Bokeh新版本与pytrendline不兼容，旧版本安装失败求助

运行代码时的属性错误 #

尝试用pytrendline在图表上绘制趋势线，运行代码时触发以下错误：

AttributeError: unexpected attribute 'render_mode' to Label, similar attributes are renderers

推测是Bokeh新版本与pytrendline库不兼容导致。注意到pytrendline的requirements.txt中要求bokeh>=2.0.2，但当前高版本Bokeh运行时却报错。

安装低版本Bokeh时的元数据生成错误 #

尝试安装低版本Bokeh来解决兼容性问题，却遇到如下错误：

疑问 #

• 是否只能通过conda安装低版本Python来解决问题？
• 为什么pytrendline要求bokeh>=2.0.2，但高版本Bokeh反而无法正常运行？
