E você normalmente instalaria essas dependências de pacote com `pip`, por exemplo:

<div class="termy">

```console
$ pip install -r requirements.txt
---> 100%
Successfully installed fastapi pydantic uvicorn
```

</div>

!!! info
    Há outros formatos e ferramentas para definir e instalar dependências de pacote.

    Eu vou mostrar um exemplo depois usando Poetry em uma seção abaixo. 👇

	cniConfigFilepath  string
}

// NewInstaller returns an instance of Installer with the given config
func NewInstaller(cfg *config.InstallConfig, isReady *atomic.Value) *Installer {
	return &Installer{
		cfg:                cfg,
		kubeconfigFilepath: filepath.Join(cfg.MountedCNINetDir, cfg.KubeconfigFilename),
		isReady:            isReady,
	}
}

func (in *Installer) installAll(ctx context.Context) (sets.String, error) {

}

// InstallCmdWithArgs generates an Istio install manifest and applies it to a cluster
func InstallCmdWithArgs(ctx cli.Context, rootArgs *RootArgs, iArgs *InstallArgs) *cobra.Command {
	ic := &cobra.Command{
		Use:     "install",
		Short:   "Applies an Istio manifest, installing or reconfiguring Istio on a cluster.",
		Long:    "The install command generates an Istio install manifest and applies it to a cluster.",

}

// create an install server instance and run it, blocking until it gets terminated
// via context cancellation
func startInstallServer(ctx context.Context, serverConfig *config.Config, t *testing.T) {
	readyFlag := &atomic.Value{}
	installer := install.NewInstaller(&serverConfig.InstallConfig, readyFlag)

	t.Logf("CNI installer created, watching...")

				CNIBinTargetDirs: []string{cniBinDir},
			}

			isReady := &atomic.Value{}
			isReady.Store(false)
			installer := NewInstaller(cfg, isReady)
			installer.cniConfigFilepath = cniConfigFilePath
			installer.kubeconfigFilepath = kubeConfigFilePath
			err := installer.Cleanup()
			if (c.expectedFailure && err == nil) || (!c.expectedFailure && err != nil) {

Install the controller manifest:

```bash
istioctl operator init --hub docker.io/<your-account> --tag latest
kubectl create ns istio-system
kubectl apply -f operator/samples/default-install.yaml
```

This installs the controller into the cluster in the istio-operator namespace. The controller in turns installs

Après avoir activé l'environnement comme décrit ci-dessus, installez `flit` :

<div class="termy">

```console
$ pip install flit

---> 100%
```

</div>

Réactivez maintenant l'environnement pour vous assurer que vous utilisez le "flit" que vous venez d'installer (et non un environnement global).

Et maintenant, utilisez `flit` pour installer les dépendances de développement :

=== "Linux, macOS"

    choco install jdk8; \
    choco install KB2533623; \
    choco install KB2919355; \
    choco install KB2919442; \
    choco install KB2999226; \
    choco install KB3033929; \
    choco install KB3035131; \
    choco install maven; \
    choco install ninja; \
    choco install nodejs --version 9.3.0; \
    choco install nodejs.install --version 9.3.0; \

			log.Info("Ambient node agent started, starting installer...")

		} else {
			// Ambient not enabled, so this readiness flag is no-op'd
			watchServerReady.Store(true)
		}

		installer := install.NewInstaller(&cfg.InstallConfig, installDaemonReady)

		repair.StartRepair(ctx, cfg.RepairConfig)

		log.Info("Installer created, watching node CNI dir")

Se você instalou Typer CLI, você pode instalar _completion_ com:

<div class="termy">

```console
$ typer --install-completion

zsh completion installed in /home/user/.bashrc.
Completion will take effect once you restart the terminal.
```

</div>
