以这种方式创建 React Native 应用程序有什么问题? [英] What is wrong with creating a React Native app this way?
问题描述
我正在尝试创建一个基本的 React Native 应用程序.虽然我可以创建项目，但它不会在模拟器内运行.
I'm trying to create a basic React Native app. While I can create the project, it will not run inside the simulator.
应用加载后，它会立即退出.如果我删除 node_modules 并执行 npm install 以下载所有新模块，我将看到应用程序重新加载 Javascript.然后当它达到 100% 时，它立即再次退出.
After the app loads, it immediately quits. If I remove node_modules and do npm install to download all the modules fresh, I will see the app reload the Javascript. Then when it hits 100%, it immediately quits again.
我用来创建应用程序的步骤如下:
The steps I used to create the app are as follows:
$ react-native init demo1
$ cd demo1
$ react-native run-ios
字面意思就是这样.我正在使用以下版本的工具:
That's literally it. I'm using the following versions of tools:
$ node --version
v6.11.2
$ npm --version
3.10.10
$ react-native --version
react-native-cli: 2.0.1
react-native: 0.48.0
完整日志位于此处.我做错了什么?
The full log is here. What am I doing wrong?
进一步调查，结果发现 Xcode 项目失败并带有堆栈跟踪:
Investigating this more, it turns out the Xcode project fails with a stack trace:

这是某种错误还是我做的?
Is this some sort of bug or is this something I did?
推荐答案
这似乎是 0.48 的问题.尝试使用 0.47.1，你应该没问题.
This seems to be a 0.48 issue. Try using 0.47.1 and you should be fine.
react-native init demo1 --version react-native@0.47.1
