当然，我已经安装了反应本机。 X-45454545 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045 X- 20045。

我附加了更详细输出的屏幕截图。

感谢提前！

解决方案

这使我有一天好的1天。问题是我的文件层次结构中有一个.babelrc文件，它干扰了babel解析。摆脱了这一点，没关系。 react-native默认使用es2015，因此不需要.babelrc。

When I'm trying to start a new react-native project from scratch I'm getting this message.

/Users/jorgevenegas/Dev/Projects/testreact/List/node_modules/react-native/node_modules/babel-core/lib/transformation/file/options/option-manager.js:327
          throw new Error("Couldn't find preset " + JSON.stringify(val) + " relative to directory " + JSON.stringify(dirname));
          ^

Error: Couldn't find preset "es2015" relative to directory "/Users/jorgevenegas/Dev/Projects"

I have installed react-native-cli, of course. Using node v4.2.1, react-native 0.1.5, watchman and flow installed too.

Seems to be something related to babel. I can't figure out the reason, though.

I'm attaching a screenshot with a more detailed output.

Thanks in the advance!

解决方案

This bugged me for a good 1 day. The issue was I had a .babelrc file up in my file hierarchy which was interfering with babel parsing. Got rid of that and it was fine. react-native uses es2015 by default so .babelrc is not required.
