EPERM: operation not permitted, chmod @react-native-community iOS

I am using React 16.8.6 and react-native 0.59.6. iOS.

While typing react-native --version or anything prefix with react-native, it is showing the following error.

internal/fs/utils.js:220
    throw err;
    ^

Error: EPERM: operation not permitted, chmod '/usr/local/lib/node_modules/react-native/node_modules/@react-native-community/cli/build/commands/server/external/xsel'

}

I cleaned the project. Restarted it.

Deleted npm package and reinstalled it.

Tried npm install -g react-native-cli.

I have react-native-community/cli version 1.12.0 in package.lock.json dependancies.

I don't have any clue about what to do. I am not able to do link any libraries and other stuffs which requires react-native keyword.

Moreover, If I run it with sudo like sudo react-native --version, it is giving like below mentioned.
