E117:未知函数:ale#Lint

.vimrc 文件。当我打开一个Rails应用程序时,我得到了以下错误。

rails_app/config/environments/development.rb                                                                    2,3            Top
Error detected while processing CursorHold Auto commands for "*":
E117: Unknown function: ale#Lint
Press ENTER or type command to continue

错误是从 Ale

" ALE linting events
augroup ale
  autocmd!

  if g:has_async
    set updatetime=1000
    let g:ale_lint_on_text_changed = 0
    autocmd CursorHold * call ale#Lint()
    autocmd CursorHoldI * call ale#Lint()
    autocmd InsertEnter * call ale#Lint()
    autocmd InsertLeave * call ale#Lint()
  else
    echoerr "The thoughtbot dotfiles require NeoVim or Vim 8"
  endif
augroup END

vimrc.bundles 我有下面这句话。

if g:has_async
  Plug 'w0rp/ale'
endif
