I will check this, been off coding for two months.

I was getting the same error. You fixed the source of the error on May 28, 2019 (9e9efaa), but the latest release on PyPi is from 2018. The error goes away if I change the offending line. I ended up just git cloning the latest commit and installing it from the local folder.

Same here. I get the error with the PyPI version of PyInquirer under Python 3.7.

Instead of @nesadi approach, you can also just pass a Validator into the 'validate' key...

from PyInquirer import prompt, Validator, ValidationError
...
class ValidateEditor(Validator):
    def validate(self, document):
        if document.text and len(document.text.split('\n')) <= 1:
            raise ValidationError(
                message='Must be at least 1 line', cursor_position=len(document.text))
...
def askPaste():
    questions = [
        {
            'name': 'content',
            'type': 'editor',
            'message': 'Opening editor',
            # lambda text: len(text.split('\n')) >= 1 or 'Must be at least 1 line',
            'validate': ValidateEditor,
            'eargs': {
                'editor': 'default',
                'ext': '.tmp'
            },


        },
    ]
    return prompt(questions)

@CITGuru Could we please get a new release to PyPi that includes 9e9efaa ? Many uses of the editor prompt are broken otherwise. Thanks!
