Javascript – Creating React-Typescript project Failed

I’m having an issue trying to use create-react-app with the typescript template, although it was working in the past. When trying to use create-react-app with no template i.e JSX, it sets up perfectly. I can’t figure out what’s going on.

Here is what I’m getting:

PS E:GADReact-Basics-CoursesGadReact_ProjectsReact_Typescript> npx create-react-app my-typescript-project --template typescript


Creating a new React app in E:GADReact-Basics-CoursesGadReact_ProjectsReact_Typescriptmy-typescript-project.

I have tried updating npm, node, and tsc, but I’m still getting the same error.

    Try this command:

    npm config set legacy-peer-deps true

    Then retry your npx create-react-app command.

    Try running
    npm cache clean --force
    to clear the npm cache and then run the create-react-app command again.

    If it’s still not working, you can try creating the app without the template and adding TypeScript manually later:

    npx create-react-app my-typescript-project

    cd my-typescript-project

    npm install --save typescript @types/node @types/react @types/react-dom
