运行Python crontab脚本时出现错误

Question

我想每1分钟运行一次python脚本。脚本运行完美，不会引起任何错误。对于cron作业，我正在使用ThisPython CronTab

  I am getting below error while run mycronjob.py  file

  Traceback (most recent call last):
  File "cronstart.py", line 6, in <module>
  my_cron.write()
File "/home/myname/.local/lib/python3.6/site-packages/crontab.py", line 338, in write
filed, path = tempfile.mkstemp()
 AttributeError: module 'tempfile' has no attribute 'mkstemp'
Error in sys.excepthook:

     class addbase(tempfile._TemporaryFileWrapper):
      AttributeError: module 'tempfile' has no attribute '_TemporaryFileWrapper'
     Original exception was:
     Traceback (most recent call last):
  File "cronstart.py", line 6, in <module>
my_cron.write()
    File "/home/myname/.local/lib/python3.6/site-packages/crontab.py", line 338, in write
    filed, path = tempfile.mkstemp()
   `enter code here`    AttributeError: module 'tempfile' has no attribute 'mkstemp'

我的cron运行文件代码：

  from crontab import CronTab  
  my_cron = CronTab(user='Myuser name')
  job = my_cron.new(command='python3 sample.py')
  job.minute.every(1)
  my_cron.write()

sample.py只是print（“ Printing cron job”）
