Julia Interact.jl错误：未定义WebIOServer

在Juno中使用Interact.jl@operate宏时，我遇到此错误：

UndefVarError: WebIOServer not defined

• 一段代码（函数generatePlot先前定义用于生成Makie图）：

环境：

你有什么想法吗

@manipulate for variable = Dict(string(vars[i])=>vars[i] for i=1:16),
                labl = Dict(string(label[i])=>label[i] for i=1:length(label))
                generatePlot(variable, labl)
end
