Missing Script when I run npm start to create React app

Question

I'm trying to run the React server by running npm start

When I do this I get a missing script error:

λ npm start npm ERR! missing script: start  npm ERR! A complete log of this run can be found in: npm ERR!     C:\Users\Aristophanes\AppData\Roaming\npm-cache\_logs\2019-05-15T11_34_47_404Z-debug.log 

Full error log:

Answer 1

global installs of create-react-app are no longer supported.

do it:

npm uninstall -g create-react-app

now do it:

npm install create-react-app

now create your app

npx create-react-app yout-app-name

Answer 2

Installing create-react-app globally is now discouraged. Instead uninstall globally installed create-react-app package by doing: npm uninstall -g create-react-app (may require run as sudo if you get permission related errors or manually delete package folder if this command didn't work for you. Some users have reported they had to delete folders manually)

Then you can run npx create-react-app my-app to create react app again.

npx is available for npm version >= 5.2
