Description

I'm creating a new App, and want to use typescript template. According to the init doc, I tried the following :

# This does NOT work, cli will throw an Error
npx react-native init Demo --template react-native-template-typescript

Then I tries this

# No error, but typescript is not configured
npx react-native init Demo --template typescript

So, how can we init app with typescript enabled?

Looks like npx react-native resolves to a globally installed react-native-cli. Please remove it, it's not needed anymore.

@youngjuning

Please run below commands

• npm list -g --depth=0
• yarn global list

and paste the result here, bc probably you have installed old version of RN cli.
In my case I needed to use below commands to uninstall wrong version of cli

npm uninstall -g react-native
npm uninstall react-native-cli -g
yarn remove global react-native-cli

and then run

npx react-native init MyApp --template react-native-template-typescript

@troZee's solution worked for me, just correcting their typo to save people a few googles (the global command must immediately follow yarn):

npm uninstall -g react-native
npm uninstall -g react-native-cli
yarn global remove react-native-cli
