ggplot2加载R但不加载RStudio

Question

ggplot2将加载到R而不是RStudio中的新安装的R 3.4.1和RStudio 1.0.153在Windows 10 Pro（1703）64位上。 ggplot2是版本2.2.1

在我尝试时在RStudio中：

library("ggplot2", lib.loc="C:/Program Files/R/R-3.4.1/library")

我收到错误：

Error: package or namespace load failed for ‘ggplot2’:

.onLoad failed in loadNamespace() for 'grid', details:

call: fun(libname, pkgname)

 error: object 'L_initGrid' not found
In addition: Warning messages:

1: failed to assign RegisteredNativeSymbol for layoutRegion to layoutRegion since layoutRegion is already defined in the ‘grid’ namespace 

2: failed to assign RegisteredNativeSymbol for xsplinePoints to xsplinePoints since xsplinePoints is already defined in the ‘grid’ namespace 

P.S。我用：

安装了ggplot2

install.packages('ggplot2', dep = TRUE)

ggplot2在R

中加载得很好
