Julia 1.0.0 : Error trying to add PyPlot package

Question

不确定如何响应尝试添加 PyPlot 时出现的以下错误消息:

julia> # Fresh 1.0.0 REPL

julia> versioninfo()

 └─restricted by julia compatibility requirements to versions: uninstalled — no versions left

有什么建议吗？

编辑

根据 Bogumił Kamiński 非常有帮助的答案，我执行了以下操作，并且在重新启动 REPL 后它起作用了。这是基于响应错误消息的简短摘要:

(v1.0) pkg> rm Benchmark

(v1.0) pkg> add PyPlot

(v1.0) pkg> build PyCall

# Restart REPL
julia> using PyPlot

julia> plot([1, 2, 3, 4, 5], [3, 5, 10, 4, 2])
1-element Array{PyCall.PyObject,1}:
 PyObject <matplotlib.lines.Line2D object at 0x0000000034CDEE48>

julia> # It works!

Answer 1

参见https://discourse.julialang.org/t/package-compatibility-caps/15301 .

最有可能的问题是您安装了未维护的包 Benchmark。

在尝试安装 PyPlot 之前，通过以下方式卸载软件包 Benchmark:(v1.0) pkg> rm Benchmark。
