Reactnative 如何使用 Expo 清理(reset cache)

我正在构建一个简单的React原生应用程序，其中create React原生应用程序仅使用React导航和base-64(base 64编码/解码)作为依赖项.随着时间的推移，启动应用程序变得越来越慢，现在有时会在"启动packager…"上卡住(等待约30分钟)运行NPM后启动.

我试着用"npm启动--reset cache"来启动它，但没有任何改变

一旦启动并运行，我在DevTools或terminal中不会收到任何错误或警告.此外，应用程序的性能也没有问题

我该怎么做才能让NPM像以前一样顺利、快速地开始？我是否可以采取任何常规步骤来解决此问题？

这是我的Package.json
