First update your dependencies version from below dependencies then add your additional required dependencies in that from yours:
{
"name": "nativebasedemo",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start",
"test": "jest",
"clean": "rm -rf $TMPDIR/react-* && watchman watch-del-all && npm cache clean --force",
"newclear": "rm -rf $TMPDIR/react-* && watchman watch-del-all && rm -rf ios/build && rm -rf node_modules/ && npm cache clean --force && npm i",
"test:watch": "jest --watch",
"lint": "eslint ./App",
"lintdiff": "git diff --name-only --cached --relative | grep '\\.js$' | xargs standard | snazzy",
"fixcode": "eslint --fix ./App",
"git-hook": "npm run lint -s && npm run test -s",
"rm-node": "rm -rf node_modules && npm install"
},
"dependencies": {
"lodash": "^4.17.10",

Answer 2

I had a similar issue, with both react and react-native.
Ended up locking down native-base version to 2.6.1.
This way, native-base doesn't ask for higher versions, which sdk-28.0.0.tar.gz doesn't have.
