Make sure you create a [virtual environment](../../virtual-environments.md){.internal-link target=_blank}, activate it, and then install `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info

If you are planning to use digital signature algorithms like RSA or ECDSA, you should install the cryptography library dependency `pyjwt[crypto]`.

N(e,t,o){if(Array.prototype.findIndex)return e.findIndex(function(e){return e[t]===o});var n=D(e,function(e){return e[t]===o});return e.indexOf(n)}function P(t,o,n){var i=void 0===n?t:t.slice(0,N(t,'name',n));return i.forEach(function(t){t['function']&&console.warn('`modifier.function` is deprecated, use `modifier.fn`!');var n=t['function']||t.fn;t.enabled&&e(n)&&(o.offsets.popper=g(o.offsets.popper),o.offsets.reference=g(o.offsets.reference),o=n(o,t))}),o}function k(){if(!this.state.isDestroyed){var e...

它也被設計成可作為未來的參考，讓你隨時回來查看所需的內容。

## 運行程式碼

所有程式碼區塊都可以直接複製和使用（它們實際上是經過測試的 Python 檔案）。

要運行任何範例，請將程式碼複製到 `main.py` 檔案，並使用以下命令啟動 `fastapi dev`：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>

	"github.com/minio/minio/internal/bucket/versioning"
	"github.com/minio/minio/internal/color"
	"github.com/minio/minio/internal/config/storageclass"
	"github.com/minio/minio/internal/logger"
	"github.com/minio/pkg/v3/console"
	"github.com/minio/pkg/v3/wildcard"
	"github.com/minio/pkg/v3/workers"
)

const (
	bgHealingUUID = "0000-0000-0000-0000"
)

// NewBgHealSequence creates a background healing sequence

# First Steps

The simplest FastAPI file could look like this:

{* ../../docs_src/first_steps/tutorial001.py *}

Copy that to a file `main.py`.

Run the live server:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>

In this example, the program is asking for Go 1.21 semantics and
then asking for the old pre-Go 1.21 `panic(nil)` behavior and the
new Go 1.23 `asynctimerchan=0` behavior.

Only the work module's `go.mod` is consulted for `godebug` directives.
Any directives in required dependency modules are ignored.
It is an error to list a `godebug` with an unrecognized setting.
(Toolchains older than Go 1.23 reject all `godebug` lines, since they do not
