Python 简单教程变量未定义问题

Question

所以我在 youtube 上关注了一个简单的教程，但无论我做什么，我总是遇到同样的问题。

这是我使用的代码。

import speech_recognition as sr
import pyttsx3


voices = []
engine = pyttsx3.init()

voices = engine.getProperty('voices')
for voice in voices:
    print(voice.id)

我正在用 sublimeText3 写这个。每次我构建这个，我都会得到同样的错误。

File "C:\Users\This PC\Desktop\Py\introTest.py", line 14, in voices = engine.getProperty('voices') NameError: name 'engine' is not defined

不确定为什么说 "engine" 未定义。我明明定义了下试试。任何帮助将不胜感激。

删除 try/excepts 后我有很多新错误。这是构建日志。

Traceback (most recent call last): File "C:\Users\This PC\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pyttsx3__init__.py", line 44, in init eng = _activeEngines[driverName] File "C:\Users\This PC\AppData\Local\Programs\Python\Python37-32\lib\weakref.py", line 137, in getitem o = self.datakey KeyError: None

During handling of the above exception, another exception occurred:

Answer 1

尝试在try/catch块中输入导入，并检查导入后是否未定义，因此抛出异常。查看模块官方网站，查看您的控制台日志以查找其中的一些错误，

修复了可能的错误： No module named win32com.client No module named win32 No module named win32api

试试这个

pip install pypiwin32

另外显示您的日志，以便我们更好地了解情况！

Answer 2

看到完整的错误日志转储（没有 try 块隐藏错误）后，最后一位是文本：

line 3, in import win32com.client ModuleNotFoundError: No module named 'win32com' [Finished in 0.1s]

我建议查看。（提示：它告诉你你缺少 pyttsx3 依赖的模块）

您正在尝试分配 engine = pyttsx3.init()，但 when/if 失败，然后您声明 voices = engine.getProperty('voices')。但由于 try 块失败，engine 尚未声明。

下面，我分配 engine = None，并跳过 try 块中的 else；而是使用条件来确定它是否为 None（它在创建 engine 时工作正常）。

import speech_recognition as sr
import pyttsx3


voices = []
engine = None

try:
    engine = pyttsx3.init()
except ImportError:
    print('Import Issue')
except RuntimeError:
    print('Runtime Issue')

if (engine is not None):
    voices = engine.getProperty('voices')
    for voice in voices:
        print(voice.id)
else:
    print("Something went wrong")

Answer 3

import speech_recognition as sr
import pyttsx3

voices = [] 
try:
    engine = pyttsx3.init()
except ImportError:
    print('Requested driver is not found')
    engine = None
except RuntimeError:
    print('Driver fails to initialize')
    engine = None

if engine is None:
    print('Something went wrong')

else:
    voices = engine.getProperty('voices')
    for voice in voices:
        print(voice.id)

Answer 4

在 Ubuntu 我遇到了同样的问题。有史以来最简单的修复：

sudo apt install libespeak1

Answer 5

嗨，我遇到过类似的问题，这就是我如何轻松改变声音的方法

import pyttsx3

voices = []

eng = pyttsx3.init()

voices = eng.getProperty('voice')

eng.setProperty('voice',voices[1].id)
eng.say("Some text here")
eng.runAndWait()
