server - 在 Julia 上全局安装一个包

Question

我在一台机器上安装了一个新的 Julia，我想将它用作实验室中各种人员的数字处理服务器。似乎有一个叫做 jupyterhub 的好包，它使 Jupyter Notebook 界面同时可供各种客户端使用。我无法再次找到的网页开始建议诸如“首先全局安装 IJulia，然后安装 JupyterHub...”

我似乎找不到一种在全局安装 ONE 软件包的好方法。

更新

在 Julia-v0.7+ 中，我们需要使用 JULIA_DEPOT_PATH而不是 JULIA_PKGDIR和 LOAD_PATH看起来像这样:

julia> LOAD_PATH
3-element Array{Any,1}:
 Base.CurrentEnv()                                                                                                                     
 Any[Base.NamedEnv("v0.7.0"), Base.NamedEnv("v0.7"), Base.NamedEnv("v0"), Base.NamedEnv("default"), Base.NamedEnv("v0.7", create=true)]
 "/Users/gnimuc/Codes/julia/usr/share/julia/stdlib/v0.7"

"first install IJulia globally, then install JupyterHub..."

不知道是不是真的，按照下面的步骤，你就可以安装 IJulia安装后 Jupyterhub .

为每个用户在系统范围/全局安装软件包

这个问题已经回答了 here斯蒂芬·卡尔平斯基 (Stefan Karpinski)所以我们需要的只是用这个方法安装 IJulia.jl包裹。

There's a Julia variable called LOAD_PATH that is arranged to point at two system directories under your julia installation. E.g.:

julia> LOAD_PATH
2-element Array{Union(ASCIIString,UTF8String),1}:
 "/opt/julia-0.3.3/usr/local/share/julia/site/v0.3"
 "/opt/julia-0.3.3/usr/share/julia/site/v0.3"

If you install packages under either of those directories, then everyone using that Julia will see them. One way to do this is to run julia as a user who can write to those directories after doing export JULIA_PKGDIR=/opt/julia-0.3.3/usr/share/julia/site in the shell. That way Julia will use that as it's package directory and normal package commands will allow you to install packages for everyone....

让 IJulia 与 Jupyterhub 一起工作

为了使 IJulia和 Jupyterhub为所有用户相互协作，您应该复制文件夹 your/user/.local/share/jupyter/kernels/julia/至 /usr/local/share/jupyter/kernels/ .我写下我在测试中使用的一些步骤 Dockerfile .代码很丑，但它有效。

步骤:(成功安装Jupyterhub后)

请注意，您应该以 root 身份执行以下步骤，我假设您的 julia 已全局安装在 /opt/julia_0.4.0/ .

创建我们的全局包目录并设置 JULIA_PKGDIR :

mkdir /opt/global-packages
echo 'push!(LOAD_PATH, "/opt/global-packages/.julia/v0.4/")' >> /opt/julia_0.4.0/etc/julia/juliarc.jl
export JULIA_PKGDIR=/opt/global-packages/.julia/

使用包管理器安装“IJulia”:

julia -e 'Pkg.init()'
julia -e 'Pkg.add("IJulia")'

复制 kernelspec转至 /usr/local/share/jupyter/kernels/ Jupyterhub 添加的任何新用户都可以使用它:

jupyter kernelspec list
cd /usr/local/share/ && mkdir -p jupyter/kernels/
cp -r /home/your-user-name/.local/share/jupyter/kernels/julia-0.4-your-julia-version /usr/local/share/jupyter/kernels/
