在REPL中创建目标Swift AST上下文时出错：（空）

问题描述

在这里，我已经看到了几个有关解决此错误的问题（不是很多，而是几个），但是没有一个建议的解决方案对我有用。这就是我得到的

I've seen several (well, not that many, but a few) questions here on SO dealing with this error, but none of the proposed solutions worked for me. This is what I get

$ swift
Welcome to Apple Swift version 2.1.1 (swiftlang-700.1.101.15 clang-700.1.81). Type :help for assistance.

此在发出一些我不记得的命令后，可能发生或未发生（我的bash历史记录没有多大帮助）。奇怪的是，如果我卸载Xcode，REPL将开始正常工作。但是，如果我重新安装Xcode，错误会再次出现。顺便说一下，我正在使用Xcode 7.2.1（7C1002）。有想法吗？

This may or may not have happened after I issued some command that I don't remember (and my bash history does not help very much). The odd thing is that if I uninstall Xcode, the REPL starts working correctly. If I re-install Xcode, however, the errors come back. I'm on Xcode 7.2.1 (7C1002), by the way. Thoughts?

推荐答案

查看当前的Xcode路径：

To see your current Xcode path:

xcode-select -p

矿山是一条古老的道路：

Mine was an old path:

/Applications/Xcode.app/Contents/Developer

然后通过以下方式更新此路径：

Then update this path via:

sudo xcode-select -s / Library / Developer / CommandLineTools
