How to specify Python interpreter version in VIM?
You probably don't want to (or at least should not) set
python3 as the default python interpreter for vim, as then some (most of) your plugins will become incompatible, such as
clang_complete itself, because they do not have
python3 support. Normally plugins that do support
python3 let you decide if you want to use it by adding to your
let g:syntastic_python_python_exec = 'python3'
:echo has('python') showing
0 is actually telling you that vim is perhaps not compiled with
python2. So first check the output of
vim --version and you should be able to see a list of shared libraries that your compiler has built vim against. Do you see the following? (e.g. for python 2.7):
If not (or if you see both
-lpython3.x I suggest you compile vim from source, linking it specifically to
-lpython2.x. It is not that difficult to build vim from source. First make sure to remove all your current vim installation, for instance using
aptitude you'd do:
sudo apt-get remove --purge vim vim-runtime vim-gnome vim-tiny vim-common vim-gui-common
clone vim mercurial
hg clone https://code.google.com/p/vim/ cd vim
and then run
./configure with the following flags:
./configure --with-features=huge \ --enable-cscope \ --enable-pythoninterp \ --enable-largefile \ --with-python-config-dir=/usr/lib/python2.7/config
you might also want to link against
lua if you want, and then finally run
make build make install
Here is shell script that will automate the whole process for you. This might be a bit of an overkill, but I think this is how you should handle this to not run with compatibility issues with your future packages.

In order to write C++ in Vim with plugin, Clang_complete.
After installing, this error occurs:
Error detected while processing function <SNR>14_ClangCompleteInit..<SNR>14_initClangCompletePython: clang_complete: No python support available. Cannot use clang library Compile vim with python support to use libclang
But my vim supports both python and python3.
then I check my python interpreter:
:echo has('python') # output is 0 :echo has('python3') # output is 1
So, I think the reason is my vim dynamic load python3 interpreter by default.
Can I change python interpreter? or set default dynamic load version of python?
