Solution:

These warnings will not affect your project from the user end, and thus we can just ignore them as long as our project has been compiled successfully. However, if your project run into errors and cannot be compiled smoothly, you may have installed the wrong version of node.js. Please reinstall it from here and follow the updated instructions in React-VSCode.md, which should solve the issue.
