ModuleNotFoundError：没有名为'pyttsx3.drivers'的模块（使用pyinstaller编译的文件），但是可以作为未编译的文件正常工作

Question

我使用pyinstaller编译了程序，未编译时python文件工作正常，但是在编译和测试它时抛出错误。

这是完整的错误，我认为可能是因为pyinstaller

Traceback (most recent call last):
  File "site-packages\pyttsx3\__init__.py", line 20, in init
  File "c:\python37\lib\weakref.py", line 137, in __getitem__
    o = self.data[key]()
KeyError: 'sapi5'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "song_dl.py", line 25, in <module>
    engine = pyttsx3.init('sapi5')
  File "site-packages\pyttsx3\__init__.py", line 22, in init

Answer 1

看看文档的When things went wrong部分特别是Listing hidden imports

似乎pyinstaller无法“知道”它需要添加此特定模块，因此您需要明确指定它

可能类似

$ pyinstaller --hidden-imports=pyttsx3.drivers song_dl.py
