APScheduler(高级Python调度程序)ImportError:没有名为scheduler的模块

Question

我有以下导入错误

"ImportError:没有名为scheduler的模块"

当我运行以下python脚本时:

"""
Demonstrates how to use the blocking scheduler to schedule a job that execute$
"""

from datetime import datetime
import os

from apscheduler.scheduler import BlockingScheduler


def tick():
 print('Tick! The time is: %s' % datetime.now())


if __name__ == '__main__':
 scheduler = BlockingScheduler()
 scheduler.add_job(tick, 'interval', seconds=3)
 print('Press Ctrl+{0} to exit'.format('Break' if os.name == 'nt' else 'C'$

try:
    scheduler.start()
except (KeyboardInterrupt, SystemExit):
    pass

我已经安装了APS调度程序:sudo pip install apscheduler

我也升级了使用:sudo pip install apscheduler --upgrade还使用"sudo apt-get install update && sudo apt-get upgrade"升级了我的系统

Answer 1

我有同样的问题,但后来我发现,

我安装了apscheduler版本3然后我转移到版本2.1.2使用,

pip uninstall apscheduler
pip install apscheduler==2.1.2

在切换到版本2.1.2之前只需要结帐,如果你想使用版本3中添加的额外功能.在我的情况下,我不想要太多.

你的导入是错误的.它应该是:

from apscheduler.schedulers.blocking import BlockingScheduler

这里的参考示例:

"""
Demonstrates how to use the blocking scheduler to schedule a job that executes on 3 second
intervals.
"""

from datetime import datetime
import os

from apscheduler.schedulers.blocking import BlockingScheduler


def tick():
    print('Tick! The time is: %s' % datetime.now())


if __name__ == '__main__':
    scheduler = BlockingScheduler()
    scheduler.add_job(tick, 'interval', seconds=3)
    print('Press Ctrl+{0} to exit'.format('Break' if os.name == 'nt' else 'C'))

    try:
        scheduler.start()
    except (KeyboardInterrupt, SystemExit):
        pass
