# This file specifies the Linux OS versions on which we can't build and

# VERSION_ID from /etc/os-release, and a matching value will cause the
# Docker tests to be skipped on that OS. If /etc/os-release doesn't exist
# (as is the case on centos-6, for example) then that OS will again be

你可以在 [環境變數](environment-variables.md#path-environment-variable){.internal-link target=_blank} 部分了解更多關於 `PATH` 環境變數的內容。

///

啟用虛擬環境會將其路徑 `.venv/bin`（在 Linux 和 macOS 上）或 `.venv\Scripts`（在 Windows 上）加入到 `PATH` 環境變數中。

假設在啟用環境之前，`PATH` 變數看起來像這樣：

//// tab | Linux, macOS

```plaintext
/usr/bin:/bin:/usr/sbin:/sbin
```

這意味著系統會在以下目錄中查找程式：

* `/usr/bin`
* `/bin`
* `/usr/sbin`
* `/sbin`

你可以在 [环境变量](environment-variables.md#path-environment-variable){.internal-link target=_blank} 部分了解更多关于 `PATH` 环境变量的内容。

///

激活虚拟环境会将其路径 `.venv/bin`（在 Linux 和 macOS 上）或 `.venv\Scripts`（在 Windows 上）添加到 `PATH` 环境变量中。

假设在激活环境之前，`PATH` 变量看起来像这样：

//// tab | Linux, macOS

```plaintext
/usr/bin:/bin:/usr/sbin:/sbin
```

这意味着系统会在以下目录中查找程序：

* `/usr/bin`
* `/bin`
* `/usr/sbin`
* `/sbin`
