你可以使用 Python 的 `venv` 模块在一个目录中创建虚拟环境：

<div class="termy">

```console
$ python -m venv env
```

</div>

这将使用 Python 程序创建一个 `./env/` 目录，然后你将能够为这个隔离的环境安装软件包。

### 激活虚拟环境

使用以下方法激活新环境：

//// tab | Linux, macOS

<div class="termy">

```console
$ source ./env/bin/activate
```

</div>

////

//// tab | Windows PowerShell

<div class="termy">

```console

import org.codelibs.fess.util.ComponentUtil;
import org.codelibs.fess.util.InputStreamThread;

import jakarta.annotation.PostConstruct;

public class CommandGenerator extends BaseThumbnailGenerator {
    private static final Logger logger = LogManager.getLogger(CommandGenerator.class);

    protected List<String> commandList;

    protected long commandTimeout = 30 * 1000L;// 30sec
