that would mean that you would use exactly the version `0.45.0`.

Or you could also pin it with:

```txt
fastapi>=0.45.0,<0.46.0
```

that would mean that you would use the versions `0.45.0` or above, but less than `0.46.0`, for example, a version `0.45.2` would still be accepted.

If you use any other tool to manage your installations, like Poetry, Pipenv, or others, they all have a way that you can use to define specific versions for your packages.

	// move them over the originals
	fProjects, err := os.OpenFile(projectsFile, os.O_RDONLY|os.O_CREATE, 0644)
	if err != nil {
		err = fmt.Errorf("unable to open %s: %v", projectsFile, err)
		return nil, nil, err
	}
	fProjid, err := os.OpenFile(projidFile, os.O_RDONLY|os.O_CREATE, 0644)
	if err == nil {
		// Check once more, to ensure nothing got changed out from under us
		if err = projFilesAreOK(); err == nil {

	}
	if err := certOut.Close(); err != nil {
		log.Fatalf("Error closing cert.pem: %v", err)
	}
	log.Print("wrote cert.pem\n")

	keyOut, err := os.OpenFile("key.pem", os.O_WRONLY|os.O_CREATE|os.O_TRUNC, 0600)
	if err != nil {
		log.Fatalf("Failed to open key.pem for writing: %v", err)
	}
	privBytes, err := x509.MarshalPKCS8PrivateKey(priv)
	if err != nil {
		log.Fatalf("Unable to marshal private key: %v", err)
	}

例如，假设你在应用程序中使用版本`0.45.0`。

如果你使用`requirements.txt`文件，你可以使用以下命令指定版本：

````txt
fastapi==0.45.0
````

这意味着你将使用版本`0.45.0`。

或者你也可以将其固定为：

````txt
fastapi>=0.45.0,<0.46.0
````

这意味着你将使用`0.45.0`或更高版本，但低于`0.46.0`，例如，版本`0.45.2`仍会被接受。

如果你使用任何其他工具来管理你的安装，例如 Poetry、Pipenv 或其他工具，它们都有一种定义包的特定版本的方法。

## 可用版本

你可以在[发行说明](../release-notes.md){.internal-link target=_blank}中查看可用版本（例如查看当前最新版本）。

## 关于版本

func TestBackupFile(t *testing.T) {
	dir, err := os.MkdirTemp("", "gofmt_test")
	if err != nil {
		t.Fatal(err)
	}
	defer os.RemoveAll(dir)
	name, err := backupFile(filepath.Join(dir, "foo.go"), []byte("  package main"), 0644)
	if err != nil {
		t.Fatal(err)
	}
	t.Logf("Created: %s", name)

También puedes fijar las versiones de esta forma:

```txt
fastapi>=0.45.0,<0.46.0
```

esto significa que usarás la versión `0.45.0` o superiores, pero menores a la versión `0.46.0`, por ejemplo, la versión `0.45.2` sería aceptada.
