如何使用julia'；s PackageCompiler为PlotStats构建快速启动环境？

我想使用“DataFrames，CSV，StatsPlots”软件包，在重新启动计算机后无需等待时间，我正在尝试使用PackageCompiler，但自述文件或帮助很难理解

using using PackageCompiler
syso, sys = compile_incremental(:DataFrames,:CSV,:StatsPlots)

嗯，我害怕破坏系统映像，所以，首先，我不使用'force=true'选项。它显示错误消息：

通过PackageCompilerX，它似乎是可行的。首先，软件包的版本非常敏感，它需要正确的版本才能让一切正常工作

下面是我针对julia 1.3.1的两个测试环境

• debian:apt-t不稳定安装julia-libjulia-dev
• archlinux:pacman-sJulia

检查Julia的版本（PackageCompilerX仅适用于1.3.1之后的版本）

添加PackageCompilerX和要打印到存储库的所有包

pkg> add https://github.com/KristofferC/PackageCompilerX.jl
pkg> status
Status `~/.julia/environments/v1.3/Project.toml`
...

将系统的Project.toml复制到当前目录以自定义您的开发环境，使用编辑器（此处

vim

）删除一些无法编译或不需要的包

shell> rm Project.toml
shell> cp ~/.julia/environments/v1.3/Project.toml .
shell> vim Project.toml

激活本地包环境

julia> using PackageCompilerX
pkg> activate .
pkg> status  # double check all package which you want have installed
    Status `~/prj/julia/Project.toml`
  [336ed68f] CSV v0.5.22
  [a93c6f00] DataFrames v0.20.0
  ...

在julia提示符中自动生成sybmol数组

s=split(read("Project.toml", String),"\n")
pkgs=Symbol[]
for i in s
  if (length(i) > 0) && !(i[1] in ['[','#'])
    push!(pkgs, Symbol(split(i," ")[1]))
  end
end

展示包装

julia> pkgs
10-element Array{Symbol,1}:
 :CSV
 :DataFrames
 ...

编译它并输出到“dev.so”

退出julia，然后按重新启动julia

julia -J dev.so

对这两种发射方法和结果进行基准测试：

time julia -q -e 'using Plots,UnicodePlots; unicodeplots(); display(plot(sin))'
# result: 35.175s
time julia -J dev.so -q -e 'using Plots,UnicodePlots; unicodeplots(); display(plot(sin))'
# result: 15.2365s

julia -J dev.so

time julia -q -e 'using Plots,UnicodePlots; unicodeplots(); display(plot(sin))'
# result: 35.175s
time julia -J dev.so -q -e 'using Plots,UnicodePlots; unicodeplots(); display(plot(sin))'
# result: 15.2365s
