添加 crashlytics 和结构时出现重复符号链接器错误

Question

我在 pod 文件中同时添加 Fabric 和 Crashlytics。当我更新 pod 时，我收到带有重复符号的链接器错误。我在这里发现它在 Fabric.framework 和 Crashlytics.framework 中都有相同的文件，但是我该如何解决这个问题呢？

提前致谢。

Answer 1

1.删除（并移至垃圾箱）Fabric.framework 和任何已安装的 Fabric 套件及其相关资源。

1. 在项目中执行清理和深度清理 (ALT-SHIFT-CMD-K)

2. 将 Fabric pod 添加到您的 Podfile：pod 'Fabric'

3. 在 Podfile 中为您的项目使用的每个 Fabric 套件添加一个 pod：pod 'Crashlytics'

注意：如果您需要 Crashlytics 和 Answers，您应该只安装 pod 'Crashlytics'，因为 Answers 包含在 Crashlytics 中。如果您想要没有 Crashlytics 的 Answers，请仅安装 pod 'Answers'。

希望能解决您的问题。如果所有失败尝试删除所有 pod 并按该顺序再次添加它们。 祝你好运！
