//// tab | Linux, macOS

<div class="termy">

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

//// tab | Windows PowerShell

<div class="termy">

```console

Проверьте, что всё сработало:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
$ which pip

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

</div>

////

//// tab | Windows PowerShell

<div class="termy">

```console
$ Get-Command pip

<div class="termy">

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

</div>

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:

//// tab | Linux, macOS

<div class="termy">

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

<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：

//// tab | Linux, macOS

<div class="termy">

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

</div>

////

//// tab | Windows PowerShell

<div class="termy">

```console

Do this **every time** you start a **new terminal session** to work on the project.

👆 💪 ✍ 🕹 🌐 📁 ⚙️ 🐍 `venv` 🕹:

<div class="termy">

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

</div>

👈 🔜 ✍ 📁 `./env/` ⏮️ 🐍 💱 &amp; ⤴️ 👆 🔜 💪 ❎ 📦 👈 ❎ 🌐.

### 🔓 🌐

🔓 🆕 🌐 ⏮️:

//// tab | 💾, 🇸🇻

<div class="termy">

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

</div>

////

//// tab | 🚪 📋

<div class="termy">

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

<div class="termy">

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

</div>

Cela va créer un répertoire `./env/` avec les binaires Python et vous pourrez alors installer des paquets pour cet environnement isolé.

### Activer l'environnement

Activez le nouvel environnement avec :

//// tab | Linux, macOS

<div class="termy">

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

<div class="termy">

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

</div>

Isso criará o diretório `./env/` com os binários Python e então você será capaz de instalar pacotes nesse ambiente isolado.

### Ativar o ambiente

Ative o novo ambiente com:

//// tab | Linux, macOS

<div class="termy">

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

</div>

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// Sie könnten eine Umgebungsvariable MY_NAME erstellen mittels
$ export MY_NAME="Wade Wilson"

// Dann könnten Sie diese mit anderen Programmen verwenden, etwa
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>

////

//// tab | Windows PowerShell

<div class="termy">

```console

There is a script that you can run that will format and clean all your code:

<div class="termy">

```console
$ bash scripts/format.sh
```

</div>

It will also auto-sort all your imports.

## Tests

There is a script that you can run locally to test all the code and generate coverage reports in HTML:

<div class="termy">

```console
$ bash scripts/test-cov-html.sh
```

</div>
