摘抄解决方法如下：

File and Folder Permissions

• Now that we got all of that out of the way, let’s talk about permissions in Windows. Every file and every folder in Windows has its own set of permissions. Permissions can be broken down into Access Control Lists with users and their corresponding rights. Here is an example with the user list at the top and the rights at the bottom:
• Permissions are also either inherited or not. Normally in Windows, every file or folder gets their permissions from the parent folder. This hierarchy keeps going all the way up to the root of the hard drive. The simplest permissions have at least three users: SYSTEM, currently logged in user account and the Administrators group.
• These permissions usually come from the C:\Users\Username folder on your hard drive. You can access these permissions by right-clicking on a file or folder, choosing Properties and then clicking on the Security tab. To edit permissions for a particular user, click on that user and then click the Edit button.

Warning in install.packages(...) :
'lib = "C:/Program Files/R/R-4.0.2/library"' is not writable是可能路径有中文，但也有可能是权限的问题哦~~
