Python gTTS不保存MP3文件

我想用Python创建一个人工智能程序。我发现我需要GTT，但它不能保存mp3文件。请帮帮我

#gtts is imported
def talkToMe(audio, lgg = 'en'):
    #print(audio)
    tts = gTTS(text = audio, lang = lgg)
    #tts.save('audio.mp3') #doesn't work
    with open("audio.mp3") as fp: #doesn't work
        tts.write_to_fp(fp)
    os.system('mpg123\mpg123.exe audio.mp3')

---

将上面的文件另存为text_2_speech.py作为示例。我已经尝试过了，它工作正常。从命令行输入python-W ignore text_2_speech.py，然后将文件另存为当前目录中的audio.mp3

这里有什么帮助吗？B4问这里我看了这篇文章，但它没有帮助我，你也可以试试。pip卸载gTTs令牌，这将卸载gTTs令牌版本==1.1.1。并且再次执行pip安装gTTs令牌，它将安装新版本的gTTs令牌==1.1.2
