python 保存 excel文件时报错：报错

我的参考网上别人的代码的，在我本机子上(win7)都可以

到了公司的服务器上(djingo/linux) 就报错 提示在  save的时候报：

'ascii' codec can't decode byte 0xe5 in position 0: ordinal not in range(128)

代码如下：  ( 我本机和公司机器上的主要代码相同， 就是 保存的路径完全不同！！！)

                         公司路径打印出来：/项目名/xx/xxx/info.xls(名子表示个意思,实际全英文)

class Try:
    def xls():
        #xls info
        wbk=xlwt.Workbook()
        sheet=wbk.add_sheet('sheet 1')
        #connect Info
        try:
           
            conn = MySQLdb.connect('localhost','root','ok','smyw_edit_server')
            cursor = conn.cursor()
            sql='select * from ser_user'
           
            #获取要打印的列名
            columnName=[u'编号',u'用户名',u'密码',u'注册时间',u'最后一次登录时间',u'是否启用']
            #获取列数
            columnLen=len(columnName)
            #打印出标题
            for i in range(columnLen):
                    sheet.write(0,i,columnName[i])
           
            #执行sql       
            cursor.execute(sql)
            #获取到查询得到的数据
            dataInfo=cursor.fetchall()
            dataLen = len(dataInfo)
            rowLine=0
            #排个顺序
            for line in range(dataLen):
                    lineInfo=dataInfo[line]
                    rowLine+=1
                    columnLine=0
                    #print line
                    #按每行打印
                    for row in lineInfo:
                            if type(row)==str:
                                row=row.encode('utf-8')
                                #print row
                            sheet.write(rowLine,columnLine,row)
                            columnLine+=1
           
            #print table
            #保存打印的excel数据
            wbk.save('c:%s.xls' % 'info')
            #print xlwt.Workbook()
            #打开打印的excel数据
           
            cursor.close()
            conn.commit()
            conn.close()
            sys.exit(1)
        except Exception,e:
            print e
        finally :
            print 'over!'
    if __name__=='__main__':
            xls()
