termion does not support Windows. You can try using crossterm instead.

How can I install or implement this @kpreid ..

Now also I face this error

Whatever code you are trying to compile (aptos?) needs to be modified to use crossterm instead of termion. This is not a configuration change; it is modifying the code.

I had initially assumed you were writing code but now it sounds like you're compiling another crate that you didn't write.

You can find out where the termion dependency is by running cargo tree --invert termion, which will list dependency links starting from termion and ending at what you asked to compile. You should also check if the crate has a feature that can be disabled to avoid the dependency (this will require reading the involved Cargo.tomls).
