Cannot install new version of htmltools 0.5.4 about htmltools HOT 3 CLOSED

Hi,

I have installed R in Mac using command "conda create -n r_env r-essentials r-base" and after that I installed a specific package that I want "dplR". When I run Jupyter notebook, I am getting following error messages in Mac terminal :
