Jazzy OSX 10.11.3 Xcode 7.2.1发行查找XCRUN

Question

对于下面的命令行，Jazzy有以下问题。检查过命令行工具等，看上去都不错。

$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
$ whereis xcrun
/usr/bin/xcrun

shell命令/脚本

Answer 1

看来这就是问题所在。>1版本的xcode已安装。XCODE / PREFERENES / LOCATIONS /命令行工具。选择合适的工具，即使在安装了新版本的工具后，也是空白的。

Answer 2

在我的例子中，发生这种情况并不是因为我没有为Xcode指定位置，而是因为我使用的是Xcode 8。

这是一种奇怪的行为，因为在我的例子中，/usr/bin/xcrun是存在的，但它没有包含在/Applications/Xcode.app/Contents/Developer/usr/bin中。在以前版本的Xcode中，该目录包含xcrun，但在Xcode 8中不包含，至少在我的Mac版本中没有。

我尝试在那里创建一个符号链接，指向/usr/bin/xcrun，但它没有解决问题。

我找到的唯一解决方案是更改触发错误的代码，将/usr/bin/xcrun -find xcrun替换为/usr/bin/xcrun -find xcodebuild。

我认为这是一件非常安全的事情，因为这个命令的目的是检查Xcode是否已正确安装，因此新命令完成了任务。令人放心的是，Qtbase做了什么：https://code.qt.io/cgit/qt/qtbase.git/commit/?h=wip/nacl
