使用Yarn或NPM进行本机反应找不到@ expo / bunyan。 我该怎么办？

The create-react-native-app does not support npm5 currently because npm5 is buggy. you can use npm4 or latest npm stable version available.

I have tried to install create-react-native-app library on my system having the following configuration:

node -v

v9.4.0

npm -v

5.6.0

Before installation once remove the node_modules and clear the npm-cache .

Set npm registry using npm config set registry http://registry.npmjs.org/ command.

Then try to install using npm i react-native-scripts --save --use-npm --verbose command.

If you want to install the same library using yarn then you can use yarn global add create-react-native-app command for the same.

Hope this will help you!
