1. Delete the whole folder including node_modules.

2. Run npm install again.

Good luck.

CodePudding user response：

As the information provided, i didn't get the idea like what's the exact problem . But you can try below methods :

1. npx create-react-app my-app( IF you are using node version >=8

2. Add C:\Users\ugur\AppData\Roaming\npm OR C:\Users\Admin\AppData\Roaming\npm\node_modules to windows PATH variable.

3. Use this npx create-react-app new_app --use-npm

4. If you didn't understand the 2nd one solution or maybe path will be different they use below method :

=>Check your global directory by using command npm root -g

=>check the folder, will it have .cmd of your installed packages.

=>If yes, Please copy the path of folder and put in path of user variable
