R package installation error: no package called ‘org.Hs.eg.db’

Question

I am trying to install this package http://bioconductor.org/packages/release/data/annotation/html/org.Hs.eg.db.html . When I try to load org.Hs.eg.db using library (org.Hs.eg.db) , gives me this

error: Error in library(org.Hs.eg.db) : 
  there is no package called ‘org.Hs.eg.db’ 

It says the packages are downloaded here:

The downloaded source packages are in
    ‘/tmp/Rtmpgy1ZJE/downloaded_packages’

What could be the reason for this?

如果您今天遇到此错误，则必须使用

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