使用 pyinstaller 创建可执行文件时 python 的 plyer 库出现问题

Question

I am trying to generate a notification in windows using plyer library in python. It works fine when the python script is run. But when I try to create an executable file using pyinstaller and run the executable I keep getting this error

Traceback (most recent call last):
  File "site-packages\plyer\utils.py", line 96, in _ensure_obj
ModuleNotFoundError: No module named 'plyer.platforms'
Traceback (most recent call last):
  File "in_time.py", line 131, in <module>
  File "site-packages\plyer\facades\notification.py", line 84, in notify
  File "site-packages\plyer\facades\notification.py", line 90, in _notify
NotImplementedError: No usable implementation found!

This is the snippet of the code

from plyer import notification

    notification.notify(
       title='9 hours Completed',
       message='You have successfully completed 9hrs for the day',
       app_name='In Time App',
       app_icon='Time3.ico'
    )

Answer 1

使用pyinstaller创建可执行文件时，将其添加到命令：

--hidden-import plyer.platforms.win.notification

Answer 2

add following hidden import to spec file

a = Analysis(
   ...
   hiddenimports=['plyer.platforms.win.notification'],
   ...

Answer 3

pyinstaller --onefile --hidden-import plyer.platforms.linux.notification filename.py 

if you are using linux

plyer.platforms.win.notification 

if you are using win There are also ios, macos, android platforms available so if you are using that, you may want to use those. If it doesn't work then you may want to check the plyer.platforms.<your_flatform> directory and see if notifications.py is existing or not.

Answer 4

I am using Windows and the solution with hiddenimports didn't work for me.

There's an other solution by copying the plyer package from python site_packages to the application directory as described here: https://stackoverflow.com/a/64448486/11362192

The copying of this package can also be automated. To do this, add the original path to the plyer package as datas to the spec file:

site_packages_dir = 'C:/Python/Python310/Lib/site-packages/'

a = Analysis(
   ...
   datas=[(site_packages_dir+'plyer', './plyer')],
   ...
