The parameter `plotting_backend` must be either 'plotly', 'plotly-resampler' or 'matplotlib'.

这段代码是用于设置绘图后端的参数，可选参数包括'plotly'、'plotly-resampler'和'matplotlib'。其中，'plotly'和'plotly-resampler'是基于Plotly库的绘图后端，而'matplotlib'是基于Matplotlib库的绘图后端。该参数的作用是指定在使用MNE库进行脑电数据分析时所使用的绘图后端，以便在绘制结果时使用相应的库。在这段代码中，设置为'plotly-static'是无效的，因为该参数不是上述三个可选项之一。

这个错误通常是因为你的matplotlib库的backend没有正确设置，或者你的代码在非交互式环境中运行。你可以尝试在代码的开头添加下面这行代码来设置matplotlib的backend：

import matplotlib
matplotlib.use('TkAgg')

这里的'TkAgg'是一种常用的backend，你也可以根据自己的需要选择其他的backend。如果你已经设置了backend，但仍然出现这个错误，那么可能是你的代码在非交互式环境中运行。你可以尝试在交互式环境中运行代码，或者使用plt.savefig()函数将图像保存到文件中，而不是在窗口中显示。

这是一个 Python 的报错，提示 AttributeError: 'version_info' object has no attribute '__version__'，这可能是因为在导入 pyparsing 模块时出现了问题。建议检查 pyparsing 模块的版本是否正确，或者重新安装该模块。
