the tidyverse package is installed on my R studio (R version 3.6.1 (2019-07-05) using Mac Catalina. but I can not run the tidyverse library. and always says "Error: package or namespace load failed for ‘tidyverse’:
object ‘is_present’ is not exported by 'namespace:lifecycle"
I have tried to find the solution in internet, and I can see that there was similar problem raised in this community (cannot load tidyverse) but do not see if it was solved.
Anyone who has solution is much appreciated.
Thanks in advance.
