反应本机初始化错误

Question

I'm trying to install React-native to my ubuntu 14.04. I have sucessfully installed react-native-cli , but when I'm trying to run react-native init reactApp trene is an error:

pavlov@pavlov-System-Product-Name:~$ node -v
v0.12.7
pavlov@pavlov-System-Product-Name:~$ react-native init reactApp
prompt: Directory reactApp already exist. Continue?:  (no) y
This will walk you through creating a new React Native project in /home/pavlov/reactApp
Installing react-native package from npm...
You are currently running Node v0.12.7 but React Native requires >=4. Please use a supported version of Node.
See https://facebook.github.io/react-native/docs/getting-started.html

How can i fix it?

Answer 1

You definitely need to install Node 4.0 or higher. Actually it even says it in your console output.

Here is how i installed Node on my Ubuntu:

sudo apt-get install curl
curl --silent --location https://deb.nodesource.com/setup_4.x | sudo bash -
sudo apt-get install nodejs

Good luck!

Answer 2

转到https://nodejs.org/en/并下载最新版本，在本例中为v4.4.3。
