Creating React applications has become increasingly important in the web development community. React is a JavaScript library that is used to build user interfaces. React applications are highly efficient because of their component-based architecture and one-way data flow. To make things easier for developers, the React team has developed a tool called "create-react-app" which provides an easy way to create a new React project. However, sometimes even experienced developers encounter an error message saying "unknown command create-react-app". In this article, we will discuss what this error message means and what could be causing it.
