当我运行npx react-native projectname时，项目仅部分创建。
现在当我运行bundle install时，我得到:
1. Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
2. An error occurred while installing ffi (1.15.5), and Bundler cannot continue. Make sure that "gem install ffi -v '1.15.5' --source 'https://rubygems.org/'" succeeds before bundling.

是的，我已经安装了ffi 1.15.5(下面的截图)，但它仍然说我没有它

我印象深刻的是，开始一个项目是多么的困难。谁来帮帮我尝试使用expo。https://docs.expo.dev/get-started/create-a-new-app/
npx create-expo-app my-app运行这将创建一个名为"my-app"的新应用。
或者你可以运行npx create-expo-app --template从一个starter应用开始。我喜欢用'Navigation (TypeScript)'。
expo链接将解释如何设置您的应用程序以及如何在模拟器中运行您的应用程序或在手机上使用expo go应用程序。这是一个很好的资源。
希望有帮助!
