# 扩展更新

Click the Check for Updates button in the Extensions dialog to check for online updates for all installed extensions. To check for online updates for only the selected extension, right-click to open the context menu, then choose Update.

要访问此命令...

Choose Tools - Extensions, click Check for Updates button.

当您点击「检查更新」按钮或选择「更新」命令时，将显示「扩展更新」对话框，并立即开始检查是否有可用更新。

检查更新时您将看到一个进度指示器。请等待对话框中显示的某些信息，或点击「取消」中止更新检查。

如果没有可用更新，对话框中的消息将通知您没有任何更新。关闭对话框。

如果有可用更新，则可以自动安装这些更新，或者必须通过某些操作进行响应:

「扩展更新」对话框可能包含不可选的条目，因此无法执行自动更新。

- 未满足依赖性 (此更新需要安装更多或更新的文件)。

- Insufficient user rights (the Extensions dialog was started from the menu, but shared extensions can only be modified when LibreOffice does not run, and only by a user with appropriate rights). See Extensions dialog for details.

- 需要进行手动更新。

当您点击「安装」按钮时，将显示「下载和安装」对话框。

现在将下载所有可直接下载的扩展。「下载和安装」对话框将显示进度。如果无法下载某个扩展，将显示一条消息。此操作将继续进行，以下载其余扩展。

Some extensions may be marked with the phrase “browser-based update”. These extensions cannot be downloaded by the Extensions dialog. A web browser must be opened to download the extension update from a particular web site. That site may require several more user interaction to download the extension. After downloading you must install the extension manually, for example by double-clicking the extension's icon in a file browser.

For extensions marked as “browser-based update”, the Extensions dialog will open your web browser on the respective web site. This happens when you close the dialog, after downloading any other extension updates. If there are no extensions which can be directly downloaded then the web browser is started immediately.

下载完最后一个扩展之后，将开始安装操作。首先删除可以成功下载更新的所有已安装的扩展。然后安装更新的扩展。如果发生错误，将显示安装失败的消息，但操作将继续进行。

如果已处理完所有更新，「下载和安装」对话框将显示操作已完成。可以通过点击「终止更新」按钮来终止下载和安装过程。

## 显示所有更新

默认情况下，只有可下载的扩展才会显示在对话框中。选中「显示所有更新」还可以显示其他扩展和错误消息。
