问题
I am trying to implement React Native authentication with Firebase using Expo. I am currently having following versions:
- Expo: 20.0.0
- npm: 5.4.0
- firebase: 4.3.0
I get the following error:
Error: React native is not installed. Please run
npm installin your project directory.
How I got here
Expo recommends npm version 4.6.1. (In fact, on Expo forum here in post about npm breaking apps, it has been advised to downgrade to 4.* version of npm). But firebase 4.3.0 fails to install with npm version 4.6.1. So I upgraded npm to latest 5.4.0. Firebase installed fine, but now I get above error in Expo. And here is error message from when I try to install firebase with npm 4.6.1:
Question(s)
- Can I use some older version of firebase which will work with npm 4.6.1? Which version would that be?
- Is there some other workaround (other then older firebase version)? Did anybody implement RN + Firebase + Expo successfully?
