How do I create a React Native project using Yarn?

I am running the following commands in the DOS console on a Windows 7 (64-bit) machine.

npm install -g yarn
yarn add global react-native
yarn add global react-native-cli

react-native init sample

After running react-native init sample, the console was closed.

The error log shows:

D:\Mobile>"$basedir/../../Users/pramaswamy/AppData/Local/Yarn/.global/node_modules/.bin/react-native.cmd"   "$@" 

D:\Mobile>exit $? 

I think you're adding global dependencies wrong, and you shouldn't need to install react-native, globally or locally. react-native init will create a package.json with react-native listed as a dependency.

You should be able to install react-native-cli globally with yarn global add react-native-cli, not yarn add global react-native-cli.

You should be fine with running the following:

npm install -g yarn
yarn global add react-native-cli
react-native init sample

NEW SEP 2019, now it's more simple, use node10 and expo: (easy way)

npm install -g expo-cli

*to create project:

    expo init AwesomeProject

    cd AwesomeProject
    npm start

*install the app 'expo' on your phone, and scan the qr code for the project and you can start to view your app

UPDATE OCT 2018 Create React Native App (now discontinued) has been merged with Expo CLI You can now use expo init to create your project. See Quick Start in the Expo documentation for instructions on getting started using Expo CLI.

Unfortunately, react-native-cli is outdated. Starting 13 March 2017, use create-react-native-app instead. Moreover, you shouldn't install Yarn with NPM. Instead, use one of the methods on the yarn installation page.

1. Install yarn

Via NPM. According to its installation docs, you shouldn't install yarn via npm, but if necessary, you can still install it with a pre-v5 version of npm.

UPDATE 2018 - OCTOBER

Node 8.12.0 and NPM 6.4.1 is already compatible with create-react-native-app. Really some minors previous versions too. You don't need more downgrade your npm.

On Ubuntu.

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

On macOS, use Homebrew or MacPorts.

brew install yarn
sudo port install yarn

2. Install the Create React Native App

yarn global add create-react-native-app

3. Update your shell environment

source ~/.bashrc

4. Create a React native project

create-react-native-app myreactproj

You got the order wrong. You should be

yarn add global react-native-cli
yarn add react-native
react-native init sample
