pyttsx3模块没有提供任何输出

Question

我的pyttsx3模块有一些问题。一开始我甚至无法初始化它，我得到了以下错误：

File "/home/emanuele/.local/lib/python3.9/site-packages/pyttsx3/__init__.py", line 20, in init
eng = _activeEngines[driverName]
File "/usr/lib/python3.9/weakref.py", line 137, in __getitem__
o = self.data[key]()
KeyError: None

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "/home/emanuele/AllInOneApp.py", line 3, in <module>
engine = pyttsx3.init()
File "/home/emanuele/.local/lib/python3.9/site-packages/pyttsx3/__init__.py", line 22, in init
eng = Engine(driverName, debug)
File "/home/emanuele/.local/lib/python3.9/site-packages/pyttsx3/engine.py", line 30, in __init__
self.proxy = driver.DriverProxy(weakref.proxy(self), driverName, debug)
File "/home/emanuele/.local/lib/python3.9/site-packages/pyttsx3/driver.py", line 50, in __init__
self._module = importlib.import_module(name)
File "/usr/lib/python3.9/importlib/__init__.py", line 127, in import_module
return _bootstrap._gcd_import(name[level:], package, level)
File "<frozen importlib._bootstrap>", line 1030, in _gcd_import
File "<frozen importlib._bootstrap>", line 1007, in _find_and_load
File "<frozen importlib._bootstrap>", line 986, in _find_and_load_unlocked
File "<frozen importlib._bootstrap>", line 680, in _load_unlocked
File "<frozen importlib._bootstrap_external>", line 850, in exec_module

File "/home/emanuele/.local/lib/python3.9/site-packages/pyttsx3/drivers/espeak.py", line 3, in <module>
import ctypes
File "/usr/lib/python3.9/ctypes/__init__.py", line 8, in <module>
from _ctypes import Union, Structure, Array
ImportError: libffi.so.8: cannot open shared object file: No such file or directory 

然后我通过运行这两个命令来解决这个问题。

pip uninstall pyttsx3

和

pip install pyttsx3==2.71

并在init函数中添加参数‘哑’。问题是，现在它运行时没有错误，但是我没有从模块中得到任何输出。

我终于找到解决办法了。请参阅下面的修复程序。

Run: sudo apt install libespeak1

解释:在ubuntu中运行pyttsx3需要 libspeak1包。
