无法在 R 中安装 tidyverse 包。错误没有调用包

Question

I am attempting to install the package tidy verse in R studio and receiving these errors.

> install.packages('tidyverse')
also installing the dependency ‘rstudioapi’

  There is a binary version available but the source version is later:
           binary source needs_compilation
rstudioapi  0.9.0   0.10             FALSE

  there is no package called ‘assertthat’

The downloaded source packages are in

In addition I've attempted to install in base R and receive the same message. I've gone to the temporary folders and unzipped the package and moved that over to the library folder. When I attempt library(assertthat) it gives me an error that there is not a valid package installed.

I've successfully installed tidyverse before on this machine, but when trying to use it this time it told me it was not installed, so I've attempted to reïnstall it.

Answer 1

我删除了我的 .Rhistory、.Rdata 和 .Rprofile 文件，重新启动了 R 并且能够tidyverse地安装tidyverse 。

Answer 2

I restarted my computer and installed devtools using install.packages("devtools") .

After that I made sure to put Rtools on the PATH , simply following the instructions here: Using Rtools40 on Windows

Afterwards, I was able to install tidyverse using install.packages("tidyverse") .
