Um eine virtuelle Umgebung zu erstellen, können Sie das `venv`-Modul verwenden, das mit Python geliefert wird.

<div class="termy">

```console
$ python -m venv .venv

/// details | Was dieser Befehl bedeutet

* `python`: das Programm namens `python` verwenden
* `-m`: ein Modul als Skript aufrufen, wir geben als nächstes an, welches Modul

    `multipart/mixed; boundary="abc"`.

 *  New: `Authenticator.JAVA_NET_AUTHENTICATOR` forwards authentication requests to
    `java.net.Authenticator`. This obsoletes `JavaNetAuthenticator` in the `okhttp-urlconnection`
    module.

 *  New: `CertificatePinner` now offers an API for inspecting the configured pins.

 *  Upgrade: [Okio 2.6.0][okio_2_6_0].

    ```kotlin
    implementation("com.squareup.okio:okio:2.6.0")

/// tip | Подсказка

Иногда при попытке обновить pip вы можете получить ошибку **`No module named pip`**.

Если это произошло, установите и обновите pip с помощью команды ниже:

<div class="termy">

```console
$ python -m ensurepip --upgrade

---> 100%
```

</div>
