反应原生初始化错误

Question

我正在尝试将 React-native 安装到我的 ubuntu 14.04。我已成功安装react-native-cli，但是当我尝试运行react-native init reactApp 时，trene 出现错误：

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

我该如何解决？

Answer 1

您肯定需要安装 Node 4.0 或更高版本。实际上，它甚至会在您的控制台输出中说明。

这是我在 Ubuntu 上安装 Node 的方式：

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

祝你好运！

Answer 2

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