Usá-lo em seu editor é o que realmente te mostra os benefícios do FastAPI, ver quão pouco código você tem que escrever, todas as conferências de tipo, preenchimento automático, etc.

## Instale o FastAPI { #install-fastapi }

O primeiro passo é instalar o FastAPI.

Certifique-se de criar um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ativá-lo e então **instalar o FastAPI**:

	// GlobalStaleUploadsExpiry - Expiry duration after which the uploads in multipart,
	// tmp directory are deemed stale.
	GlobalStaleUploadsExpiry = time.Hour * 24 // 24 hrs.

	// GlobalStaleUploadsCleanupInterval - Cleanup interval when the stale uploads cleanup is initiated.
	GlobalStaleUploadsCleanupInterval = time.Hour * 6 // 6 hrs.

	// Refresh interval to update in-memory iam config cache.

 *   // The resource was cached! Show it.
 * } else {
 *   // The resource was not cached.
 * }
 * ```
 *
 * This technique works even better in situations where a stale response is better than no response.
 * To permit stale cached responses, use the `max-stale` directive with the maximum staleness in
 * seconds:
 *
 * ```java
 * Request request = new Request.Builder()
 *     .cacheControl(new CacheControl.Builder()

Durante a instalação do Python, você pode ser questionado sobre a atualização da variável de ambiente `PATH`.

//// tab | Linux, macOS

Vamos supor que você instale o Python e ele fique em um diretório `/opt/custompython/bin`.

Se você concordar em atualizar a variável de ambiente `PATH`, o instalador adicionará `/opt/custompython/bin` para a variável de ambiente `PATH`.

	if cache.status == scanStateSuccess || cache.status == scanStateStarted {

			cache.error = err.Error()

	}
	sys.Unlock()
}

// RemoveStaleBuckets removes all stale buckets in memory that are not on disk.

			// initial server startup, however, it is needed for the case where
			// the STS account's policy mapping (for example in LDAP mode) may
			// be changed and the user's policy mapping in memory is stale

			// server).
			//
			// The "policy not found" error is ignored because the STS account may

## Retrying Requests

Sometimes connections fail: either a pooled connection was stale and disconnected, or the webserver itself couldn’t be reached. OkHttp will retry the request with a different route if one is available.
