Question

我成功安装了pip install pyttsx3的pyttsx3，并编写了以下代码：

import pyttsx3 

def speak(text):
     engine = pyttsx3.init()
     engine.say(text)
     engine.runAndWait()
text = 'hello'
speak(text)

运行代码时，出现以下错误：

Traceback (most recent call last):
File "/home/walter197/.local/lib/python3.6/site-packages/pyttsx3/__init__.py", line 20, in init
eng = _activeEngines[driverName]
File "/usr/lib/python3.6/weakref.py", line 137, in __getitem__
o = self.data[key]()
KeyError: None

During handling of the above exception, another exception occurred:

  self._handle = _dlopen(self._name, mode)
  OSError: libespeak.so.1: cannot open shared object file: No such file or directory

知道我在安装之前已更新了软件包，并且我的Python版本是3.6.9。请告诉我有什么问题，我该如何解决？

您的系统上没有安装必需的库，因此错误的最后一部分：

libespeak.so.1错误：找不到这样的文件或目录。

您可以尝试安装espeak：

sudo apt install espeak

或该库的开发版本：

sudo apt install libespeak-dev

如果您对多语言版本感兴趣：

sudo apt install libespeak-ng-libespeak-dev

在Linux Mint上安装pyttsx3
