has('patch330') is 1, so I think it match the requirement in README vim7.3 or higher. Only support vim7.4.330 or higher after v1.01. but:

when start LeaderF for first time: Error detected while processing function leaderf#Any#start..leaderf#LfPy: line 1: Traceback (most recent call last): File "", line 1, in File "/home/qiuyuankun/.vim/bundle/LeaderF-master/autoload/leaderf/python/leaderf/anyExpl.py", line 838, in start the_args.start(arguments, *args, **kwargs) File "/home/qiuyuankun/.vim/bundle/LeaderF-master/autoload/leaderf/python/leaderf/anyExpl.py", line 756, in _default_action manager.startExplorer(win_pos[2:], *args, **kwargs) File "/home/qiuyuankun/.vim/bundle/LeaderF-master/autoload/leaderf/python/leaderf/fileExpl.py", line 827, in startExplorer super(FileExplManager, self).startExplorer(win_pos, *args, **kwargs) File "/home/qiuyuankun/.vim/bundle/LeaderF-master/autoload/leaderf/python/leaderf/manager.py", line 2774, in startExplorer self._getInstance().enterBuffer(win_pos, not isinstance(content, list)) File "/home/qiuyuankun/.vim/bundle/LeaderF-master/autoload/leaderf/python/leaderf/instance.py", line 1214, in enterBuffer self._createBufWindow(win_pos) File "/home/qiuyuankun/.vim/bundle/LeaderF-master/autoload/leaderf/python/leaderf/instance.py", line 931, in _createBufWindow lfEval("get(g:, 'Lf_PopupColorscheme', 'default')"))) vim.error: Vim(highlight):E421: Color name or number not recognized: ctermfg=-1 ctermbg=24 Error detected while processing function leaderf#Any#start: line 4: E171: Missing :endif Press ENTER or type command to continue

I don't know where ctermfg=-1 come from. Do you have any customized configuration?

I have no configuration about ctermfg in my .vimrc, I grep "ctermfg" from my .vim dir and I found only vim-airline, leaderf and rainbow, these plugin dir show results. But there is no ctermfg=-1 from the grep results. I found a similar issue about this https://github.com/Yggdroot/LeaderF/issues/682

Fixed.
