python - Pyforms AttributeError:“模块”对象没有属性“start_app”

在我的覆盆子Pi 3上安装pyforms之后，我尝试运行在readthedocs上找到的示例，但是应用程序抛出了一个AttributeError（我同时尝试了python2和python3）
Python代码

import pyforms
from   pyforms          import BaseWidget
from   pyforms.Controls import ControlText
from   pyforms.Controls import ControlButton

class SimpleExample1(BaseWidget):

    def __init__(self):
        super(SimpleExample1,self).__init__('Simple example 1')

        #Definition of the forms fields
        self._firstname     = ControlText('First name', 'Default value')
        self._middlename    = ControlText('Middle name')
        self._lastname      = ControlText('Lastname name')
        self._fullname      = ControlText('Full name')
        self._button        = ControlButton('Press this button')


#Execute the application
if __name__ == "__main__":   pyforms.start_app( SimpleExample1 )

错误：

Traceback (most recent call last):
  File "PiControl.py", line 20, in <module>
    if __name__ == "__main__":   pyforms.start_app( SimpleExample1 )
AttributeError: ‘module’ object has no attribute ‘start_app’

编辑：
我试图用

from pyforms.gui.standaloneManager import start_app

但我得到另一个start_app：

Traceback (most recent call last):
  File "PiControl.py", line 4, in <module>
    from   pyforms.gui.standaloneManager import start_app
ImportError: cannot import name 'start_app'

最佳答案

这是非常奇怪的行为，可能意味着您的安装已损坏。尝试从回购安装最新版本：

pip install -U git+https://github.com/UmSenhorQualquer/pyforms.git
pip install -U git+https://github.com/UmSenhorQualquer/pysettings.git
pip install -U git+https://bitbucket.org/fchampalimaud/logging-bootstrap.git
