Cannot open terminal ini nvim

Question

I installed Plugin terminal using the vim-terminal plugin and try to execute :TerminalSplit bash but before the terminal open I got a warning message.

Python 2 interface is not installed, using Python 3 instead
Warning: Global CursorHoldI and CursorMovedI autocommands may cause Terminal to run slowly
Press ENTER or type command to continue

after I clicked ENTER, the terminal will appear but it does not give any response when I type any command. Can someone help me with this? here is my init.vim. I confuse where is the problem

:set number
:set autoindent
:set tabstop=4
:set shiftwidth=4
:set smarttab
:set softtabstop=4
:set mouse=a

Answer 1

It seems like that the plugin is very old and isn't probably up to date anymore. Since you're using neovim I'd recommend to pick one of the terminal-plugins from this list. You could give toggleterm a try for example.
