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?

HerAdri · January 10, 2019, 9:19am

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

pfitzseb · January 10, 2019, 9:22am

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)?

HerAdri · January 10, 2019, 9:27am

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.

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

image961×302 3.91 KB

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

HerAdri · January 10, 2019, 9:53am

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:

pfitzseb · January 10, 2019, 10:05am

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

HerAdri · January 10, 2019, 10:34am

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

HerAdri · January 10, 2019, 11:06am

I have installed Julia 0.7.0 and Julia 1.0.3.

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

pfitzseb · January 10, 2019, 11:28am

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:

HerAdri · January 10, 2019, 11:31am

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)
  }
})

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:

You don’t have C:\WINDOWS\system32 on your path – please check that in the Windows’ environment variables settings.
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.
