在将swift从版本3.2更新到版本4.0后，迦太基构建失败。
下面是使用carthage update --platform iOS的结果。

Build Failed
Task failed with exit code 65:

This usually indicates that project itself failed to compile. Please check the xcodebuild log for more details: /var/folders/6z/c0myz1fn4rsgy842p9vqqr700000gn/T/carthage-xcodebuild.my2Am1.log
然后
$ tail /var/folders/6z/c0myz1fn4rsgy842p9vqqr700000gn/T/carthage-xcodebuild.my2Am1.log我明白了：

这就是我为解决这个问题所做的。
删除派生迦太基缓存。
删除项目中的迦太基目录。
卸载迦太基并重新安装。
下载Xcode 8.3.2和
xcode-select --switch /Applications/Xcode8.app/Contents/Developer并使用xcrun命令确保版本已更改为swift 3.0，然后更新迦太基。清洁项目和重建
重新启动Xcode
如果有人能帮助我，我将不胜感激。
最佳答案
我正在使用Xcode 8.3.1，这就是我所遵循的：
Deleted derived data.
Removed Carthage folder: rm -r ./Carthage
Updated Cartfile with:
github "facebook/facebook-sdk-swift" "master"
github "facebook/facebook-ios-sdk" "sdk-version-4.21.0"
运行迦太基命令：
carthage update --platform iOS --no-use-binaries
