r3.4.2库中的错误(ggplot2):没有名为“ggplot2”的包

I'm new to R and I'm just trying to get through some tutorials.

我是R的新手，我只是想通过一些教程。

When I try installing ggplot2, I get this error.

当我尝试安装ggplot2时，我得到了这个错误。

Error in library(ggplot2) : There is no package called 'ggplot2'

I tried these in R and RStudio.

我在R和RStudio中尝试过这些。

install.packages("ggplot2", dep=T)

install.packages('ggplot2', repos='http://cran.us.r-project.org')

remove.packages("ggplot2")

but I get the error

但是我得到了误差。

(Error in remove.packages : there is no package called 'ggplot2')

This is what I get from install.packages("ggplot2")

这是我从install.package(“ggplot2”)中得到的。

> install.packages("ggplot2")

I removed all ggplot2 files manually then tried to install again. Here's my result.

我手动删除了所有的ggplot2文件，然后尝试重新安装。这是我的结果。

在讨论这个问题时，我建议:

try turning it off and on again
试着把它关掉。
update R to last version if possible
如果可能的话，更新R到最后一个版本。
remove manually all the folders related to the relevant package and retry the installation
手动删除与相关包相关的所有文件夹，并重试安装。
