Can't Scaffold TypeScript Project Anymore...

[JimLynchCodes]

When I run the command:

npx create-react-app cra-example-app --template typescript

it ends with this strange message and creates a js project that doesn't seem to build...

The react-scripts version you're using is not compatible with the --template option.

The command works properly. It appears it could be a node version problem based on the npx installation?

I used node v14. Could you give more details on the versions you are using?

Also, the name of the project is really not nice. Add more specifics and be nicer please :)

Created git commit.

Success! Created cra-project at /OpenSource/cra-project
Inside that directory, you can run several commands:

  npm start
    Starts the development server.

  npm run build
    Bundles the app into static files for production.

  npm test
    Starts the test runner.

  npm run eject
    Removes this tool and copies build dependencies, configuration files
    and scripts into the app directory. If you do this, you can’t go back!

We suggest that you begin by typing:

  cd cra-project
  npm start

Happy hacking!

try this npx clear-npx-cache

[mikeaustin]

UPDATE: Running npm cache clean --force did fix the issue with using nxp create-react-app.

Hmm, "npx create-react-app foo --template typescript" is creating a folder with package.json, package-lock.json and node_modules and that's it. I've done npx clear-npx-cache and nothing changes. Using npm 6.14.16 / node 14.19.0.

package.json is package.json only has a few properties:

{
  "name": "container",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^18.1.0",
    "react-dom": "^18.1.0",
    "react-scripts": "5.0.1"
  }
}

If I install create-react-app globally with npm install -g create-react-app, it seems to work correctly. So this is not an issue with create-react-app, but it is a bad experience. What else would cause this issue?

i had a similar problem when running thru npx or yarn create:

$ npx create-react-app ./client --template typecript

Aborting installation.
  npm install --no-audit --save --save-exact --loglevel error react react-dom react-scripts cra-template-typecript has failed.

and indeed, first installing globally yarn global add create-react-app and then running the executable directly -- solved the problem.

very strange behavior...
