Jupyter notebook 在Julia中添加包的问题

首先，我是朱莉娅的新朋友，所以我还在习惯这种语言

我正在使用Jupyter，我正在尝试添加“特殊多项式”。 这是我一直得到的：

using Pkg
Pkg.add("SpecialPolynomials")

我尝试过解决我在网上遇到的类似问题的方法

我尝试删除特殊函数。 我试着用

]gc

+

输入

。

但是这些帖子中有很多都说要在git上引发一个问题，有人能看到是什么导致了这个问题吗？

只是没有一个受支持的intersect版本用于运行的

SpecialFunctions

/

SpecialPolynomials

和Julia 1.2。您应该更新到Julia 1.4，它（在撰写本文时）是当前受支持的版本。

谢谢！我手动卸载了1.2，然后从Julialang.org下载了1.4。我知道在未来，有没有更简单的方法从Jupyter做到这一点？做什么？下载新版本的Julia？不
