Сбой установки Vundle?

Я пытаюсь установить Vundle, следующий инструкциям отсюда, но когда я использую команду, vim +PluginInstall +qall терминал показывает это:

Error detected while processing /home/scorpion/.vimrc:
line    6:
E117: Unknown function: vundle#begin
line   11:
E492: Not an editor command: Plugin 'VundleVim/Vundle.vim'

Press ENTER or type command to continue

Я являюсь новым в этом. Какова возможная проблема здесь? Как я мог решить их?
Как мог я быть гарантировать, что мой Vundle установлен правильно?
