I successfully installed Julia, atom, and Juno (including july-client, etc.)  
julia version 0.6.4  
It runs successfully directly from the command line.

But in the repl in atom, pressing enter causes the following error

```julia
Press Enter to start Julia. 
ERROR: LoadError: UndefVarError: @error not defined
Stacktrace:

 [4] _start() at .\client.jl:371
while loading C:\Users\ ***** \.atom\packages\julia-client\script\boot_repl.jl, in expression starting on line 1

```

I’ve tried to reinstall july-client, and Julia Path has been set.  
How to solve it? Thank you in advance.

Any reason why you choose such an old Julia version? To me it looks like the error would vanish if you switch to a newer (\>=1.0) version of Julia.

We’ve been trying to keep julia-client compatible with Julia 0.6, but recently merged a PR that broke that. Should be fixed again by [this](https://github.com/JunoLab/atom-julia-client/pull/654).

Because the code I want to run is based on Julia 0.6.I didn’t know if using the latest version would cause compatibility problems, so I chose this old version.  
I tried your suggestion, updating Julia version did solve the problem.Thanks a lot.
