AttributeError: module 'inspect' has no attribute 'getargspec'. Did you mean: 'getargs'?

See original GitHub issue

I’m having an issue running invoke (latest) in Python 3.11-dev (3.11.0a3). For this tasks file, this is the trace I get:

AttributeError: module 'inspect' has no attribute 'getargspec'. Did you mean: 'getargs'?

It works perfectly fine for any other Python version I tried (3.7, 3.8, 3.9, 3.10, PyPy3.7, PyPy3.8, Stackless3.7, Stackless3.8).

The module inspect does indeed not have said attribute, and I see that there’s a potential replacement done in invoke.vendor.decorator for some reason.

Until an update is released this can be worked around temporarily with a hack to monkey patch the inspect module in your tasks.py file. Here is an example working for me on Python 3.11:


import inspect

if not hasattr(inspect, 'getargspec'):
    inspect.getargspec = inspect.getfullargspec

from invoke import task

@task
def say_hello(c):
    print("Hello, World!")
