I have the 7zip file manager installed, but how do I solve this?

[twavv]

Did you build Julia from source, or download a pre-compiled executable?

[Datseris]

I downloaded a pre-compiled executable. Everything stable version 1.3.1

[twavv]

This is probably caused by #229, though that was supposed to fix these issues.

Can you report the output of readdir(joinpath(Sys.BINDIR, Base.LIBEXECDIR))?

For me (on a Mac):

julia> readdir(joinpath(Sys.BINDIR, Base.LIBEXECDIR))
1-element Array{String,1}:
 "7z"

[Datseris]

For me I get

julia> readdir(joinpath(Sys.BINDIR, Base.LIBEXECDIR))
2-element Array{String,1}:
 "7z.dll"
 "7z.exe"

[twavv]

Curious. I'm not sure how to debug this any further.

The message

│ IOError: could not spawn `'C:\Users\datse\AppData\Local\Julia-1.3.1\bin\7z.exe' x electron-v4.0.4-win32-x64.zip -y -oatom`: no such file or directory (ENOENT)

is pretty informative: it failed to spawn 7z.exe, which is weird since it looks like it exists.

What happens if you do this?

run(`C:\Users\datse\AppData\Local\Julia-1.3.1\bin\7z.exe`)

It should error (because we're not giving it the correct arguments), but it shouldn't be an ENOENT (which signifies that the executable doesn't actually exist).

Hm, this is sad. It looks like its a problem on my end?

But I don't know how to solve it though.

[twavv]

Oh, sorry, I forgot to escape backslashes (see the C:UsersdatseAppDataLocalJulia-1.3.1bin7z.exe bit).

Try

run(`C:\\Users\\datse\\AppData\\Local\\Julia-1.3.1\\bin\\7z.exe`)

[Datseris]

I get

[twavv]

Oh, I think I see the issue. It should be Julia-1.3.1\libexec\7z.exe, but instead libexec is just bin.

Are you using the latest version of Blink (0.12.1)? That's where we made the change to use BinDeps instead of using the old logic (which I think had that bug, since the 7z exe was moved in Julia 1.3).

[Datseris]

Yes I am using latest stable version.

[twavv]

What's the output of

using Pkg
Pkg.add("BinDeps")
using BinDeps
@show BinDeps.unpack_cmd(file, "atom", ".zip", nothing)

[Datseris]

what's file in your code?
