I have solved this problem by running

$ npm uninstall -g create-react-app

then

$ npx clear-npx-cache

then

$ npm install -g create-react-app@5.0.0

and then finally it was able to use:

$ npx create-react-app my-app

If you're using npm>5 and still getting this error. This might be you have installed old npm and then updated. Tried to clear the npm cache with the below command. It should work like charm.

npx clear-npx-cache

I got same issue and I fixed it by running the following commands:

npx clear-npx-cache
npm cache verify

Go to"..\npm-cache" folder that you get its path from previous command and delete everything

npm install -g npm@8.3.0
npx create-react-app your_app_name

I was having the same problem and no matter what I tried (i.e. clearing cache, uninstalling -g create-react-app, etc..) nothing worked.

I had to use:

$ npm uninstall -g create-react-app

and

$ npm uninstall create-react-app

and then I was able to use:

$ npx create-react-app my-app

I know it seems simple but this was the only thing that worked for me.

If you still receive the same error after trying the other answers solutions try the following:

Go to the path where npm install packages globally.

• On macOS or Linux it's usually: /usr/local/lib/node_modules
• On Windows: C:\Users\USER_NAME\AppData\Roaming\npm\node_modules

Search for create-react-app folder and delete it. You might need to delete create-react-app related files from parent folder:

• /usr/local/lib/
• C:\Users\USER_NAME\AppData\Roaming\npm\

You may also try the 'npm root -g' command to get the path, however, for me the returned path wasn't the correct one for some reason.

npx clear-npx-cache //CMD USED TO NORMALPROCEDURE TO GO

You will have to clear the npx cache to make it work.

You can locate the location of the folder where create-react-app is installed using npm ls -g create-react-app.

Also, to clear the cache, refer to this answer in How can I clear the central cache for `npx`?

Try running npx clear-npx-cache to clear your npx cache and then running the npx create-react-app your-app command.

Also have a look at this answer on clearing the cache.

Additionally, it might be worth trying to force the latest version with:

npx create-react-app@latest my-app --use-npm

I have resolved with the following steps:

1. npm uninstall -g create-react-app

2. npx clear-npx-cache

3. npx create-react-app myapp

I tried both and they all works fine. You can try any of them.

npx create-react-app@5.0.0 my-app or npx clear-npx-cache

To clear a cache in npm, we need to run the npm cache clean --force command in our terminal:

npm cache clean --force
npx clear-npx-cache

clean: It deletes all data from your cache folder.

Solution 1: Force to the latest version

Just try to run the create command with force to the latest version. Just like this:

npx create-react-app@latest_version my-app --use-npm

And the latest version is 5.0.0 so just try this command:

npx create-react-app@5.0.0 my-app

Now, your error must be solved.

Solution 2: Clear the cache

You just need to clear your cache and then you can create a new React project. First of all, clear the cache by running this command:

npx clear-npx-cache

If it does not work, use this and try again: Delete everything from this path.

C:\Users\Your_user_name\AppData\Roaming\npm-cache

On macOS (and likely Linux), it’s ~/.npm/_npx. You can drop it with:

rm -rf ~/.npm/_npx

Or try the command npm cache clean --force using administrator mode in your terminal. Now, just rerun your create command.

npx create-react-app your-app

Solution 3: Run this command

Just run this command one by one.

1. npm uninstall -g create-react-app
2. npm cache clean --force
3. npm cache verify
4. npx create-react-app my-app

(npx create-react-app@5.0.0 my-app) worked like a charm and its also much faster now then old react js

I followed the above suggestions but it didn't solve my problem. Below steeps solved my problem

1- Learn npm cache folder path:
npm cache verify
This gives you npm cache folder path: Cache verified and compressed (~\AppData\Local\npm-cache_cacache)

2- Go to"..\npm-cache" folder and delete everything

3- Cerate your project:
npx create-react-app my-app
