=== "Windows PowerShell"

    <div class="termy">

    ```console
    $ .\env\Scripts\Activate.ps1
    ```

    </div>

=== "Windows Bash"

    Or if you use Bash for Windows (e.g. <a href="https://gitforwindows.org/" class="external-link" target="_blank">Git Bash</a>):

    <div class="termy">

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

    </div>

    <div class="termy">

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

    </div>

Проверьте, что всё сработало:

=== "Linux, macOS, Windows Bash"

    <div class="termy">

    ```console
    $ which pip

    some/directory/fastapi/env/bin/pip
    ```

    </div>

=== "Windows PowerShell"

    <div class="termy">

    ```console

Um zu überprüfen, ob es funktioniert hat, geben Sie ein:

=== "Linux, macOS, Windows Bash"

    <div class="termy">

    ```console
    $ which pip

    some/directory/fastapi/env/bin/pip
    ```

    </div>

=== "Windows PowerShell"

    <div class="termy">

    ```console
    $ Get-Command pip

    some/directory/fastapi/env/bin/pip
    ```

    </div>

你可以使用 Python 的 `venv` 模块在一个目录中创建虚拟环境：

<div class="termy">

```console
$ python -m venv env
```

</div>

这将使用 Python 程序创建一个 `./env/` 目录，然后你将能够为这个隔离的环境安装软件包。

### 激活虚拟环境

使用以下方法激活新环境：

=== "Linux, macOS"

    <div class="termy">

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

    </div>

=== "Windows PowerShell"

    <div class="termy">

    ```console

                <div class="collapse" id="accept-${changeId}">
                  <div class="well">
                      In order to accept this change add the following to <code>${relativePathToMainApiChanges()}</code>:
                    <pre>${prettyPrintJson(acceptanceJson)}</pre>
                  </div>
                </div>
                </p>
                <p>

Pythonの`venv`モジュールを使用して、ディレクトリに仮想環境を作成します:

<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

新しい環境を有効化するには:

=== "Linux, macOS"

    <div class="termy">

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

    </div>

=== "Windows PowerShell"
