I have a similar issue. However I get this message for the Compat package, julia> Pkg.update() INFO: Updating METADATA… INFO: Computing changes… ERROR: resolve is unable to satisfy package requirements.

However, this only means that package Compat is involved in an unsatisfiable or difficult dependency relation, and the root of the problem may be elsewhere.

Not sure how functional the install is at this polnt.

I got around the problem. What I did was to install the command line Julia, and then installed atom independently. Then I installed the Julia packages inside atom. Finally, I linked atom to the binaries of the command line Julia. It’s working fine now.

The command line julia is presumably the one you can download from Julia’s main web page. However is that julia actually 0.6.2.2? The reason I ask is that another package, DifferentialEquations, I think seems to require the later julia. Not sure how you can detect the minor version numbers within julia, since both 0.6.2.1 and 0.6.2.2 show the version as 0.6.2. Maybe versioninfo() gives more information. What this means is that you are not running JuliaPro, if that makes any difference, and it means that JuliaPro 0.6.2.2 appears to have problems for some users.

[image] mattcbro: The command line julia is presumably the one you can download from Julia’s main web page. However is that julia actually 0.6.2.2? AFAIK the binaries just use major.minor.patch semantic versioning, so the current stable is v0.6.2. The additional .2 is a JuliaPro thing.

You are right. The command line Julia is version 0.6.2. However, I have added the package DifferentialEquations in the same version, and it works fine. When you start Julia, it’s gives the version number in the “preamble.”

Can you describe (or provide a link) the process of linking atom to the binaries of Julia Command line?

The step-by-step process is given in the following link: http://docs.junolab.org/latest/man/installation.html After you set up Julia in Atom, go to “Julia” tab, then click “settings”. Inside the settings, you will notice the entry “Julia Path.” There, all you have to do is give the path to the “bin” folder that you get when you install the command line Julia on your system. Hope that helps.

Thanks Harsha, this worked for me. Now if I could just get the MKL version to work. It seems that it’s using my system python instead of the supplied python and creating some kind of conflict with the Blas libraries.
