[SOLVED] Why do I need to run PluginInstall every time to use Black inside vim?

Why do I need to run PluginInstall every time to use Black inside vim?

I just installed Black from:

Plugin 'ambv/black', {'rtp': 'vim'}

using Vundle.

I am not able to use the Black command without running PluginInstall.

Is this a bug?

The plugin is here

My .vimrc looks like this:

set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'gmarik/Vundle.vim'
Plugin 'ambv/black', {'rtp': 'vim'}
call vundle#end()

Solution

after reading the Vundle documentation it seems you are missing some required lines in your .vimrc

but I think the main issue is that you are changing the rtp of black, removing that works with the following .vimrc

set nocompatible             "required
filetype off                 "required

set rtp+=~/.vim/bundle/Vundle.vim

call vundle#begin()
Plugin 'VundleVim/Vundle.vim'
Plugin 'ambv/black'
call vundle#end()            " required

filetype plugin indent on    " required
