我刚刚在Windows中安装了julia v1.0，并添加了PyPlot，然后尝试使用。 没有成功

我必须安装Python或其他外部文件或程序吗？ 情节也行不通！
答案 0 :(得分：1)
由于Julia v1.0是全新的，因此某些软件包尚不兼容。尽管已经进行了必要的更改，但是还没有被标记（发布），这很常见。要获取软件包的最新版本，可以执行add Packagename#master。如果是PyPlot，则需要LaTeXStrings的主版本，它是PyPlot的依赖项。以下应该起作用：
(v1.0) pkg> add LaTeXStrings#master
(v1.0) pkg> add PyPlot
