这个命令会创建或修改一些[环境变量](environment-variables.md){.internal-link target=_blank}，这些环境变量将在接下来的命令中可用。

其中之一是 `PATH` 变量。

/// tip

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：
