tilecache切图请教?报错

我做tilecache切图遇到问题：

1）tilecache/index.html：文件修改切图vmap0，可以的，缓存切图basic成功

2）http://127.0.0.1:80/cgi-bin/mapserv.exe?MAP=F:/ms4w/tutorial/htdocs/example1-1.map&LAYERS=ALL&MODE=MAP，可以的，看到相应的图层信息

但是.....以下是有问题的：tilecache切自己定义的map文件states图层（map文件由官网下载）

cmd中输入“python "F:/ms4w/Apache/htdocs/tilecache/tilecache_seed.py" states 0 7

”报错如下：python cannot open file error 22 invalid argument

查找错误：断点调试tilecache_seed.py报错了

tilecache.cfg定义：

[states]

type=WMS

url=http://127.0.0.1:80/cgi-bin/mapserv.exe?MAP=F:/ms4w/tutorial/htdocs/example1.map

layers=states

extension=png

bbox=-97.238976,41.619778,-82.122902,49.385620

size=256,256

其中提到：

2）Content-Type Header: application/vnd.ogc.se_xml

3）msWMSDispatch(): WMS server error. WMS request not enabled. Check wms/ows_enable_request settings.

第一个是说，不能将data写入image，报错信息中也提示了data返回为空

第二个看不太明白了

第三条说，url有问题。是mapserver服务有问题，可是输入map文件getmap是可用的？

将它提示的错误url“http://127.0.0.1:80/cgi-bin/mapserv.exe?MAP=F:/ms4w/tutorial/htdocs/example1.map&layers=states&styles=&service=WMS&width=256&format=image%2Fpng&request=GetMap&height=256&srs=EPSG%3A4326&version=1.1.1&bbox=-97.238976%2C41.619778%2C-89.680939%2C49.177815”输入，出现下载mapserver.exe的下载页面？？？

糊涂了，看不出来哪里出了问题？

tilecache提示的错误信息是url有问题，是这样的吗？怎么跟踪问题？我哪里操作出了问题呢？
