Installed JuliaPro-0.6.1.1 on Ubuntu-16.04, in a parallel directory to base Julia-0.6.

Julia console in the JuliaPro installation of Atom always lead to a fatal error, which traced to this:

```julia
JuliaPro julia> using Atom
ERROR: SystemError: opening file /home/myName/.juliapro-0.6.1.1/lib/v0.6/Atom.ji: Permission denied
Stacktrace:
 [1] #systemerror#44 at ./error.jl:64 [inlined]
 [2] systemerror(::String, ::Bool) at ./error.jl:64
 [3] open(::String, ::Bool, ::Bool, ::Bool, ::Bool, ::Bool) at ./iostream.jl:104

 [7] _require(::Symbol) at ./loading.jl:441
 [8] require(::Symbol) at ./loading.jl:405

```

JuliaPro doesn’t have the proper permissions to open `Atom.ji`. Which seemed strange. So, comparing the installation directories of base Julia and JuliaPro:

```julia
$ ls -l ~/.julia/lib/v0.6/ | grep Atom.ji
-rw------- 1 myName myName 137120 Dec 27 20:45 Atom.ji

```

```julia
$ ls -l ~/.juliapro-0.6.1.1/lib/v0.6/ | grep Atom.ji
-rw------- 1 root root 142271 Dec 27 20:37 Atom.ji

```

JuliaPro installed all the `.ji` files as root. To test further, I deleted all the JuliaPro directories, including `~/.juliapro-0.6.1.1`, and reinstalled JuliaPro from the shell script, _without_ super user permissions.

Result: All the JuliaPro `.ji` files were still installed as root.

Solution: change the ownership. From bash terminal:

```julia
sudo chown myName ~/.juliapro-0.6.1.1/lib/v0.6/*.ji

```

Now the JuliaPro version of Atom/Juno works fine. Hope this helps other users.

**tl;dr**

Changed the ownership of all the `.ji` files to my username.

Thanks for posting this. This issue still persists. What would be the windows equivalent of this solution?

I’m on Julia 1.7

Could you please start a new issue with your exact error output? The original post is from five years ago and the current issue is likely unrelated.
