为什么已经下载了dplyr,但library(dplyr)却错误

[boyuancong]

install.packages('dplyr')
package ‘bindrcpp’ successfully unpacked and MD5 sums checked
package ‘glue’ successfully unpacked and MD5 sums checked
package ‘tibble’ successfully unpacked and MD5 sums checked
package ‘dplyr’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
C:\Users\shiliming\AppData\Local\Temp\RtmpkreNbh\downloaded_packages
> library(dplyr)
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
不存在叫‘DBI’这个名字的程辑包
In addition: Warning message:
程辑包‘dplyr’是用R版本3.2.5 来建造的
Error: ‘dplyr’程辑包或名字空间载入失败，

不存在什么包，就额外安装这些包。
