If you have an older version, you would get errors when trying to use `Annotated`.

Make sure you [Upgrade the FastAPI version](../../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} to at least 0.95.1 before using `Annotated`.

### Import `Depends`

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[3] *}

### Declare the dependency, in the "dependant"

And then you can also have a path `/users/{user_id}` to get data about a specific user by some user ID.

Because *path operations* are evaluated in order, you need to make sure that the path for `/users/me` is declared before the one for `/users/{user_id}`:

```Python hl_lines="6  11"
{!../../docs_src/path_params/tutorial003.py!}
```

Activating a virtual environment adds its path `.venv/bin` (on Linux and macOS) or `.venv\Scripts` (on Windows) to the `PATH` environment variable.

Let's say that before activating the environment, the `PATH` variable looked like this:

//// tab | Linux, macOS

```plaintext
/usr/bin:/bin:/usr/sbin:/sbin
```

That means that the system would look for programs in:

     * is referenced somewhere for as long as the enum class is loaded. *Maybe in theory* the enum
     * class could be unloaded after the above call to `getEnumConstants` but before we call
     * `get()`, but that is vanishingly unlikely.
