更新了 React Native，在 Podfile 中找不到“boost”依赖项

Question

正如我的问题标题中提到的，我在更新到 React Native 0.66 后尝试运行 pod install，但我不断收到以下错误：

[!] CocoaPods could not find compatible versions for pod "boost":
  In Podfile:
    RCT-Folly (from `../node_modules/react-native/third-party-podspecs/RCT-Folly.podspec`) was resolved to 2021.06.28.00-v2, which depends on
      boost

    React-cxxreact (from `../node_modules/react-native/ReactCommon/cxxreact`) was resolved to 0.66.0, which depends on
      boost (= 1.76.0)

Specs satisfying the `boost (= 1.76.0), boost` dependency were found, but they required a higher minimum deployment target.

我已经搜索了另一个引用“提升”的问题的高低，但我无法在任何地方找到它。我已经安装了boost-for-react-native 并添加到我的 Podfile 中，但它似乎没有解决任何问题。

如果我将 Podfile 中的部署目标更改为 11.0 甚至 14.0，我仍然会收到错误消息。

这完全阻止了我的项目的构建，所以如果我能得到任何帮助，那就太好了。

完整的 Pod 文件如下：

Answer 1

当我升级到 react-native 0.66.4 时，我遇到了同样的问题。从字面上得到确切的错误消息。

我的 Podfile 中缺少以下行：

pod 'boost', :podspec => '../node_modules/react-native/third-party-podspecs/boost.podspec'

添加后，我运行pod install 并解决了问题！

Answer 2

我最近在更新 react native 后遇到了类似的 boost 问题。在恐慌消退并喝了一杯好咖啡后，我能够通过以下方式解决：

1. 在 Xcode 中打开 <app_name>/ios/<app_name>.xcworkspace 文件。
2. 提高 iOS 部署目标（在我的例子中，我只达到了 10 个）。
3. 产品 > 清理构建文件夹，然后产品 > 运行。
4. 在问题导航器中找到 boost 错误，并确定错误在哪个 pod 下列出（在我的例子中是 RNReanimated）。
5. 更新与 pod 相关的 node 包（在我的例子中，npm update react-native-reanimated
6. 最后，运行pod install

执行这些步骤后，我能够让我的项目重新启动并运行。
