Can't build react native app with expo

Question

Problem I made an app with react native (create react native app) and I am now trying to build it with expo. When I run "sudo exp build:android", I get two warnings (picture included) and then when the app starts building online it says that it had an error building the app. I am super confused, because I can run the app fine, it just won't build.

app.json

  {
       "expo": {
        "name": "Phoenix",
        "icon": "./CandidtwoImages/Phoenixlogo.png",
        "version": "0.1.0",
        "slug": "exp.io/@giise/candidtwo",
        "sdkVersion": "21.0.0",
        "ios": {
          "bundleIdentifier": "com.giise.phoenix"
        },
        "android": {
          "package": "com.giise.phoenix"
        }
       }
     }

嵌塞应该只是candidtwo -出版时蛞蝓是指你的URL的最后一部分，例如，与URL https://expo.io/@giise/candidtwo ， candidtwo是蛞蝓。
