抛出这个错误：

/home/gigachod/PycharmProjects/JarvisAI/venv/bin/python /home/gigachod/PycharmProjects/JarvisAI/main.py 
sh: 1: say: not found
PyCharm

Process finished with exit code 0

我的完整代码是：

import speech_recognition as sr
import os

def say(text):
    os.system(f"say {text}")
if __name__ == '__main__':
    print('PyCharm')
    say("Hello ASH I am JARVIS")

我用的是speech_recognition包和os包。做了一个简单的函数说，并运行它我使用bash shell。
