When I tried to install the package org.Hs.eg.db in R (version 3.5.2), I met some problems which are listed as follows.

Do you have any suggestions?

Thank you.

Warning message:

Try to correct the first problem reported, missing 'DBI', with

BiocManager::install("DBI")

Then if successful

BiocManager::install("AnnotationDbi")

and finally

BiocManager::install("org.Hs.eg.db")
