react-native run-android is unrecognized

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?

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 https://stackoverflow.com/questions/36119358/react-native-command-run-ios-unrecognized/44851272#44851272)

the answer is easy nad it is not because of any bug at all.

make sure you are in correct directory 

if in current directory there is not any react native app ,it gives you this error

I just ran "yarn" with no arguments and it fixed it.

Please try this command:

npm install --save react-native

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.

> react-native run-android is unrecognized

Make sure that you have installed npm or use in your project directory

npm install

you have to update your npm. To do that

npm install npm@latest -g

try "yarn install". It will install the missing files in node_modules

It worked for me

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

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. !!!

1. 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

2. 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

3. 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

npx react-native run-android

Use of npx will pick local npm node_modules directory

Do npm install then run react-native run-android

• 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.

You can solve this by yarn or npx:

yarn react-native run-android
npx react-native run-android

Step 01 : Make sure that you are in right directory
Step 02 : npm install run this command
Step 03 : npm audit fix run this to fix issues

Try deleting node_modules folder and then run the commands again

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 :)

You need to update the project with the latest version of react-native. Just run this command.

npm install --save react-native@latest

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..............

Everything has already tried like me? Then try again once "Yarn install after deleting node_modules". It worked for me.

Uninstall react-native from global

$ npm uninstall -g react-native

Then

Install react-native to global

$ npm install -g react-native-cli

That worked for me

react-native run-android

They have made some unnoticeable changes. For instance run-android(now) run android(before).

Try to delete "package-lock.json" and re-run "npm install", then try your command, It should work

I got this error because I had parenthesis in the path "(" and ")". Possibly this error is thrown for other special characters as well.

Ensure you run the command in the projects' terminal, preferably the Android IDE. Run the adb devices to know your active devices as well

If your package.json file is containing any comment then this error is comes. So remove all comments from package.json and then run command it will work.

Also try to run command npm install --save then it will log if other error there. If any others error also there, then first fix it and then run command it will work.

In Android Studio click in Tools -> SDK Manager -> in System Settings click in Android SDK -> choose tab SDK Tools, then enable Android SDK command line tools (lasted). It work for me!

Open your React Native Project Root Directory and locate android -> app -> build -> intermediates -> signing_config -> debug -> out -> signing-config.json

Delete signing-config.json file

And rebuild your application.

react-native run-android

First thing you need to delete node_mouldes and package.lock.json and do yarn install after that if you're using Windows OS you need to use PowerShell not git bash and write this command "react-native run-android"

Install npm again to latest react-native init project_name cd project_name open android studio the same android folder inside your project_name react_native run_android will work now

for the last time your project was working fine and now you got this error suddenly and you have Node modules already installed then just trynpm install --save react-native this work for me

In my case, I forgot to run npm install before running react-native run-android. I know this is a silly mistake but it may help.

In my case, there was an extra comma in the Package.json in the "dependencies" section. "use-is-mounted-ref": "^1.4.0",

This made react to not be able to update, install anything. Last line shouldn't have any comma

Okay, I tried many of the tough solutions, also many mentioned above, But yarn install did the job greatly.

> yarn install

For my case, I just forgot to access the project folder using "cd" command after generating the project.

I forgot to change the directory first after run react-native init command. When I ran command inside the react-native project directory it worked post that run the command npx react-native run-ios or run-andoid, it will work.

error Unrecognized command "run-android". info Run "react-native --help" to see a list of all available commands.

Firstly you have run cmd line as a admin before enter "npx react-native init " command. Then try other solutions.
