树梅派4B 安装 dash 成功。

Successfully installed dash-1.21.0 dash-core-components-1.17.1 dash-html-components-1.1.4 dash-table-4.12.0

• 代码如下：

# -*- coding: utf-8 -*-
import dash

• /thonny运行错误
  Traceback (most recent call last):
  File "/home/pi/Desktop/1222222.py", line 2, in
  import dash
  File "/usr/lib/python3/dist-packages/thonny/backend.py", line 305, in _custom_import
  module = self._original_import(*args, **kw)
  ModuleNotFoundError: No module named 'dash'

谢谢

dash版本问题，
安装这个版本的就好了
sudo pip install dash==0.29.0
