我正在使用cygwin在windows中安装hadoop0.19.1。格式化namenode时，出现以下错误。。

: No such file or directory
./hadoop: line 43: $'\r': command not found 
: No such file or directorycot/hadoop-0.19.1/bin 
./hadoop: line 45: $'\r': command not found 
./hadoop: line 47: syntax error near unexpected token `$'in\r'' 
'/hadoop: line 47: `case "`uname`" in..."

请告诉我一个解决办法！
