[問題] react 環境安裝

[lonelytea (霸氣逼人)]

各位好

我照著這個流程

https://read01.com/5oakmJ.html

去安裝

但要在react-native-cli

跑 npm install -g

卻出現錯誤

F:\RnDev\react-native\react-native-cli>npm install -g
npm WARN F:\RnDev\react-native\react-native-cli\node_modules\semver is not a
child of C:\Users\Pascal\AppData\Roaming\npm

請問這個要怎麼解決
