Не удалось установить Vundle?

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

Error detected while processing /home/scorpion/.vimrc:

Press ENTER or type command to continue

Я новичок в этом. В чем здесь возможная проблема? Как я мог их решить?
Как я могу убедиться, что мой Vundle установлен правильно?
