Installing julia on Ubuntu 16.04 VM

General Usage

Hello

I am having trouble to install/update any package on julia 0.6
for example Pkg.update() leads to the following error

julia> Pkg.update()
INFO: Initializing package repository /root/.julia/v0.6
ERROR: ReadOnlyMemoryError()
 in cd(::Base.Pkg.Dir.##4#6{String,String}, ::String) at ./file.jl:65
 in init(::String, ::String) at ./pkg/dir.jl:47
 in #cd#1(::Array{Any,1}, ::Function, ::Function, ::String, ::Vararg{Any,N}) at ./pkg/dir.jl:28
 in cd(::Function, ::String, ::Vararg{Any,N}) at ./pkg/dir.jl:25
 in update() at ./pkg/pkg.jl:210

Any ideas how to solve this ?

I am using ubuntu 16.04 using a virtual machine (Oracle VM) on windows 7

Thanks a lot

The local package repository .julia/ should be in your home directory. Are you running as root? What is the output of homedir()? You should also probably initialize the repository with Pkg.init() first.

Thanks for your answer:
the homedir() command outputs

julia> homedir()
“/root”

here is the output for Pkg.init

julia> Pkg.init()
INFO: Initializing package repository /root/.julia/v0.6
ERROR: ReadOnlyMemoryError()
in cd(::Base.Pkg.Dir.##4#6{String,String}, ::String) at ./file.jl:65
in init(::String, ::String) at ./pkg/dir.jl:47
in init() at ./pkg/pkg.jl:70

I guess julia is installed in the wrong place …
Do you know how I can fix this ?

Thanks a lot

I usually don’t run programs as root and I would not know how to solve it. Can you log in or create a normal user instead?

Then, as a normal user, you could download the generic Linux binaries, put them in a local directory and it should work. Also, unless you are an experienced user, you should use the stable release v0.5.1.

I downloaded the binaries and extracted them in my local directory, however I don’t know what to do next …
I tried to look for some installation or to launch directly julia but not working …

Could launch julia using ./julia in the bin folder, however I have the same problem

julia> Pkg.init()
INFO: Initializing package repository /home/plp/.julia/v0.5
ERROR: ReadOnlyMemoryError()
in cd(::Base.Pkg.Dir.##4#6{String,String}, ::String) at ./file.jl:55
in init(::String, ::String) at ./pkg/dir.jl:47
in init() at ./pkg/pkg.jl:70

I have no idea. Can you cd into ~.julia/v0.5?
