Solution 1:^[1]

I think you might be getting this errors because you have previously installed react-native-cli globally. So, first remove react-native-cli using following command:

npm uninstall -g react-native-cli

Now try creating project:

npx react-native init travelApp

Solution 2:^[2]

npm config set registry "https://registry.npmjs.org"

This worked for me!

Solution 3:^[3]

Check that you are using the correct node version ( >= 12.13.0 ):

node --version

If you are not using the correct version, install the latest using nvm and switch to that version.

Solution 4:^[4]

For me, the issue was using an older version of node. I upgraded to node v12, then tried installing again, and it worked.

nvm install 12

nvm use 12

and then

react-native init Project

Solution 5:^[5]

You need to upgrade the node version.

You can install >10.0 node.

Solution 6:^[6]

If you have already installed Node on your system, make sure it is Node 14 or newer.

Solution 7:^[7]

Try upgrading node version to latest.
