这行rubypress代码:

:type => MIME::Types.type_for(FILENAME).first.to_s,

正在发生以下错误:

NameError: uninitialized constant MIME

整个街区是:

FILENAME='myFile.png'
wp.uploadFile(:data => {
    :name => FILENAME,
    :type => MIME::Types.type_for(FILENAME).first.to_s,
    :bits => XMLRPC::Base64.new(IO.read(FILENAME))
    })

有什么建议问题是什么？
