以这种方式创buildReact Native应用程序出了什么问题?

我正在尝试创build一个基本的React Native应用程序。 虽然我可以创build该项目,但不会在模拟器中运行。

应用程序加载后,立即退出。 如果我删除node_modules并且执行npm install来下载新鲜的所有模块,我将会看到应用程序重新加载Javascript。 然后当它达到100%,它立即退出。

我用来创build应用程序的步骤如下:

 $ react-native init demo1 $ cd demo1 $ react-native run-ios 

这就是字面意思。 我正在使用以下版本的工具:

 $ node --version v6.11.2 $ npm --version 3.10.10 $ react-native --version react-native-cli: 2.0.1 react-native: 0.48.0 

完整的日志在这里 。 我究竟做错了什么?


调查这更多,事实certificate,Xcode项目失败,堆栈跟踪:

这是一些错误还是这是我做的?

这似乎是一个0.48的问题。 尝试使用0.47.1,你应该没问题。

 react-native init demo1 --version react-native@0.47.1 

此问题已在RN 0.48.1中得到解决。 如果您创build了一个新项目(截至2017年9月4日),您不应该遇到这个问题。
