How to install React Native?

Question

React

Mac Sierra. I'm trying to install according to the instructions from the official site, access rights errors constantly appear (in the folder with documents). One of them - ".babel.json" - fixed as here , but this is not a normal situation, I can not understand the reason.
PS: xcode and android studio installed, javac 1.8.0_91

react-native run-ios

Answer 1

Off docks is the best instruction. In fact, the poppy also launched everything in 5 seconds without any problems.
Well, it would be very logical after the phrase "errors are coming" - put them here and in fact already see what and how.

Answer 2

Try create-react-app I think it will make things easier

Answer 3

Never had a problem with react native. As an option, try to run from the desktop. Or create a project with admin rights.

Answer 4

You can see 2 conspicuous errors:
1. One emulator is already running (it's not scary)
2. No read / write
access rights Your account may not have enough access rights to run. Try as an option to run with sudo -

$sudo react-native run-ios

or via Xcode

$open ios/ProjectName.xcodeproj
And run: CMD⌘ + R
And don't forget to install XCode command line tools :)
