After updated to snapshot 109, every time I start vim and open a python script for the 1st time, error occurs in the buffer below:

Error: jedi-vim failed to initialize Python: jedi#setup_py_version: Vim(pyfile):E887: Sorry, this command is disabled, the Python's site module could not be loaded. (in function jedi#init_python[3]..66_init_python[48]..jedi#setup_py_version, line 16)

Also, jedi does not work, navigation between python codes is not capable.

If I use the system default vim, or snapshot 108, everything works fine.
