React Native 不支持 Windows 上的开发（还）？
React Native does not support development on Windows (yet)?
我相信大多数人都对 React Native 现在终于支持 Android 感到非常兴奋。
但是，它不支持在 Windows 机器上进行开发，这会让人非常失望——在许多情况下，这会阻止大公司采用 React Native，因为大公司不能只改变他们的主要 OS.
我挖掘了一下，似乎不难得到它 运行 宁 Windows 无论如何。
在 react-native-cli index.js 中从出生点更改为 requirejs.exec，如下所示：
spawn.exec(cmd + ' ' + args.join(' '), function(code, output){
if (code !== 0) {
cb(new Error('Command exited with a non-zero status ' + code + '\n' + cmd + ' ' + args.replace(',', ' ')));
} else {
cb(null);
}
});
//var proc = spawn(cmd, args, {stdio: 'inherit'});
//proc.on('close', function(code) {
// if (code !== 0) {
// cb(new Error('Command exited with a non-zero status'));
// } else {
// cb(null);
// }
//});
此更改使我能够 运行 react-native run-android 而没有任何可见错误。它会启动模拟器和应用程序。
运行在 Windows 上唯一缺少的最后一块是：
为什么开发服务器不工作 - 或者为什么应用程序不能连接到它？
我收到 "Unable to download JS Bundle..." 红屏死机。似乎 react-native run-android 未能启动它，即使它打印 Starting JS server...。请参阅底部的完整输出。
有人可以帮忙解决这个问题吗？
谢谢

我想我们已经很接近 运行Windows 了，我只需要最后一点帮助就可以了。
请帮忙
更新：自 0.14 版（2015 年 10 月）起，Windows 由于社区的出色工作，开发成为可能（details）。
Windows 官方尚未支持，请参阅 Getting Started 上的文档。
我们希望尽快发布该版本，并首先关注 Mac OS。
社区中的人们让 React Native 在 Linux 上工作，并进行了一些最小的更改（我们将很快记录这些）并且看起来有人也刚刚在 Windows 上工作：
我通过安装 cygwin 和 运行 找到了修复它的方法：

希望对大家有所帮助。
