Cocoapods 0.39.0推送podspec时链接器错误

Question

当试图推动最新的集群podspec时，链接出现故障。规范不变，但Cocoapods被更新为0.39.0。毫无疑问，Xcode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.
- NOTE  | [Ensembles/Dropbox] xcodebuild:  clang: error: linker command failed with exit code 1 (use -v to see invocation)

我不确定是链接失败导致了其他错误，还是lipo错误导致了链接失败。我找不到更多关于链接器退出故障的信息。

有谁知道是什么原因造成的，以及解决办法是什么？

更新

我确实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，但这在某种程度上不适用于iPhone模拟器体系结构中的旧Dropbox库。有人知道这方面的变化，也许是防止Cocoapods使用动态库的一种方法吗？

Answer 1

我发现了问题: Cocoapods似乎已经开始构建动态框架，而不是默认的静态库。显然，连接到我正在使用的旧Dropbox吊舱是一个问题。

要使用静态库，只需将--use-libraries传递给正在运行的pod trunk push或pod lib lint命令。

Answer 2

pod lib lint命令将检查*.podspec文件中的选项。就我而言，问题表现如下：

->  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)

[OSX]标志显示pod lib lint命令试图根据您的*.podspec文件构建一个项目，但是当在OSX中构建项目时，发生了一些错误。

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

在那之后，运行pod lib lint，一切都没问题。
