Package Manager 窗口

Use the Unity Package Manager (in Unity’s top menu: Window > Package Manager) to view which packages and feature sets are available for installation or already installed in your project. You can also use this window to see which package versions are available, and install, remove, disable, or update packages and feature sets for each project.

Package Manager 窗口显示以下内容：

(A) The experimental package indicator, which warns you if your project contains experimental packages.

(B) The add button, which you can click to install a package directly into your project by entering a git URL, a local path, or a package name.

(C) The Packages menu, which you can use to change what appears in the list (context).

(D) The Sort menu, which you can use to sort the list of packages and feature sets by name or date.

(E) The Filters menu and the Clear Filters button display on all lists except the Built-in list. Filtering allows you to narrow down which packages appear in the list.

(F) The Advanced menu , which you can use to access the project settings for the Package Manager and more. See Advanced settings for details.

(G) The search box, which you can use to look for packages and feature sets by name.

(H) The list view, which displays packages that match the filter and search parameters you specify. The All tab lists all packages that meet your filter and search criteria, while the Services tab filters the list further to display services.

(I) The detail view, which displays information specific to the feature set or package selected in the list.

(J) The package details tabs, which display further information about the selected feature set or package. The tabs are dynamic, based on the selected item. For information about these tabs, see Details view.

(K) Buttons to perform any of the following actions at the project level:

Install or remove feature sets
Install, update, or remove packages
Download and import, or update Asset Store packages
Disable or enable built-in packages

(L) The status bar, which displays information when the Package Manager loads packages and feature sets. This information includes errors and warning messages, the number of Asset Store packages available, and a link to load more Asset Store packages.

(M) The Refresh list lets you refresh the list of packages displayed. In the My Assets context, Refresh list is a menu, which contains a Check for updates option, so you can check for updates to all packages on your computer; not just the ones that are visible in the My Assets context.
