以這種方式創建React Native應用程序有什麼問題？

我正在嘗試創建一個基本的React Native應用程序。雖然我可以創建該項目，但它不會在模擬器中運行。以這種方式創建React Native應用程序有什麼問題？

應用程序加載後，它立即退出。如果我刪除node_modules並執行npm install下載所有新鮮的模塊，我會看到該應用程序重新加載Javascript。然後當它達到100％時，它立即退出。是

我用來創建應用程序的步驟如下：

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

這是字面上它。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

完整日誌是here。我究竟做錯了什麼？

調查這個多，事實證明Xcode項目失敗，堆棧跟蹤：

這是某種類型的錯誤或這是我做的事？

這似乎是一個0.48的問題。嘗試使用0.47.1，你應該沒問題。

react-native init demo1 --version [email protected]

此問題已在RN 0.48.1中修復。如果您創建了新項目（截至2017年9月4日），則不應該遇到此問題。
