    This is apparently an inherent problem with npm, npx. If your computer account username has a space ' ' in it, the command will not work. I am facing the same issue and I haven't find a solution yet. – AG_HIHI Dec 29 '19 at 14:36

When you install create-react-app globally, you do not need to run the command with npm/npx/yarn. It is its own binary, so all you should have to type is "create-react-app directory" where 'directory' is the directory you want to create the react app within.

Also, it looks like the command you're running is "create react-app" rather than "create-react-app", make sure you do not miss the first dash or you will not be running the correct command.

delete node.js and download from node.js LTS and when you install in you computer click all the approval boxes and check the version of npm>5 and node.js and your internet ,good luck;)

Open Windows PowerShell(Admin) then paste this and make sure to change name from Aamir~Naved to your name and similary if your name has more than one word,kindly add a tilde(~) in between:

npm config set cache "C:\\Users\\Aamir~Naved\\AppData\\Roaming\\npm-cache" --global

then paste this:(make sure to edit directory_name with name of the directory you want to create react app in. for example: C:\learnreact

npx create-react-app directory_name

I just went through this and found that all I had to do was to give write permission to the folder in which I wanted to create the app. Hope it's that simple for you.
