React-Native不能GET /和JS Bundle

Question

這是我運行react-native start時得到的輸出，正如您所看到的，它給出了404錯誤。

我試過用chrome打開頁面，它說Cannot GET / 。

即使通過wifi連接設備並輸入設備的IP地址，該應用程序也無法在移動設備上運行。 它被困在紅色屏幕上說Unable to load JS Bundle.

怎么了？

我看過的問題：

反應原生android無法加載JS包

但它不起作用。

Answer 1

如果你想確保打包器正在加載你需要導航到http://localhost:8081/js/index.android.bundle?platform=android 。 如果您仍然獲得404，那么您的網絡配置很可能出現問題。

如果你可以在網上提起它，請在手機插入USB adb reverse tcp:8081 tcp:8081 。
