在CircleCI上用Fastlane构建MacOS项目时出现神秘错误。

Question

当我在 circleCI 上使用 FastLane 构建 MacOS 项目时，遇到了以下错误。我可以在本地使用 bundle exec fastlane test因此，这个问题似乎与CircleCI环境有关，但我不知道如何追踪它。当我ssh进入CircleCI时，我能够在命令行上重现它。

以下是错误信息。

我的Fastfile是这样的

default_platform :mac

platform :mac do
  before_all do
    setup_circle_ci
  end

  desc "Runs all the tests"
  lane :test do
    scan(skip_testing: "ChronosUITests")
  end

  desc "Ad-hoc build"
  lane :adhoc do
    match(type: "adhoc")
    gym(export_method: "ad-hoc")
  end
end
