如何在 Python 3.5 (OS X 10.10 Yosemite) 上安装 PyObjC？

Question

我正在尝试使用 pip3 install pyobjc-core 在具有 Python 3.5 和 OS X 10.10.5 (Yosemite) 的 Mac 上安装 PyObjC。我收到以下错误消息：

类似的，如果我只是尝试做 pip3 install pyobjc，我会得到类似的引用，以这些致命的词结尾：

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/v0/bzvt8grs6mv33_j13_wdwqs80000gr/T/pip-build-432fq8a3/pyobjc-core/

对我有什么希望，或者是否存在一些已知的与 Python 系统捆绑版本不兼容的问题？

我在这里晚了一个月，但错误的第一行是：

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

您需要从应用商店安装 xcode 的完整版本，而不仅仅是命令行工具。 :)
