `jwt` package has no encode function, hence the confusing AttributeError instead of an ImportError. Always `pip install PyJWT`, never `pip install jwt`.

## Compatibility
PyJWT 2.x. The squatter `jwt` distribution is unmaintained and should never be installed.
