Question

使用api start app.py初始化以下Flask网络服务器：

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__)

    self.root_path = get_root_path(self.import_name)

    return os.path.dirname(os.path.abspath(filepath))
  File "/usr/lib/python2.7/posixpath.py", line 352, in abspath
    if not isabs(path):
  File "/usr/lib/python2.7/posixpath.py", line 61, in isabs
    return s.startswith('/')
AttributeError: 'NoneType' object has no attribute 'startswith'

直接运行时它工作正常，并且在通过MavProxy运行时Cherrypy工作，所以我认为它是路径问题？ Flask bootstrap此处列出了相同的错误，但裸Flask并不需要设置配置路径。

DKPY2.0（刚发布）没有MAVProxy依赖 - 脚本是“独立运行”。因此，只要flask在您的Python环境中，这应该“正常工作”

通过MavProxy运行Flask（NoneType没有属性startswith）
