react-native: Command `run-android` unrecognized. Maybe caused by npm install

Question

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.

• Step 2 - Run the "run-android" command (This works).

• Step 3 - Install "react-native-navigation" into project.

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)

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

Answer 1

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.
