/// tip | 提示

你可以在 [环境变量](environment-variables.md#path-environment-variable) 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`

Go 1.22 changed how the runtime interacts with transparent huge pages on Linux.
In particular, a common default Linux kernel configuration can result in
significant memory overheads, and Go 1.22 no longer works around this default.
To work around this issue without adjusting kernel settings, transparent huge
