在 Ubuntu 20.04 上使用 'pyttsx3' 时遇到问题

Question

我在 Ubuntu 20.04。在 Pycharm CE 上尝试了以下代码。只是说出“Hello World”。

import pyttsx3
pyttsx3.speak("Hello World!")

得到以下显示大量错误的输出。请帮忙！

 Traceback (most recent call last):
  File "/home/masrafi/PycharmProjects/audio book/venv/lib/python3.8/site-packages/pyttsx3/__init__.py", line 20, in init
    eng = _activeEngines[driverName]
  File "/usr/lib/python3.8/weakref.py", line 131, in __getitem__
    o = self.data[key]()
KeyError: None

 During handling of the above exception, another exception occurred:

Answer 1

正如错误指出的那样：OSError: libespeak.so.1: cannot open shared object file: No such file or directory，必须使用

安装该库

sudo apt install libespeak-dev

Answer 2

就在运行终端线下面

sudo apt install libespeak1
