python3使用pyinstaller打包apscheduler出的错

2024-08-21 22:26:18   214人阅读

　　本来只是想用Python做一个定时任务小工具在服务器上运行，可是服务器在隔离区，各种禁止上外网，使用pip导出列表那种下载库的方法不管用，导致Python的各种库都下不到，官网离线下载又各种缺依赖，好气啊。后来查了一下，原来还有pyinstaller这种好东西，将需要的库和程序打包成一个可运行的程序，这正是我需要的。　　

　　为了测试pyinstaller，主要遇到了两个错误，一个是pkg_resources.DistributionNotFound，一个是ImportError: No module named。下面又开始说起，需要看主要解决办法的可以看大标题。

　　先搞一个测试小程序吧，这个程序很简单，每5s打印一次a：

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

from apscheduler.schedulers.blocking import BlockingScheduler


def p():
    print("a")

if __name__ == ‘__main__‘:
    scheduler = BlockingScheduler()
    scheduler.add_job(p, "cron",second=‘1/5‘)

    try:
        scheduler.start()
    except Exception as e:
        pass

使用pyinstaller打包成一个单独可运行的文件：

pyinstaller -F test1.py

pkg_resources.DistributionNotFound

可是出错了，提示找不到APScheduler，可我已经下载了啊，苦闷。

Traceback (most recent call last):
  File "test1.py", line 4, in <module>

  File "site-packages\pkg_resources\__init__.py", line 829, in resolve
pkg_resources.DistributionNotFound: The ‘APScheduler‘ distribution was not found
 and is required by the application
Failed to execute script test1

我查了一下，官方Issues给出了答案https://github.com/pyinstaller/pyinstaller/issues/1713

大概就是创建一个hook-ctypes.macholib.py，内容是：

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

from PyInstaller.utils.hooks import copy_metadata

datas = copy_metadata(‘apscheduler‘)

然后打包的时候添加--additional-hooks-dir=

pyinstaller -F test1.py --additional-hooks-dir=.

可是，又出现了一个新问题ImportError: No module named

ImportError: No module named

Traceback (most recent call last):
  File "site-packages\apscheduler\schedulers\base.py", line 880, in _create_plug
in_instance
KeyError: ‘cron‘

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "test1.py", line 14, in <module>
  File "site-packages\apscheduler\schedulers\base.py", line 411, in add_job
  File "site-packages\apscheduler\schedulers\base.py", line 905, in _create_trig

  File "site-packages\pkg_resources\__init__.py", line 2235, in resolve
ImportError: No module named ‘apscheduler.triggers.cron‘
Failed to execute script test1

pkg_resources.DistributionNotFound问题好像解决了，但又来了一个新问题ImportError: No module named

看描述好像是cron哪里出了问题，把CronTrigger单独新建，修正后：

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from apscheduler.schedulers.blocking import BlockingScheduler
from apscheduler.triggers.cron import CronTrigger


def p():
    print("a")

if __name__ == ‘__main__‘:
    scheduler = BlockingScheduler()
    trigger = CronTrigger(second=‘1/5‘)
    scheduler.add_job(p, trigger)

    try:
        scheduler.start()
    except Exception as e:
        pass

经过上面修改后，应该可以正常运行了。如果你也有这样的问题，看看我的经验能不能帮到你？
