Undefined is not an object (evaluating 'nativeVersion.major')

Expo SDK
1

hey there. I need help on starting a react app on Expo
I caught the following error: undefined is not an object evaluating nativeVersion. I tried to update all packages and node version, as i saw on this topic: https://github.com/viromedia/viro/issues/41. But didnt work.
I dont know what to do.
Does have anyone an idea and could help me?

@edit
Im adding some more informations:

not sure what you’re doing when starting this project but it’s almost certainly not the right thing :stuck_out_tongue: just run exp init SomeProject or download xde and create a new project

make sure the dependencies are set correctly in package.json and that the sdkVersion is set correctly in app.json

Well, the problem is solved. After all I had to update all packages, node and expo and update the SDK version.
Thks @notbrent
Could you explain where I can check the compatibility between expo and SDK´s versions?
Now I am getting a new error, because react has not backward compatibility and I have to migrate my project.
But I will open a new topic about this.
