You normally have to do this only **once**, when you create the virtual environment.

/// tip | 提示

通常你只需要在创建虚拟环境时执行此操作**一次**。

///

## 退出虚拟环境 { #deactivate-the-virtual-environment }

当你完成工作后，你可以**退出**虚拟环境。

<div class="termy">

```console
$ deactivate
```

</div>

<div class="termy">

```console
$ cd ~/code/prisoner-of-azkaban

// You don't need to be in the old directory to deactivate, you can do it wherever you are, even after going to the other project 😎
$ deactivate

// Activate the virtual environment in prisoner-of-azkaban/.venv 🚀
$ source .venv/bin/activate

// Now when you run python, it will find the package sirius installed in this virtual environment ✨
$ python main.py

    public List<String> getInactiveProfileIds() {
        return inactiveProfileIds;
    }

    /**
     * Sets the identifiers of those profiles that should be deactivated by explicit demand.
     *
     * @param inactiveProfileIds The identifiers of those profiles to deactivate, may be {@code null}.
     * @return This context, never {@code null}.

installed we may want to check the license and make users agree. We may also want to unpack the given plugin in a particular location.

We might want to separate between installation and activation, it might be nice to allow a user to activate/deactivate a plugin instead of having to uninstall and reinstall a plugin in particular cases. This would prevent having to reconfigure the plugin again. For example it might be nice to turn off LDAP authentication without having to uninstall the plugin....
