react-native - 摇动手势后，操作表中缺少 "Enable Live Reload"和“启用热重载”选项

Question

选择模拟器的“摇动”手势以提出重新加载/检查器/监视器选项时，缺少“启用实时重新加载”和“启用热重新加载”选项。

我运行了一个旧版本，以及一个新实例(相同的代码)。新实例没有显示最有用的选项。

到目前为止，我已经删除了 iOS 构建目录并重置了所有内容:

rm -rf ios/build && watchman watch-del-all && npm start -- --reset-cache

并重新运行 yarn ，

yarn start --reset-cache

重新启动，一切都无济于事。

我正在使用 React Native 0.56.1

我在右侧包含了一个旧模拟器窗口的屏幕截图，该窗口保持打开状态，以及一个使用相同代码库的新实例。

如果缺少 Hot Reload 或 Live Reload 选项，这是因为如 react-native 博客中所述

When we asked the React Native community about common pain points, one of the top answers was that the “hot reloading” feature was broken. It didn’t work reliably for function components, often failed to update the screen, and wasn’t resilient to typos and mistakes.
