`fastapi dev` 명령어에 파일 경로를 전달할 수도 있으며, 그러면 사용할 FastAPI 앱 객체를 추정합니다:

```console
$ fastapi dev main.py
```

하지만 매번 `fastapi` 명령어를 호출할 때 올바른 경로를 전달하는 것을 기억해야 합니다.

또한 [VS Code 확장](editor-support.md)이나 [FastAPI Cloud](https://fastapicloud.com) 같은 다른 도구에서는 이를 찾지 못할 수도 있으므로, `pyproject.toml`의 `entrypoint`를 사용하는 것을 권장합니다.

## `fastapi dev` { #fastapi-dev }

`fastapi dev`를 실행하면 개발 모드가 시작됩니다.

            // Leading zeros removed and consecutive zeros compressed
            assertEquals("2001:db8::1", method.invoke(null, "2001:0db8:0:0:0:0:0:1"));

            // Longest sequence of zeros compressed (3 zeros at end vs 1 zero at start)
            assertEquals("2001:db8:0:1::1", method.invoke(null, "2001:0db8:0:1:0:0:0:1"));

            // No compression when all segments are non-zero (just remove leading zeros)

	objectLockEnabled := false
	if vs := r.Header.Get(xhttp.AmzObjectLockEnabled); len(vs) > 0 {
		v := strings.ToLower(vs)
		switch v {
		case "true", "false":
			objectLockEnabled = v == "true"
		default:
			writeErrorResponse(ctx, w, errorCodes.ToAPIErr(ErrInvalidRequest), r.URL)
			return
		}
	}

	forceCreate := false
	if vs := r.Header.Get(xhttp.MinIOForceCreate); len(vs) > 0 {

如果你不想包含那些可選的依賴項，你可以改為安裝 `pip install fastapi`。

如果你想安裝標準依賴項，但不包含 `fastapi-cloud-cli`，可以使用 `pip install "fastapi[standard-no-fastapi-cloud-cli]"` 安裝。
