Why is the package not being installed?

Question

JavaScript

Has anyone experienced this? My npm view @babel/traverse shows version 7.6.3 and current version is 7.7.0.
Because of this, the @babel/core package is not installed, because it has version 7,7,0 depending on it, but I can't see it.
npm cache verify did
package-lock.json removed.
Here is the current package.json

If you need a specific version, try forcing it with
npm i -D @babel/[email protected]
