Python checkers do not work with macvim

[aj8k]

Hi! Syntax checking does not work for me at all. Vim 7.4, pylint 1.2.1 Turned on in vimrc let g:syntastic_python_checkers = ['pylint'] Output of :SyntasticInfo

Syntastic: active mode enabled
Syntastic version: 3.4.0-92
Info for filetype: python
Available checker(s): pylint python
Currently enabled checker(s): pylint

But no errors appeared after saving file or manual check run. Here is output of direct pylint check:

$ pylint one.py
No config file found, using default configuration
************* Module 123.one
C:  1, 0: Missing module docstring (missing-docstring)
E:  3, 0: Module 'zmq' has no 'nononon' member (no-member)
C:  4, 0: Missing function docstring (missing-docstring)
W:  5, 4: Statement seems to have no effect (pointless-statement)
E:  5, 4: Undefined variable 'sf' (undefined-variable)

Please open a Python file, set g:syntastic_debug to 3, run the checker, and post the output of :mes.

Sorry for delay. Here is output:

Your pylint crashes.

Thanx for helping in diagnostic. Find solution by simple googling. Can be found by next link: http://patrick.arminio.info/blog/2012/02/fix-valueerror-unknown-locale-utf8/

To cut a long story short I just added next lines to ~/.bash_profile and that helps ('en_US.UTF-8' is my locale):

export LC_COLLATE="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
export LC_MESSAGES="en_US.UTF-8"
export LC_MONETARY="en_US.UTF-8"
export LC_NUMERIC="en_US.UTF-8"
export LC_TIME="en_US.UTF-8"
export LC_ALL=
