Package Manager 窗口

Access the Package Manager window from the Unity Editor’s Window menu.

Use the Package Manager window to view which packages and feature sets are available for installation or already installed in your project. You can also use this window to check 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 has experimental packages.

(B) The install 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 navigation panel, which you can use to select a context to change what appears in the list panel (H).

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

(E) The Filter menu, which you can use to narrow down which packages appear in the list panel (H). The Filters menu and the Clear Filters button are disabled for the Built-in list. They’re also disabled for the In Project context (unless you have subscription-based packages), because that context in the navigation panel has a nested item for Updates.

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

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

(H) The list panel, which displays packages for the type you selected in the navigation panel, limited by any filter and search parameters you specified.

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

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

(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, update, or remove Asset Store packages
• Disable or enable built-in packages
• Install or remove services

(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 button lets you refresh the list of packages displayed. In the My Assets context, Refresh list is a menu, which has a Check for updates option. You can use Check for updates to check for updates to all packages on your computer, not just the ones that are visible in the My Assets context.

Advanced 设置

The advanced settings menu allows you to perform these actions:

状态栏

The Package Manager displays messages in the status bar at the bottom of the Package Manager window.

There are typically four status messages that the Package Manager might display:

• The first time you open the Package Manager window in a new project, the Refreshing list message appears briefly:

  

  This message also appears when you click Refresh list

• When you select the My Assets context in the navigation panel, the load bar appears above the date. It displays the number of Asset Store packages and a Load link:

  

• Most of the time, the status bar displays the date and time of when the Package Manager window last refreshed its information. However, if the Package Manager detects a problem, such as a network issue, the Package Manager prompts you to sign in:

  

• If your network connection is working, but you aren’t signed into your Unity account, the Package Manager doesn’t display any Asset Store packages. When you select My Assets in the navigation panel, the Package Manager prompts you to sign in:

  

  In the list panel, click Sign in to sign in to your Unity account through the Unity Hub.
