我刚刚升级到新的ggplot2软件包（2.0.0），但每次尝试加载它时都会出错。
> library(ggplot2)
Error in get(method, envir = home) :
lazy-load database 'C:/Users/<blahblahblah>/Documents/R/win-library/3.2/ggplot2/R/ggplot2.rdb' is corrupt
In addition: Warning messages:
1: package ‘ggplot2’ was built under R version 3.2.3
2: In .registerS3method(fin[i, 1], fin[i, 2], fin[i, 3], fin[i, 4], :

3: In get(method, envir = home) :

4: In get(method, envir = home) : internal error -3 in R_decompress1
Error: package or namespace load failed for ‘ggplot2’
我能在R中加载其他包，例如dplyr，这意味着我的“R_decompress1”函数没有任何问题，因为它在所有包中都需要。然后我认为CRAN上的二进制文件可能已损坏（不太可能，但很容易检查）。我使用github页面上建议的方法从当前源安装。
> devtools::install_github("hadley/ggplot2")
> library(ggplot2)
Error in get(Info[i, 1], envir = env) :

In addition: Warning message:

Error: package or namespace load failed for ‘ggplot2’
我正在使用Windows 7平台上的R版本3.2.1和RStudio 0.99.842。有什么想法吗？
编辑：
要求我提供install命令的输出：
