Error in installation and loading of the “scales” packages in R studio server version 1.0.153

Question

I am using R Studio Server version 1.0.153. I just got the "scales" package installed version 0.5.0 . But when loading the package library(scales), I get the following error:

Error in [[3L]](cond):
Package 'scales' version 0.4.1 cannot be unloaded:
Error in unloadNamespace(package) : namespace 'scales' is imported by 
'ggplot2' so cannot be unloaded.

Please help me with a possible solution.Thanks a lot.

还要在R studio中安装ggp​​lot2库。使用它之前，请不要忘记在控制台中导入库。
