:PluginUpdate in Vim as usual for keeping all of the plugins
up-to-date, and the system prompted me to supply my user name and
password for GitHub.2 Initially, I refused to do so. Then
Vundle skipped the first plugin and proceeded to another one. I was
prompted again for the user name, and my response was still the same.
This repeated for several times, and finally nothing was updated.
I quitted Vim and re-opened it again, and issued the same editor command for updating the plugins, and ran into the same trouble.
Since I didn’t have much time, I finally input correctly the required account information in order to get the plugins updated. Luckily, this was needed for once only, instead of once for each plugin.
