Installing react-native using create-react-native-app gives error

Question

I want to learn React-native and I am following the official docs. and I am using create-react-native-app for installation.

I am also working for a project in reactjs which is also installed using create-react-app. When I tried to install react-native using cmd:

npm install -g create-react-native-app

I see the following error

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules
npm ERR! path /usr/local/lib/node_modules
npm ERR! code EACCES
npm ERR! errno -13
npm ERR! syscall access

My mac already has a node_modules which is created during Reactjs Installation.

And when I run npm install create-react-native-app the modules are installed but the cmd for creating react native app didn't get recognized.

$create-react-native-app hello

-bash: create-react-native-app: command not found

Is it possible to work both in react-native and reactjs?

Anything with -g requires a global install and requires sudo access. Because this installs globally.

sudo npm install -g create-react-native-app
