ImportError:libportaudio.so.2:无法打开共享对象文件:raspberry-pi4中没有这样的

我的代码：

import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone() as source:
print("talk")
audio_text = r.listen(source)
print("time over")

try:
text = r.recognize_google(audio_text)
print("converting the audio text into transript")
print(text)
except:
print("Run again")

几乎我检查了所有可能的

发生错误

Could not import the PyAudio C module '_portaudio'.
Traceback (most recent call last):

在处理上述异常的过程中，发生了另一个异常：
