Hypercorn を使う場合も、同様に `--root-path` オプションがあります。

/// note | 技術詳細

このユースケース向けに、ASGI 仕様は `root_path` を定義しています。

そして `--root-path` コマンドラインオプションは、その `root_path` を提供します。

///

### 現在の `root_path` の確認 { #checking-the-current-root-path }

各リクエストでアプリケーションが使用している現在の `root_path` は取得できます。これは（ASGI 仕様の一部である）`scope` 辞書に含まれます。

ここではデモのため、メッセージに含めています。

Ativar um ambiente virtual também muda algumas outras coisas, mas esta é uma das mais importantes.

## Verificando um ambiente virtual { #checking-a-virtual-environment }

Ao verificar se um ambiente virtual está ativo, por exemplo com:

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

<div class="termy">

```console
$ which python

// The value returned is the logical OR of multiple possible formats.
// If the value is FormatUnknown, then the input Header cannot be encoded
// and an error is returned explaining why.
//
// As a by-product of checking the fields, this function returns paxHdrs, which
// contain all fields that could not be directly encoded.
// A value receiver ensures that this method does not mutate the source Header.

    @Keep
    public void checkArray(Converter<String, Integer> c, String s) {
      calledWith(c, s);
    }

    void check() {
      runTester();
      @SuppressWarnings("unchecked") // We are checking it anyway
      Converter<String, Integer> defaultConverter =
          (Converter<String, Integer>) getDefaultParameterValue(0);
      assertEquals(Integer.valueOf(0), defaultConverter.convert("anything"));

            candidateSource = new FileModelSource(candidateModel.getPomFile());
        }

一個重要的細節是，虛擬環境路徑會被放在 `PATH` 變數的**開頭**。系統會在找到任何其他可用的 Python **之前**找到它。這樣，當你運行 `python` 時，它會使用**虛擬環境中的** Python，而不是任何其他 `python`（例如，全域環境中的 `python`）。

啟用虛擬環境還會改變其他一些內容，但這是它所做的最重要的事情之一。

## 檢查虛擬環境 { #checking-a-virtual-environment }

當你檢查虛擬環境是否啟動時，例如：

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

<div class="termy">

```console
$ which python

/home/user/code/awesome-project/.venv/bin/python
```

并使用这个。

一个重要的细节是，虚拟环境路径会被放在 `PATH` 变量的**开头**。系统会在找到任何其他可用的 Python **之前**找到它。这样，当你运行 `python` 时，它会使用**虚拟环境中**的 Python，而不是任何其他 `python`（例如，全局环境中的 `python`）。

激活虚拟环境还会改变其他一些东西，但这是它所做的最重要的事情之一。
