Are you talking about pichu or pikachu? You evolve pikachu by using a thunder stone on it and you evolve pichu by leveling it up while it has high friendship. To increase pichu's friendship give it a soothe bell to hold or feed it certain berries that increase friendship.
Pichu evolves into Pikachu when it has full Happiness. To increase its Happiness, you will need to level it up, feed it friendship boosting berries, walk around with it in your Party, take it to have a massage or haircut (depending on the version you are playing.), and/or give it stat boosting vitamins.
you have to make it happy you can do this by massages and giving it proteins you evolve pichu with happiness and freindship.you can also give him beris that make it frendlier
Pichu's FriendshipIf you have Pearl, Diamond, or Platinum, then check how much Pichu likes you using the 6th app. of your Poketch while having your Pichu in your party. If it has two big hearts above its head, then it will evolve as soon as you level it up, unless if you do something to lower its Friendship, liking giving it Herbs or letting it faint. In Ruby, Sapphire, Emerald, FireRed, or LeafGreen, you can't tell how much Pichu likes you, so you'll just have to keep on traveling and leveling it up. To make the whole thing easier, let Pichu hold a Soothe Bell as you travel and give it Pokeblocks or Poffins of its favorite flavor.
Give it ten of each stat level up potions like Iron and Protein and so on, then give it a massage in the house outside the Gym in Veilstone City, then he should love you enough to evolve
