处理BufRead Auto命令时检测到unix vim错误

Question

我是一个新的vim用户，按照这个指南，让vim自动缩进python代码并标记不必要的空白：https://realpython.com/blog/python/vim-and-python-a-match-made-in-heaven/#vim-extensions

我遇到的问题是当我在一个.py文件上启动vim时收到这个错误：Error detected while processing BufRead Auto commands for "*.py": E28: No such highlight group name: BadWhitespace

这个错误我注释掉了以下几行：

" Flag unnecessary whitespace                                           
au BufRead,BufNewFile *.py,*.pyw,*.c,*.h match BadWhitespace /\s\+$/   <- this line   

" UTF8 Support                                                          
set encoding=utf-8                                                      
" Proper PEP8 Identation                                                
au BufNewFile,BufRead *.py                                              
    \ set tabstop=4                                                     
"    \ set softtabstop=4      <-- this line                                          
    \ set shiftwidth=4                                                  
    \ set textwidth=79                                                  
    \ set expandtab                                                     
    \ set autoindent                                                    
    \ set fileformat=unix         

如何修复此错误？这是我完整的.vimrc文件：

Answer 1

或者从here：

" Use the below highlight group when displaying bad whitespace is desired.
highlight BadWhitespace ctermbg=red guibg=red

" Display tabs at the beginning of a line in Python mode as bad.
au BufRead,BufNewFile *.py,*.pyw match BadWhitespace /^\t\+/

" Make trailing whitespace be flagged as bad.
au BufRead,BufNewFile *.py,*.pyw,*.c,*.h match BadWhitespace /\s\+$/
