尝试使用 expo 构建 create-react-app 项目，引发有关 react-native 的错误

Question

I've created my react app using create-react-app, and was trying to use expo, but its throwing errors when I try and build it using expo build:android :

Error: Can't find react-native in package.json dependencies
Error: React Native is not installed. Please run `npm install` in your project directory.

Do I need to start over with a react-native project, or is there a way to continue on and get this project published?

Answer 1

I suggest you create your project using the expo docs :

npm install expo-cli --global

expo init my-new-project
cd my-new-project
expo start

Answer 2

Try this:

• Remove node_modules folder.
• run "yarn install".
• run "expo start".

This looks like a similar issue on this github error
