Compilation 如何解决；LoadError:无法加载库编译错误“；可能来自PyPlot，在Juno命令提示符下？

当我尝试在Julia命令提示符下编译Julia文件时，如下所示：

julia> include("file.jl")

它向我显示了这个错误，我无法理解：

我如何解决这个问题？ 我注意到我已经安装了PyPlot：

julia> import Pkg; Pkg.add("PyPlot")
 Resolving package versions...
  Updating `~/.julia/environments/v1.0/Project.toml`
 [no changes]
  Updating `~/.julia/environments/v1.0/Manifest.toml`

我还注意到，我在使用Juno的第二个Julia命令窗口中遇到了这个错误，因为Juno的标准REPL正在运行一些其他代码。REPL中的其他代码也包括我的“错误”文件

file.jl、file2.jl和
file3.jl
，在那里运行得很好。
在我试图通过单击菜单栏
Juno->open External REPL打开第二个REPL后，问题自行解决了，当我试图通过单击菜单栏中的

，而不是我的初始
Juno->New Terminal->Current File's Folder
