First Expo project throwing error after npm start

npm install expo-cli error
expo start not working
expo start error: spawn cmd enoent
this command requires expo-cli error
expo error unrecognized command start
expo start error invalid regular expression
your project is in sdk version >= 33.0 0 but the expo package version seems to be older
expo init not working

I followed instructions to install Expo on my Windows 10 machine. I'm running node version 10.14.0 on my machine.

After I issued expo init command and created the first project, running npm start shows a message that reads:

This command requires Expo CLI. Do you want to install it globally [Y/n]?

Strange thing is that I'd already installed the latest version of expo-cli globally. Running expo-cli --version in the project folder gives me the version of expo-cli which is 2.5.0.

From here, it gets worse. No matter what I choose, I get the following error:

Any idea how to fix this issue?

I had the same issue, first run:

npm i expo-cli


npm start

Worked for me

'Unable to start server' on npm start on create-react-native-app , native app using create-react-native-app and error on when run npm start in app and show QR code which a mobile can connect through expo app. You can get information on how to open an issue for this project with:  Solution is just use expo-cli start, dont use npm start or yarn start.So it works without problems for now. So if you want to create a react-native app with expo without problems , steps are : expo-cli init [project-name] cd [project-name] install any package if you need => npm install package or yarn add package

In my case I had the same error, so I went to the expo documentation (, to see the error.

First I logged into the expo:

expo login --username -u [username] --password -p [password]

and then I checked if I was logged in:

expo whoami

Second I followed this help that I found on stackOverflow: How to resolve the error on 'react-native start'

Hope this helps.
