Julia：如何更新到软件包的最新版本（即Flux）

Question

我有Julia 1.1

我想更新到软件包的最新版本，在这种情况下，根据Flux 8.3.0，将为documentetiation of Flux.jl

输入时]

Pkg.status("Flux")
我知道

Status `~/.julia/environments/v1.1/Project.toml`
[587475ba] Flux v0.6.10
我也都尝试过：

Pkg.add("Flux")
Pkg.update("Flux")
但不会更改版本

编辑

在BogumiłKamiński发表评论后，我尝试了以下命令

Pkg.update()
给我

我有Julia 1.1，我想更新到软件包的最新版本，在这种情况下，当我键入Pkg.status（“ Flux”）时，根据Flux.jl的说明，Flux 8.3.0会得到Status`〜/。 julia / ...

[正如BogumiłKamiński所评论的，删除.julia / registries / General目录并运行Pkg.update（）起作用。！
