保存时报错解决办法:
wr工具此时执行的是spawn,需要执行的是exec，正确的代码为：wr --exec "lessc duang.less duang.css" duang.less。详解如下：
exec:
the command will not be parsed, as will be run as given
should handle i/o redirection shell operators
stdout and stderr output will be buffered until the command is complete
spawn:
the command will be parsed into space separated tokens, probably misinterpreting any quotes you have in your command
will not handle i/o redirection shell operators
stdout and stderr output will not be buffered
