Failed to install package "devtools"

when i try to install package devtool, there is warning

Warning in install.packages :
error 1 in extracting from zip file
Warning in install.packages :
cannot open compressed file 'BH/DESCRIPTION', probable reason 'No such file or directory'
Error in install.packages : cannot open the connection

What is that mean and how can i fix this?

Can you post the command you are using and the whole output?
