尝试推送最新的 Ensembles podspec 时出现链接失败。规范没有改变，但 Cocoapods 更新到了 0.39.0。Xcode 无疑也发生了变化，这可能是罪魁祸首，但我无法解释错误。

 -> Ensembles (1.4.3)
- ERROR | [Ensembles/Dropbox] xcodebuild: Returned an unsuccessful exit code.

我不确定链接故障是否导致其他错误，或者 lipo 错误导致链接故障。我找不到有关链接器退出失败的更多信息。

任何人都知道可能导致这种情况的原因，以及可能的解决方案是什么？

更新

我确实设法找到了我认为的根本错误：

看起来 Cocoapods 正在尝试创建一个动态库，但不知何故，这不适用于 iPhone 模拟器架构的旧 Dropbox 库。任何人都知道这方面的变化，也许是一种防止 Cocoapods 使用动态库的方法？

我发现了问题： Cocoapods 似乎默认开始构建动态框架而不是静态库。显然链接到我正在使用的旧 Dropbox pod 是一个问题。

要改为使用静态库，您只需传递--use-libraries给您正在运行的pod trunk pushorpod lib lint命令。

pod lib lint命令将检查*.podspec文件中的选项。在我的情况下，问题显示如下：

->  MySDK git:(master) ✗ pod lib lint --allow-warnings
 -> MySDK (0.0.1)
    - WARN  | description: The description is shorter than the summary.
    - ERROR | [OSX] xcodebuild: Returned an unsuccessful exit code. You can use `--verbose` for more information.
    - NOTE  | [OSX] xcodebuild:  clang: error: linker command failed with exit code 1 (use -v to see invocation)

该[OSX]标志显示该pod lib lint命令尝试根据您的*.podspec文件构建项目，但是在 OSX 平台中构建项目时发生了错误。

我的解决方案是s.platform = :ios, "5.0"在 podspec 文件中添加。

之后，运行pod lib lint一切正常。
