Das erstellt ein Verzeichnis `./env/` mit den Python-Binärdateien und Sie können dann Packages in dieser lokalen Umgebung installieren.

### Umgebung aktivieren

Aktivieren Sie die neue Umgebung mit:

=== "Linux, macOS"

    <div class="termy">

    ```console
    $ source ./env/bin/activate
    ```

    </div>

=== "Windows PowerShell"

    <div class="termy">

    ```console

    ],

<div class="termy">

```console
$ python -m venv env

</div>

これにより、Pythonバイナリを含む`./env/`ディレクトリが作成され、その隔離された環境にパッケージのインストールが可能になります。

### 仮想環境の有効化
