这个示例也是报同样的错

会不会是你的GR后端没开啊,试试

using GR
gr()

应该和gr没关系
我是参考的这个
https://juliadata.github.io/JuliaDB.jl/stable/plotting/#StatsPlots-1

JuliaDB has all access to all the power and flexibility of Plots via StatsPlots and the @df macro.

其实就是用了 Plots.jl ,先确保你有一个能用的后端。

StatsPlots已经安装好了的,
看提示是没找到调用的函数

环境没有安装好,全部卸载,重来就好了
