react-native：構建因異常而失敗

Question

從0.17升級到0.19后，每次我嘗試使用（ react-native run-android ） build application時，我都會收到此錯誤。 我已經嘗試降級到0.17，但它沒有幫助，問題是一樣的。 我也在網上搜索過但找不到與我的問題類似的東西。 我想問題是gradle而不是本身的react-native但我不知道如何解決它？

這是錯誤：

Starting JS server...
Starting the packager in a new window is not supported on Windows yet.
Please start it manually using 'react-native start'.
We believe the best Windows support will come from a community of people
using React Native on Windows on a daily basis.
Would you be up for sending a pull request?

幾天前我遇到了同樣的問題。 您似乎遇到連接問題，速度緩慢，或者您的ISP阻止了網站（出於任何原因）或者您所在的國家/地區（如中國）進行了過濾。 嘗試使用代理並重試，它對我有用。

順便說一句，問題不在於本地反應，而是與gradle有關。 社區將在v0.21中包含這些帶有react-native軟件包的jar文件，本周即將發布，我希望你的jcenter問題能得到解決。
