使用 Xcode 8.2 从命令行构建时这是一个错误吗？
我在尝试构建时看到了这个fbsimctl：
brew tap facebook/fb
brew install fbsimctl --HEAD
==> Installing fbsimctl from facebook/fb
==> Cloning https://github.com/facebook/FBSimulatorControl.git
Updating /Users/lnatan/Library/Caches/Homebrew/fbsimctl--git
==> Checking out branch master

If reporting this issue please do so at (not Homebrew/brew or Homebrew/core):

尝试手动构建而不是使用脚本，我遇到了类似的问题：

有趣的是，从 Xcode 构建成功。
