尝试在 Julia 上安装自定义包时出错

Question

我正在尝试使用命令 Pkg.add(PackageSpec(path = "")) 在 Julia 中安装自定义包，该命令位于我的本地目录中。我使用本地路径中的 Julia documentation. But every time when I am trying to install my custom package using PackageSpec 创建了我的包，它抛出了一个错误。以下错误是 -

Cloning git-repo `D:\df_sql\src\df_sql.jl`

我的项目结构是-

我正在使用 Julia 版本 1.6.0 知道如何解决这个问题！！！

我相信您需要在该文件夹中有一个初始化的 Git 存储库才能将其添加为一个包。以下是我为获取可以在 Julia 本地安装的软件包所做的步骤：

设置

using Pkg
Pkg.generate("MyPackage")
open("MyPackage/src/MyPackage.jl","w") do f
    println(f, """
module MyPackage
foo(what) = println("Hello " * what)
export foo
end
    """)
end

按;进入命令行shell模式：

shell> cd MyPackage

shell> git init

shell> git add *

shell> git commit -m init

shell> cd ..

现在你可以安装包了

julia> Pkg.add(path="MyPackage")
     Cloning git-repo `C:\temp\MyP\MyPackage`
    Updating git-repo `C:\temp\MyP\MyPackage`
    Updating registry at `C:\JuliaPkg\Julia-1.7.0\registries\General.toml`
   Resolving package versions...
    Updating `C:\JuliaPkg\Julia-1.7.0\environments\v1.7\Project.toml`
  [7e0d665f] + MyPackage v0.1.0 `..\..\..\..\temp\MyP\MyPackage#master`
    Updating `C:\JuliaPkg\Julia-1.7.0\environments\v1.7\Manifest.toml`
  [7e0d665f] + MyPackage v0.1.0 `..\..\..\..\temp\MyP\MyPackage#master`
Precompiling project...
  1 dependency successfully precompiled in 5 seconds (316 already precompiled)

包已安装，可以使用

julia> using MyPackage

julia> foo("world")
Hello world

备注

您可以通过使用 Pkg.develop 来避免初始化 Git 存储库，在上述说明的第 1 步之后您可以执行以下操作：

julia> Pkg.develop(path="MyPackage")
   Resolving package versions...
    Updating `C:\JuliaPkg\Julia-1.7.0\environments\v1.7\Project.toml`
  [7e0d665f] + MyPackage v0.1.0 `..\..\..\..\temp\MyP\MyPackage`
    Updating `C:\JuliaPkg\Julia-1.7.0\environments\v1.7\Manifest.toml`
  [7e0d665f] + MyPackage v0.1.0 `..\..\..\..\temp\MyP\MyPackage`

julia> using MyPackage

julia> foo("world")
Hello world
