React Navigation Error on npm install

Question

I'm trying to create a new react native app with react navigation.

I did the following:

1.) create-react-native-app myAppName

2.) cd myAppName/

3.) npm install --save react-navigation

4.) Expecting successful installation of react-navigation but instead i get:

Please Help, Cant npm start my React Native App.

Answer 1

It can be solved by running a npm install command again and reinstall the npm install --save react-navigation command.

Answer 2

I cant comment because I dont have the points, so heres a tentative answer with the info at the moment:

I had similar issue when running Expo on Windows. to solve I had to close XDE and reinstall.

if that's not enough, delete the "node_modules" folder and run "npm install".
