I tried running CodeQueryMakeDB and got:
Making DB ...
Error detected while processing function codequery#make_codequery_db:
line 45:
E117: Unknown function: job_start
E15: Invalid expression: job_start(['/bin/sh', '-c', shell_cmd], options)
Press ENTER or type command to continue
I'm using neovim on OSX. It seems like it could be a similary issue to what I see here
