PermissionError：[Errno 13]权限被拒绝：'Payment Report.xls'

Question

我有这段代码来创建一个.xls文件来存储python数据。当我在服务器或本地中运行它时，出现此错误： PermissionError：[Errno 13]权限被拒绝：“ Payment Report.xls”

 file.close()
     row += 2
     date = datetime.now()
     name = ('Payroll Payment Report_'+ str(date)+'.xls')
     filename = ('Payment Report.xls')
     workbook.save(filename)
     file = open(filename, "rb")
     file_data = file.read()
     out = base64.encodestring(file_data)
     self.write({'file_name': out, 'filexcel': name})

     return {
             'type': 'ir.actions.act_window',
             'res_model': 'payslip.hr.payment.xls',
             'view_mode': 'form',
             'view_type': 'form',
             'res_id': self.id,
             'target': 'new', }
