react-native run-android is unrecognized

Question

I've installed react-native-cli globally:

npm install -g react-native-cli

Then run:

react-native init AwesomeProject
cd AwesomeProject

I got the following structure:

-- AwesomeProject   
---- node_modules      
------ react-native

When I run react-native run-android I get an error:
Command run-android unrecognized. Did you mean to run this inside a react-native project?

When I run react-native start I get the same.

react-native -v
prints:
react-native-cli: 0.2.0
react-native: n/a - not inside a React Native project directory

What I'm doing wrong?

cd into AwesomeProject then run react-native --version – CrackerKSR Feb 16 '22 at 10:32 — CrackerKSR, Feb 16 '22 at 10:32

What caused this for me was running npm install --save [package] when actually the system has previously been using yarn instead of npm.

To solve this I just deleted the node_modules folder and ran: yarn install and after that react-native run-ios (or android) works fine.

(This is a duplicate of React Native: Command `run-ios` unrecognized)

The problem was that I terminated init command because it looked like hanged without errors (even 24 hours later). To fix this I updated nodejs and npm to newer versions. Once I have done it react-native init was executed properly and there is no more problem with react-native run-android.

This can be caused by a couple of issues.

!!! Before trying each solution remember to open a new terminal since you might have old paths sources from your .bashrc file. !!!

You did not install the contents of the project. In order to solve this you have to install the node_modules by typing:

npm install or yarn install
You are coming back to a previously installed project after doing some funny things with your react-native installation and global configurations. (Upgrading the library, upgrading node doing something with globally installed node_modules).

You should clean all your caches and project modules

Here you can find a command to do all these things in one line (remember to replace npm with yarn accordingly): https://gist.github.com/jarretmoses/c2e4786fd342b3444f3bc6beff32098d

Your global installation of react-native or react-native-cli is broken. In this case simply reinstall your libraries globally.

npm: npm install -g react-native && npm install -g @react-native-community/cli

yarn: yarn global add react-native && yarn global add @react-native-community/cli

I think the command you are looking for is react-native run-android.

cd into your project and run this command where all you js files are present and not in the android folder.

It will run a package manager, do not close that. Also you need to have an emulator or a device connected to your computer with usb debugging enabled.

Hope the answer helped

react-native run-android - that is the command that I have used. And I did it from within AwesomeProject directory. – Sergey Onishchenko Jun 03 '16 at 11:12
hmmmm could you do a ls in that directory and post the results. Also are you sure that the init got completed without any issues? – Ronak Khandelwal Jun 03 '16 at 11:15
I have terminated the execution of the init because It looked like it finished it's job. I will try it again. Actually, should it take so long? – Sergey Onishchenko Jun 03 '16 at 11:24
First time it takes long enough to feel like nothing is happening Ideally you'll get a index.android.js and index.ios.js and other such files let it run to completion go out for a walk and then try again! – Ronak Khandelwal Jun 03 '16 at 11:35

Make sure you go into the directory having package.json
If you have deleted nodemodules try "npm install".
And don't forget the "init" in "react-native init MyApp". "init"
initializes the package.json.

I did everything correct while setting up, but was unable to run the android code. Just make sure while running the command react-native run-android that, you are inside the AwesomeProject folder created by the react-native init AwesomeProject command.

The folder by default for my PC was under C:\Windows\system32\AwesomeProject in Windows.

Hope it helped for the first timers :)

If you guys have latest react native version and facing this error

"UNRECOGNIZED COMMAND run-android".

then run follow these steps it will definitely help you.

Step: 1 -> create a new file "react-native.config.js" in the project root directory.

Step : 2 -> Inside "package.json" you have "assets" array inside "rnpm" object cut these assets from this and paste in your "react-native.config.js". i-e:

module.exports = {
assets: ['./assets/fonts'],
}

Step : 3 -> Remove "rnpm" object from "package.json".

Step : 4 -> Replace your "scripts" with below mentioned "scripts" inside "package.json"

"scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest",
    "android": "react-native run-android",
    "ios": "react-native run-ios",
    "lint": "eslint .",
    "android:prod": "npx react-native run-android --variant=release",
    "ios:prod": "react-native run-ios --configuration Release"
  }

That's it Happy Hacking..............
