Question

我无法在ESP32 Wroom板上运行状态机库“ upysm”，它是pysm的Micropython调整版本。

该板已连接到WLAN，并且我发出了以下命令，如文档中所示：

import upip
upip.install('upysm')

lib似乎已加载（我在/ lib文件夹中看到文件）并已安装：

  File "/lib/pysm/pysm.py", line 93, in <module>

我要关注的最后一行。

现在我正尝试通过以下方式在main.py中使用该库：

from pysm import State, StateMachine, Event
on = State('on')

结果再次是错误：

Traceback (most recent call last):
  File "main.py", line 13, in <module>
  File "/lib/pysm/__init__.py", line 2, in <module>
  File "/lib/pysm/pysm.py", line 93, in <module>
AttributeError: 'module' object has no attribute 'StreamHandler'

Type "help()" for more information.
>>> Running main.py

>>> 
>>> Traceback (most recent call last):
  File "<stdin>", line 15, in <module>
ImportError: no module named 'pysm.State'

看来我已经接近解决方案，但显然不够接近。

使其运行的最佳方法是什么？

我从头开始刷新，使用了官方文档中的示例代码

无法在ESP32上运行pysm-'模块'对象没有属性'StreamHandler'错误
