ModuleNotFoundError: No module named 'pyttsx3.drivers' (File Compiled with pyinstaller), but working fine as uncompiled

我使用 pyinstaller 编译了我的程序，python 文件在未编译时工作正常，但在编译和测试时抛出错误。

这是完整的错误，我想这可能是因为 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:

    engine = pyttsx3.init('sapi5')

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

看起来 pyinstaller 无法"know"它需要添加这个特定的模块，因此您需要明确指定它

可能类似于

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

首先，转到安装 python.exe 文件的文件夹，然后转到此目录：

\Lib\site-packages\PyInstaller\hooks

进入目录前必须先安装pyinstaller。 然后查看hooks文件夹，看看是否有一个名为：

的文件

hook-pyttsx3.py

文件很可能不存在。 因此，您必须在 hooks 文件夹中创建 hook-pyttsx3.py，并在必须写入的文件中创建：

""" pyttsx3 imports drivers module based on specific platform. Fount at https://github.com/nateshmbhat/pyttsx3/issues/6 """


hiddenimports = [
    'pyttsx3.drivers',
    'pyttsx3.drivers.dummy',
    'pyttsx3.drivers.espeak',
    'pyttsx3.drivers.nsss',
    'pyttsx3.drivers.sapi5', ]

保存文件。 然后 运行 你的代码。 问题将得到解决（至少它对我有用。） 出现这个问题是因为pyinstaller没有正式更新到完全使用python 3.8，所以一些模块的hooks丢失了

@Lakshya 给出的答案是正确的，但仅限于 Windows 环境。

对于使用Anaconda的用户，路径会发生变化。为了新用户的简单起见，这里是更新后的路径。

在这里，我使用的是一个名为 voice 的虚拟环境，因此它与 python3.7 一起在 envs/voice/ 中。这些可能因您的本地路径而异。

/anaconda3/envs/voice/lib/python3.7/site-packages/PyInstaller/hooks

如果你不使用虚拟环境，它看起来像，

/anaconda3/lib/python3.8/site-packages/PyInstaller/hooks

然后只需添加文件 hook-pyttsx3.py。
