termux: pkg install python3
termux: pkg install nodejs
termux: pkg install vim-python
termux: pkg install cmake

Then install Vim Plug (using curl command for unix), something like:

1
curl -fLo ~/.vim/autoload/plug.vim --create-dirs     https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

Then add these to ~/.vimrc: ====> see the end of this file

Then clone YouCompleteMe to ~/.vim/plugged:

1
git clone https://github.com/ycm-core/YouCompleteMe.git ~/.vim/plugged

Then manually cd to YouCompleteMe and complie it with

1
python3 install.py --ts-completer

The tail --ts-completer enables JS support, can add another lang.

If error occur, try below instructions.

I met an error related to atomic

Then Google, I found a related discussion here:

I delete ~/.cache/pip and recompile with python3 install.py --ts-completer

Then it works.
