Travis-ci 出现问题，无法获取依赖项 Swift Package Manager

Question

我很难让我的项目在 travis 上构建。 它是用 Swift 4 编写的，Travis 应该支持。似乎在获取依赖项时存在问题，但是"它适用于我的机器"。 至少swift build和swift test，所以我很难弄清楚特拉维斯这边的问题可能是什么。

这里有没有人处理过类似的问题并知道出了什么问题？

事实证明，travis 在获取依赖项时失败，当它处于script阶段（在 .yml 中）

解决方案是添加一个install标记，其中获取所有依赖项。

os:
  - osx
language: swift
osx_image: xcode9
install: swift package update
script:
  - swift build
  - swift test
