Several on this site (including myself) use LTspice from Analog Devices which is one of the best free Spice simulators available.
But you will have to add the LM386 model (Goggle for model location and how to install it).

Welcome to AAC!

A spice model is posted in post #6 of this thread. LTspice is free, but the model should work with any spice simulator.

An LM386 is not an opamp, instead it is a power amp that has its inputs already biased and already has negative feedback.
Why do you need to simulate a simple LM386 power amplifier? For school work?
Power it, provide an input and its output will be less than 1 Watt in a speaker.
