npx create-react-app 使用旧版本运行

Question

The latest version create-react-app is 4.0.3 but when I run npx create-react-app my-app it uses version 1.5.2 and also doesn't run with templates. I don't have any global installation of it and have tried uninstalling it using npm uninstall -g create-react-app .

My npm version is 7.21.1 and node version is 16.9.1

How can I make it work? Please help.

EDIT: There are 58 vulnerabilities while creating the app and this comes at the end -

A template was not provided. This is likely because you're using an outdated version of create-react-app.
Please note that global installs of create-react-app are no longer supported.
You can fix this by running npm uninstall -g create-react-app or yarn global remove create-react-app before using create-react-app again.

The folder also doesn't have the src folder just the node_modules folder and package.json file.

While running npm audit fix I get this -

Short version:

npx clear-npx-cache

Temporary solution:

npx create-react-app@latest my-app

Now for the explanation. I think npx is running an old version of create-react-app on your computer. The first time you do npx create-react-app , the package is installed in the cache. npx does not check for newer versions if the package is cached. You can sidestep this issue by adding @latest. This forces npx to fetch the package even if it is cached.

A better solution is to clear the cache. There are other guides about how to find and remove the cache folder on windows and macos. The package clear-npx-cache does this.
