@qubitron
Are you testing this against the latest development version of the extension?
If not, please could you do so.

[qubitron]

Yes, I still have the issue against the latest development version of the extension (2018.11.0-alpha), on a mac:

mkdir newapp
cd newapp
code .

Create new file "hello.py"

Click the close button and then the interpreter shows:

Ok, I think I know what we need to do.
When VS Code loads and displays this message we need two options:

• [Change Default Python Interperter]
  • This will change the default python interpreter for the user in VS Code.
  • We basically update python.pythonPath in the user settings.json file
• [Select Python Interpeter]
  • Same as today, we update python.pythonPath in the workspace settings.json file

Next time VSC loads, user will not be prompted.

@qubitron
Please could you try the following:

• Open VSC, go into your user settings.json
• Update python.pythonPath to point to a valid python executable
• Reload VS Code (test this issue all over again), confirm this resolves the issue.

Changes:

• Remove dup ls message
• Auto select python environment before python validations
• Change label from 'available' to 'installed'
