来自TeamCity构建代理的"无法在Simulator中运行应用程序"

我在TeamCity构建代理输出中看到此错误:

...

如果我直接在构建代理程序机器上运行完全相同的命令:

$ /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -project Foobar/Foobar.xcodeproj -scheme foobarNightly SYMROOT=/Users/Me/buildAgent/work/e60c5dca158b2d23/Foobar/build OBJROOT=/Users/Me/buildAgent/work/e60c5dca158b2d23/Foobar/build test -sdk iphonesimulator8.1

有用.知道为什么这个失败来自TeamCity构建代理？
