I am having trouble with basic installing packages and library calling

Question

When I execute

install.packages("dplyr")

I get

Error: invalid version specification ‘NA’ In addition: Warning message: In utils:::packageDescription(packageName, fields = "Version") : no package 'knitr' was found

Then I call the library and it obviously doesn't work either -

library(dplyr)

Error: package or namespace load failed for ‘dplyr’: .onLoad failed in loadNamespace() for 'pillar', details: call: utils::packageVersion("vctrs") error: package ‘vctrs’ not found In addition: Warning message: package ‘dplyr’ was built under R version 3.5.3

I am trying to use %>% and mutate. Will not post that full code due to company policy. I just need help with why something as simple as installing packages and calling libraries doesn't work for me...

The error explains the problem. The package knitr was not found. install.packages('knitr'). Alternatively it is likely to be fixable just executing install.packages("dplyr", dependencies = TRUE) to install all dependencies. — Oliver

Have you tried

 install.packages('knitr', dependencies = TRUE)

?

Let me know if this doesn't work.
