## Install Packages

After activating the environment, you can install packages in it.

/// tip

Do this **once** when installing or upgrading the packages your project needs.

If you need to upgrade a version or add a new package you would **do this again**.

Поскольку `needy` является обязательным параметром, вам необходимо указать его в URL-адресе:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

...это будет работать:

```JSON
{
    "item_id": "foo-item",

* Implement and use well-known cryptographic tools, like Passlib and JWT tokens, etc.
* Add more granular permission controls with OAuth2 scopes where needed.
* ...etc.

Nevertheless, you might have a very specific use case where you really need to disable the API docs for some environment (e.g. for production) or depending on configurations from environment variables.

Aquí el parámetro de query `needy` es un parámetro de query requerido, del tipo `str`.

Si abres tu navegador en una URL como:

```
http://127.0.0.1:8000/items/foo-item
```

...sin añadir el parámetro `needy` requerido, verás un error como:

```JSON
{
    "detail": [
        {
            "loc": [
                "query",
                "needy"
            ],

```

Aqui o parâmetro de consulta `needy` é um valor obrigatório, do tipo `str`.

Se você abrir no seu navegador a URL:

```
http://127.0.0.1:8000/items/foo-item
```

... sem adicionar o parâmetro obrigatório `needy`, você verá um erro como:

```JSON
{
    "detail": [
        {
            "loc": [
                "query",
                "needy"
            ],
