Recently I started getting this issue, when I install a react-native package (eg: react-navigation) into my project, a whole bunch of packages are been removed (including react, react-native i think).

And then when i try to run command "run-android", it says it doesn't recognize.

I recently updated to the latest npm and react-native-cli. Is it something wrong with "npm install"? or react-native?

node version: 8.1.2 <br/>
react-native-cli: 2.0.1 <br/>
react-native: 0.45.1 <br/>
react-navigation: 1.0.0-beta.11

Below are the steps to re-create:

  • Step 1 - Create project. enter image description here

  • Step 2 - Run the "run-android" command (This works). enter image description here

  • Step 3 - Install "react-native-navigation" into project. enter image description here

Notice in the image above. Seems like all the other packages are removed from the project.<br/><br/>
  • Step 4 - Try running "run-android" command again. (will fail, but used to work before) enter image description here

Any idea on what the issue is and any way to solve it?

Found the solution here.

At first running npm install didn't work, but then, deleting the package-lock.json file and running npm install did the job.

After that I installed react-navigation package seperately and it worked fine.
