情况描述：新安装的虚拟机无法打开Terminal，从应用列表中单击Terminal，左上角任务栏会出现Terminal，并且鼠标转圈，但是过一会左上角Terminal消失，就像一切都没有来过。解决办法：    CTRL + ALT + F3 进入命令行模式（需要返回桌面时CTRL + ALT + F1）    cd /etc/default    sudo nano locale    把文件中的 “en_US” 改成 “en_US.UTF-8”    保存退出    sudo locale-gen –purge    reboot 重启虚拟机

在本机先使用root用户登录mysql： mysql -u root -p"youpass" 进行授权操作： mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'youpassword' WITH GRANT OPTION; 重载授权表： FLUSH PRIVILEGES; 退出mysql数据库： exit

可在nano或者gax上面使用（已测试过） 将mp3文件转换为wav文件trans_mp3_to_wav.py 12345678from pydub import AudioSegment# 这里filepath填的是.mp3文件的名字（也可加上路径）def trans_mp3_to_wav(filepath): song = AudioSegment.from_mp3(filepath) song.export("test.wav", format="wav")trans_mp3_to_wav('test.mp3') 播放play_wav.py 12345from pydub import AudioSegmentfrom pydub.playback import playsong = AudioSegment.from_wav("test.wav")play(song)
