Angular 4 new project creation error

Question

I've recently started learning Angular 4. I have installed node and angular-cli on my machine. The problem is while I am doing an ng new and here I get the following error:

npm WARN codelyzer@3.2.2 requires a peer of @angular/compiler@^2.3.1 || >=4.0.0-beta <5.0.0 but none was installed.
npm WARN codelyzer@3.2.2 requires a peer of @angular/core@^2.3.1 || >=4.0.0-beta <5.0.0 but none was installed.
