Install neovim from package

Neovim has been added to a Ubuntu PPA. For more information check neovim/neovim.

    sudo apt-get install software-properties-common
    sudo add-apt-repository ppa:neovim-ppa/unstable
    sudo apt-get update
    sudo apt-get install neovim

Create a symlink to our config-folder for Neovim:

    ln -s ~/.vim ~/.config/nvim

Install neovim from source

Check the build prerequisites, e.g. recent verions of CMake and (Clang or GCC)

    sudo apt-get install ninja-build libtool libtool-bin autoconf automake cmake g++ pkg-config unzip

Build and install Neovim:

    git clone https://github.com/neovim/neovim ~/.local/opt/neovim
    cd ~/.local/opt/neovim
    make
    sudo make install

Make nvim binary available via PATH:

    ln -s ~/.local/opt/neovim/bin/nvim ~/.local/bin/nvim
    echo 'export PATH=$PATH:$HOME/.local/bin/' >> ~/.bashrc

Set TERM for neovim:

    echo 'export TERM="xterm-256color"' >> ~/.bashrc

If you like, you can set up an alias for nvim:

    echo "alias 'vi'='nvim '" >> ~/.bashrc

Now reload the bash-settings:

    source ~/.bashrc

And create a symlink to our config-folder for Neovim:

    ln -s ~/.vim ~/.config/nvim

Make Python available in Neovim

Test whether Neovim is able to use Python:

    nvim
    :python print "hello"

If this does not work, you can install the Python package neovim manually. For more information you can check the Neovim documentation on Python in Neovim.

    sudo apt-get install python-dev python-pip
    sudo pip2 install neovim

Typically /usr/bin contains a symbolic link python2 to the latest Python 2 version. If there is no such symlink, you have to change the path in vimrc:line19.

    let g:python_host_prog = '/path/to/your/python2'
