Set the oven to 375°F (190°C).
In a large bowl, combine mashed sweet potatoes, sugar, salt, cinnamon, nutmeg, ginger, and cloves. Mix until smooth.
Stir in beaten eggs, evaporated milk, and vanilla extract. Mix just until blended.
Pour the filling into the unbaked pie crust, smoothing the top evenly.
Place in the preheated oven and bake for 50–60 minutes, or until a knife inserted near the center comes out clean.
Transfer to a wire rack and let cool completely before slicing. The filling will continue to firm as it cools.
