Make sure you link against python2

[RedBeard0531]

On Archlinux the default python is 3.x and you need to use python2 to get 2.x. Also need to include from /usr/lib/python2.7 not /usr/lib/python3.3m. Interestingly the ycm_core module compiles and loads fine as Py3 but ycm.py won't as it uses Py2 syntax. The error message in vim for this case incorrectly suggests that a missing libclang.so is to blame.

Thanks for catching this; should be fixed now.

Issue seems to be still present.
When starting vim the following error is produced:
YouCompleteMe unavailable: requires python 2.x

python 2.7.3 is installed (also python3). vim is on version 7.3.754. ycm was build without semantic support for c family and worked very well. System is 64 bit Arch Linux 3.7.4-1.

Having same issue...

Same issue, set default python to alias to python2.7.3, still getting "YouCompleteMe unavailable: requires python 2.x"

python --version
Python 2.7.3

vim
YouCompleteMe unavailable: requires python 2.x

Still having this issue

@frankyjuang what is the output of vim --version?

[pinkisemils]

Updated 5 minutes ago, and python/ycm/base.py and python/ycm/vimsupport.py still reference python instead of python2.
Changing the shebang to use
#!/usr/bin/env python2
instead of
#!/usr/bin/env python
should not be that hard ;)

[micbou]

Changing those shebangs would do nothing. In fact, we should remove them. There are only useful for the install.py and run_tests.py scripts.

Could this be fixed for install.py and run_tests.py? This issue has been open for two years, even if it's a small change to make.
