在編輯器中使用它，才能真正體會到 FastAPI 的好處，可以看到你只需編寫少量程式碼，以及所有的型別檢查、自動補齊等功能。

## 安裝 FastAPI { #install-fastapi }

第一步是安裝 FastAPI。

確保你建立一個[虛擬環境](../virtual-environments.md)，啟用它，然後**安裝 FastAPI**：

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note | 注意

## Instale o Programa Servidor { #install-the-server-program }

Quando você instala o FastAPI, ele vem com um servidor de produção, o Uvicorn, e você pode iniciá-lo com o comando `fastapi run`.

Mas você também pode instalar um servidor ASGI manualmente.

      uses: actions/checkout@v4
      with:
        repository: codelibs/fess-parent
        ref: ${{ env.PARENT_BRANCH }}
        path: fess-parent
    - name: Install fess-parent
      run: |
        cd fess-parent
        mvn install -Dgpg.skip=true
    - name: Build with Maven

 String[], Logger, Download, java.io.File, java.io.File); } org/gradle/wrapper/Install$1.class package org.gradle.wrapper; public final class Install$1 implements java.util.concurrent.Callable { public void Install$1(java.io.File, java.io.File, java.net.URI, Install, WrapperConfiguration); public final Object call(); } org/gradle/wrapper/Install$InstallCheck.class package org.gradle.wrapper; public final class Install$InstallCheck { public final java.io.File gradleHome; public final String failureMessage;...

## Install `websockets` { #install-websockets }

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and install `websockets` (a Python library that makes it easy to use the "WebSocket" protocol):

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

      uses: actions/checkout@v4
      with:
        repository: codelibs/fess-parent
        ref: ${{ env.PARENT_BRANCH }}
        path: fess-parent
    - name: Install fess-parent
      run: |
        cd fess-parent
        mvn install -Dgpg.skip=true
    - name: Download Plugins with Maven
      run: mvn -B antrun:run --file pom.xml
    - name: Build with Maven

                                <la:message key="labels.plugin_install"/>
                            </h3>
                        </div>
                        <la:form action="/admin/plugin/install" enctype="multipart/form-data">
                        <div class="card-body">
                            <ul class="nav nav-tabs" role="tablist">

 * https://lauri.võsandi.com/2017/03/yubikey-for-ssh-auth.html
 *
 * Using PKCS11 support in the JDK.
 * https://tersesystems.com/blog/2018/09/08/keymanagers-and-keystores/
 *
 * Install OpenSC separately. On a mac `brew cast install opensc`.

@SuppressSignatureCheck
class YubikeyClientAuth {
  fun run() {
    // The typical PKCS11 slot, may vary with different hardware.
    val slot = 0

## Встановіть серверну програму { #install-the-server-program }

Після встановлення FastAPI ви отримуєте продакшн-сервер Uvicorn і можете запускати його командою `fastapi run`.

Але ви також можете встановити ASGI-сервер вручну.

---

## FastAPIをインストールする { #install-fastapi }

最初のステップは、FastAPIのインストールです。

[仮想環境](../virtual-environments.md) を作成して有効化し、それから **FastAPIをインストール** してください:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>
