从注册表中安装

注意：通过 Package Manager 窗口安装包时，Package Manager 会评估其他包及其依赖项，以查看是否存在任何与所选版本冲突的版本。如果检测到任何冲突或限制，则会安装可解决这些问题的任何版本。有关更多信息，请参阅依赖关系和解决方法。

使用相同的过程从 Unity 注册表或项目中定义的任何作用域注册表安装包。唯一的区别是从 Packages 下拉菜单中选择什么：

1. Open the Package Manager window and select Unity Registry from the Packages drop-down menu. If you set up a scoped registry and you want to install a package from a scoped registry, choose My Registries instead.

   Note: If you haven’t defined any scoped registries for this project, My Registries doesn’t appear in the drop-down menu.

   

2.从包列表中选择要安装的包。包信息将显示在详细信息视图中。

**Note:** If you don't see the package you want to install in the list of packages, it might be an undiscoverable package, such as [experimental](pack-exp.html) and [pre-release](pack-preview.html) packages. The Package Manager doesn't display experimental packages unless they are already installed, but pre-release packages appear in the Package Manager when you enable the [Enable Pre-release Packages](class-PackageManager.html#advanced_preview) project setting.

3.选择要安装的版本。有关可用版本的更多信息，请参阅查找特定版本。

4.单击 Install 按钮。

进度条结束后，即可使用新的包。

Note: You can install multiple packages with one click by using the multiple select feature. For more information, see Perform an action on multiple packages or feature sets.
