Why I can't run datasets from RDatasets packages on my local machine?

I am expereincing this error when running RDatasets package:

" cannot assign a value to variable Base.sleep from module Main

[1] top-level scope
@ In[3]:2
[2] eval
@ .\boot.jl:373 [inlined]
[3] include_string(mapexpr::typeof(REPL.softscope), mod::Module, code::String, filename::String)
@ Base .\loading.jl:1196

Anyone could hint as to the possible missing action I am not taking ? Thank you.

The error seems unrelated to RDatasets.jl. You are probably trying to assign a value to the sleep variable name? The function Base.sleep is already defined in Julia and you can’t reassign the name to a variable. Please double check.
