无法手动或自动构建main.jsbundle文件

Question

我试图在以./index.js作为条目文件的命令行（MacOSX Mojave 10.14.4（18E226））中手动构建/ios/main.jsbundle文件。但是我没有成功。

然后我在Xcode（版本10.2.1（10E1001））中使用此文件。

我正在使用根目录中的以下命令来构建main.jsbundle：

$ react-native bundle --entry-file ./index.js --platform ios --dev false --bundle-output main.jsbundle

OR

$ react-native bundle --entry-file ./index.js --platform its --bundle-output main.jsbundle

这与--verbose标志一起出现：

Loading dependency graph, done.

我试图找到一个类似的问题，但没有。

我还试图清理缓存，清理看守员的手表，杀死地铁捆绑器，重新启动Xcode，更新brew，npm。

这些是我的文件：
