正開始使用api start app.py以下瓶Web服務器：通過MavProxy運行瓶（NoneType有沒有屬性startswith）
from flask import Flask
app = Flask(__name__)
給出了錯誤：
Exception in APIThread-0: 'NoneType' object has no attribute 'startswith'
Traceback (most recent call last):

時直接運行它工作正常，並CherryPy的作品當通過MavProxy運行時，所以我認爲它是路徑問題？這裏列出了Flask bootstrap的相同錯誤，但裸露的Flask不需要設置配置路徑。
