我正在使用var audioPlayer : AVAudioPlayer!
@IBAction func playButtonClicked(sender : AnyObject){
let dispatchQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)
dispatch_async(dispatchQueue, {
if let data = NSData(contentsOfFile: self.audioFilePath())
{
do{
let session = AVAudioSession.sharedInstance()
try session.setCategory(AVAudioSessionCategoryPlayback)
try session.setActive(true)
self.audioPlayer = try AVAudioPlayer(data: data)
//self.audioPlayer.delegate = self
self.audioPlayer.prepareToPlay()
self.audioPlayer.play()
}
catch{
print("\(error)")
}
}
});
}
func audioFilePath() -> String{
let filePath = NSBundle.mainBundle().pathForResource("mySong", ofType: "mp3")!
return filePath
}
和pymongo。
当我做的时候
mongoengine在我的import mongoengine
目录中
我收到以下错误：
/home/ubuntu/project在其他目录中，我可以运行>>> import mongoengine
Traceback (most recent call last):

命令，但不能在我的项目目录中运行。例如，在import我得到：
/home/ubuntu/任何线索？
似乎有些混淆：使用>>> import mongoengine
>>>
安装pymongo和mongoengine：
pip答案 0 :(得分：0)
看起来pymongo或mongoengine不包含在您的默认python路径中。
尝试使用以下命令安装
pip install pymongo
pip install mongoengine
