PermissionError: [Errno 13] Permission denied when running python-jl

Trying to get around the module import error discussed in #185 using Ubuntu on the Windows Linux Subsytem. However, when I run `python-jl` I'm getting the error:

```
Traceback (most recent call last):
File "/home/mr_bo/.local/bin/python-jl", line 11, in
sys.exit(main())
File "/home/mr_bo/.local/lib/python3.6/site-packages/julia/python_jl.py", line 117, in main
os.execvp(julia, [julia, "-e", script_jl, "--"] + unused_args)
File "/usr/lib/python3.6/os.py", line 559, in execvp
_execvpe(file, args)
File "/usr/lib/python3.6/os.py", line 603, in _execvpe
raise saved_exc.with_traceback(saved_tb)
File "/usr/lib/python3.6/os.py", line 594, in _execvpe
exec_func(fullname, *argrest)
PermissionError: [Errno 13] Permission denied
```

I'm really unclear about what's causing this. When I do `ls -ls ~/src/julia-1.0.2/bin/julia` I get `48 -rwxr-xr-x 1 mr_bo mr_bo 47296 Nov 8 16:16 /home/mr_bo/src/julia-1.0.2/bin/julia` which leads me to believe everything should be fine? Should I change the user and the group to something else?
