An unknown error has arisen: "The page https://registry.yarnpkg.com/react-native-template-react-native-template-typescript cannot be located."

Once I uninstalled the react-native-cli, I attempted to start a React Native project with a typescript template using the following command:

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

However, I encountered an error message:

warning jest > jest-cli > jest-config > jest-environment-jsdom > jsdom

Answer №1

Get rid of the outdated react-native-cli

npm uninstall -g react-native-cli

Upgrade to the latest version from "react-native-community":

npm i -g @react-native-community/cli

Then, initialize your project with: 

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

Answer №2

Solved: I needed to uninstall react native cli with yarn as well

yarn global remove react-native-cli

Answer №3

Another way to tackle this is by using the --ignore-existing flag:

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

Answer №4

My favorite way to solve this

Erase

npm uninstall -g react-native-cli

Make a new directory for the project

mkdir [new folder] && cd [new folder]

Get all the necessary dependencies and it should be good to go

yarn init
yarn add react-native
yarn react-native init [Project Name] ...

Answer №5

From my experience working with Centos 7, it is essential to run the command as a root user

npx react-native init AwesomeTSProject --template react-native-template-typescript

within the designated project directory, followed by executing chown user -R folder. This will allow smooth installation of 

yarn add react-native- template-typescript
.
