I use RVM to change Ruby versions in my Mac-based development environment.

Inside Visual Studio Code, when I open a regular Terminal tab, I'm dropped into a bash login shell with the -l option, per the standard default configuration, and as documented here:

// VSCode default settings

{

  "terminal.integrated.shell.osx": "/bin/bash",

  "terminal.integrated.shellArgs.osx": [

    "-l"

  ]

}

The RVM command executed manually from VSCode Terminal gives me the expected ruby version for this project by default.

$ rvm list

  ruby-2.0.0-p648 [ x86_64 ]

  ruby-2.1.10 [ x86_64 ]

  ruby-2.1.5 [ x86_64 ]

  ruby-2.2.10 [ x86_64 ]

  ruby-2.2.5 [ x86_64 ]

  ruby-2.3.0 [ x86_64 ]

* ruby-2.3.1 [ x86_64 ]

=> ruby-2.3.7 [ x86_64 ]



# => - current

# =* - current && default

#  * - default

However, when I setup a .vscode/tasks.json file to execute that same command the Ruby version is NOT the correct version, but the default one on the system. Futhermore, I'm unable to actually use rvm use to switch versions (see error message below)

{

  // See https://go.microsoft.com/fwlink/?LinkId=733558

  // for the documentation about the tasks.json format

  "version": "2.0.0",

  "tasks": [

    {

      "label": "Check for RVM",

      "type": "shell",

      "command": "rvm list && rvm use 2.3.7",

      "group": {

        "kind": "test",

        "isDefault": true

      }

    }

  }

}

Output of task execution, with error message about not having a correct login shell.

RVM is not a function, selecting rubies with 'rvm use ...' will not work.



You need to change your terminal emulator preferences to allow login shell.

Sometimes it is required to use `/bin/bash --login` as the command.

Please visit https://rvm.io/integration/gnome-terminal/ for an example.





Terminal will be reused by tasks, press any key to close it.

I've even tried specifically adding the -l bash command option as an argument in the Task's configuration, but this does not work.

  "options": {

    "shell": {

      "args": "-l"

    }

  }

My understanding, after reading through this issue is that the Terminal shell config and the Task shell config is one and the same, so is there some other underlying inconsistency between Terminal shell and Task shell that I'm missing? If not, then what is it about RVM that prevents it from working inside a Task shell?
