Completion for JS + Flow

[ghost]

I install
roxma/nvim-completion-manager
roxma/ncm-flow
roxma/nvim-cm-tern (run npm i)

but completion does not work...

In :scriptname I see

 64: ~/.cache/nvim/dein/.cache/init.vim/.dein/autoload/cm.vim
 65: ~/.cache/nvim/dein/.cache/init.vim/.dein/autoload/cm/snippet.vim
 66: ~/.cache/nvim/dein/.cache/init.vim/.dein/autoload/cm/sources/css.vim

tern-server is not running.

Could you write a little config needed for work js + flow if it is necessary?
