使用以下 Flask 网络服务器初始化api start app.py：

from flask import Flask
app = Flask(__name__)

给出错误：

Exception in APIThread-0: 'NoneType' object has no attribute 'startswith'
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/droneapi/module/api.py", line 333, in run
    self.fn()

    APIThread(self, lambda: execfile(args[1], g), args[1])

    app = Flask(__name__)

    return os.path.dirname(os.path.abspath(filepath))

    if not isabs(path):

    return s.startswith('/')
AttributeError: 'NoneType' object has no attribute 'startswith'

直接运行时工作正常，而 Cherrypy 通过 MavProxy 运行时工作正常，所以我认为这是路径问题？此处为Flask bootstrap列出了相同的错误，但裸 Flask 不需要设置配置路径。

DKPY2.0（刚刚发布）没有 MAVProxy 依赖项 - 脚本“独立”运行。因此，只要烧瓶在您的 Python 环境中，它就应该“正常工作”
