Multiple errors on startup.

Why does this happen and how do I fix this?

Seems like you don't have python support compiled in for your version of vim.

It appears that for Ubuntu 17.04 Zesty, apt install vim-gtk installs vim without python support, only with python3 support.

Even with python2 support, this issue persists:

I tried to solve this problem by first uninstalling vim (DANGER: take note of any files, such as your vimrc, which may be lost.). To be sure everything is uninstalled:

sudo apt-get remove *vim*

Caution: this may match some non-vim packages.

And then, compiling ViM from source:

cd /tmp && git clone https://github.com/vim/vim.git && cd vim
./configure --enable-pythoninterp --prefix=/usr
make && sudo make install

Now, when I run vim --version, the list of features shows:

...
+python    # <--- this is what we were lacking
-python3
...

Yes, it is crucial that gvim is compiled with python2 support otherwise it will not work (most source code in yavide is python2). Some distros decide to distribute and compile gvim with python3 support only, some others compile it with python2 only and the rest compile it with both python2 & python3 support. This is where the things start tearing apart.

What people can do to fix this problem is to install required dependencies in order to get gvim with python2 support. Hopefully someone will make a pull-request as well to fix the installation script.

I am on Mint 18.3 which should based on Ubuntu 16.04. I encountered the same issue on startup. My solution is: After installation, I change the yavide.desktop to use vim.gnome-py2 -g to launch yavide. Because I am using python 3 as my default python. So, before installation, I also change the "PIP_INSTALL_CMD" in install.sh to "pip2 install".

Thanks for reporting the solution back.
