在Linux上安装pyttsx3

Question

我成功地用pyttsx3安装了pip install 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)

当我运行代码时，我会得到以下错误：

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:

File "scrap.py", line 100, in speak

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

知道我在安装之前更新了软件包，而且我的Python版本是3.6.9，请告诉我有什么问题，我如何解决它？

Answer 1

您的系统上没有安装所需的库，因此出现了最后一个错误：

libespeak.so.1错误:找不到此类文件或目录。

您可以尝试安装espeak：

sudo apt install espeak

或者库的开发版本：

sudo apt install libespeak-dev

如果您对多语言版本感兴趣，那么：

sudo apt install libespeak-ng-libespeak-dev
