如何在Ubuntu14.04+上编译同时支持python2和python3的vim？
详细请见：

It seems on Debian-based systems (at least) you can't have your cake and eat it too. It's either Python 2 or Python 3. Due to how the Python libraries are built, you can only use one variant within a Vim session. You can build with both, but if Python 2 is called in Vim, then Python 3 cannot be called in the same session, and vice versa. On Arch Linux as well, Vim is only compiled with one of Python 2 (vim, gvim) or Python 3 (vim-python3, gvim-python3).
To rebuild the Vim that the repositories provide:
sudo apt-get build-dep vim apt-get source vim cd vim-* # it will be vim-7.4.something
Edit debian/rules and replace:
ALLINTERPFLAGS+=--enable-pythoninterp --with-python-config-dir=$(shell python-config --configdir) ALLINTERPFLAGS+=--disable-python3interp
With:
ALLINTERPFLAGS+=--enable-pythoninterp=dynamic --with-python-config-dir=$(shell python-config --configdir) ALLINTERPFLAGS+=--enable-python3interp=dynamic --with-python3-config-dir=$(shell python3-config --configdir)
Then run:
DEB_BUILD_OPTIONS=nocheck dpkg-buildpackage -rfakeroot -us -uc -b
(备注：这里在原教程中是 dpkg-buildpackage -us -uc ，但是在我的ubuntu上运行失败，上面的是运行成功的)
Have lunch. (Or tea if you used -j $(nproc).)
Now, multiple .deb files will have been created in the parent directory. To see which:
cd .. ls vim*.deb
Along with the particular variant you want to install (vim, vim-gnome, vim-gtk, etc.), you'll have to install vim-common_*.deb, vim-runtime_*.deb, and for the GUI versions, vim-gui-common_*.deb. For example, with vim-gnome, and the current version of vim in the repositories:
sudo dpkg -i vim-gnome_7.4.052-1ubuntu3_amd64.deb vim-common_7.4.052-1ubuntu3_amd64.deb vim-gui-common_7.4.052-1ubuntu3_all.deb vim-runtime_7.4.052-1ubuntu3_all.deb
Then:
$ vim --version | grep python +cryptv +linebreak +python/dyn +viminfo +cscope +lispindent +python3/dyn +vreplace
The pi-rho/dev PPA builds Vim in this fashion, so you cna use the PPA instead of manually building it.
