Solution 1

As you can see on https://status.npmjs.org, 4 packages are down at this moment.

They've fixed the issue but we need to wait for CDN world propagation.

Don't update your packages or install new one to fix this.

Solution 2

Try configuring npm using this npm config set registry https://skimdb.npmjs.com/registry

Solution 3

I think you triggered wrong command, check spelling of the command npx react-native run-android then it will work.

Solution 4

100% (solution) : npm set registry https://registry.npmjs.org/

There are some errors going on in the npm registry. You can check the status here: status.npmjs.org, it should be solved soon. Don't install other packages or use other registries to patch that, you will mess things up :)

How can I reset it to the default registry later?

[plamenti]

npm config set registry registry.npmjs.org

In order to switch between different .npmrc files (which can point to different registries) it is better to use npmrc tool - npmjs.com/package/npmrc For more information check here - docs.npmjs.com/…

I had the same issue, after a couple of times it worked, without me changing anything.
