julia - 如何在 Julia 1.0 中离线安装 julia 包？

Question

我有自己的 julia 包，在 Julia 0.6 上运行良好。当我尝试升级到 julia 1.0 时，我发现在 Julia 1.0 中添加我自己的包更加困难。我不能把它放在 pkg.dir() 下。在我的情况下，包只是我本地磁盘上的几个文件，除了 julia 本身之外不依赖任何其他东西。我可以在新的包管理器中将它与“生成”和“激活”一起使用，但是，在重新启动 REPL 后，我必须重做“生成”和“激活”。有没有办法永久安装软件包？谢谢!

我尝试将自己的包文件放在 JULIA_DEPOT_PATH/MyPackageName/src 下。我也尝试将文件放在 MyPackageName/random-five-char/src/下。两者都不起作用。

Answer 1

however, after restart the REPL, I have to redo the 'generate' and 'activate'.

事实上，你不必这样做。你试了吗 activate /your/package/path/package_name而不是 activate package_name ?

(v1.0) pkg> generate ./MyPackgePath/MyPackageName
Generating project MyPackageName:
    ./MyPackgePath/MyPackageName/Project.toml
    ./MyPackgePath/MyPackageName/src/MyPackageName.jl

julia> using MyPackageName  # it won't work because it's not in the default environment

Is there a way to install the package perpetually?

IIUC，您想要的是在默认环境中安装软件包(例如 (1.0) )。最简单的方法是 dev /your/package/path/package_name .
