Can you click the “Console” tab and show another screenshot?

Sorry, I meant the one in the upper right (in the dev tools).

Hm, that’s not terribly helpful… Can you try disabling the Powershell Wrapper option and switch the Console Mode to REPL-based, restart Atom, and try starting Julia again?

28

I have also tried with those options, but without results.
this is the current configuration:

Hmm… this is all very weird.

When you start with “Console Style” set to “REPL-based” and try to start Julia, do you see anything in the Julia REPL (Ctrl-J Ctrl-O to open that one)?

Julia could not be started.
We tried to launch Julia from:
C:\Users\user\AppData\Local\Julia-1.0.3\bin\julia.exe
This path can be changed in the settings.

That Cannot read property 'classList' of undefined error is unrelated, unfortunately.

  1. Can you try restarting Atom, and then open the REPL tab

    and then just press Enter? You might get a more informative error message there.
  2. If that doesn’t help, try renaming C:\Users\user\.atom to C:\Users\user\.atom.bak, reinstall Juno and try again.
32

I do not see, I do not have access to open the REPL tab!!!
Any combination of keys to launch REPL within Atom?

Even when I click on the STAR JULIA menu. The “REPL” window does not appear:

33

Yes, Ctrl-J Ctrl-O should do the trick. Or you use the toolbar button, or the Julia Client: Open Console command.

34

Complete the two steps in:
post #31
And I continue to present the problem:

I have installed Julia 0.7.0 and Julia 1.0.3.

Jilia%20070%20103
Jilia%20070%201031125×634 137 KB

When opening Atom for the first time after following the two steps of post # 31, Atom starts with Julia 0.7.0. But the error continues

36

Can you paste the following code into the Atom developer console and give me the output?

require('child_process').exec('C:\\Users\\user\\AppData\\Local\\Julia-1.0.3\\bin\\julia.exe --version', function(err, stdout, stderr) {
  if (err) {
    console.log(err)
  }
  let res = stdout.match(/(\d+)\.(\d+)\.(\d+)/)
  if (res) {
    console.log(res)
  } else {
    console.log('failed:')
    console.log(stdout)
  }
})

For me it looks like this:

Aha, that’s interesting (and weird).

The problem is that Atom (or rather, node) can’t find cmd – there are two possible causes for this:

  1. You don’t have C:\WINDOWS\system32 on your path – please check that in the Windows’ environment variables settings.
  2. Atom fails to pick up the correct environment variables. Try starting Atom by typing atom into a cmd/powershell session and try the code snippet again.
