Good afternoon. Recently I`ve faced a problem, connected with the installation of "devtools" package in RStudio 3.4.0. When I type:
The following message appears:
One or more of the packages that will be updated by this installation are currently loaded. Restarting R prior to updating these packages is strongly recommended. RStudio can restart R and then automatically continue the installation after restarting (all work and data will be preserved during the restart) Do you want to restart R prior to installing?
After I press "Yes", restart of the current RStudio session takes place, and the process of "devtools" package installation begins. But the installation process doesn't come to its end, and, finally, the message about the necessity of restarting current RStudio session, described above, appears.
Thank you for your help.
