我已经在这里看到了几个(好的,不是那么多,但有几个)问题来处理这个错误,但是没有一个提议的解决方案适合我。这就是我得到的

$ swift

在我发出一些我不记得的命令之后,可能会发生这种情况,也可能不会发生这种情况(而且我的bash历史并没有太大帮助)。奇怪的是,如果我卸载Xcode,REPL开始正常工作。但是,如果我重新安装Xcode,则会出现错误。顺便说一句,我在Xcode 7.2.1(7C1002)上。想法?

要查看当前的Xcode路径:

xcode-select -p

我是一条古老的道路:

/Applications/Xcode.app/Contents/Developer

然后通过以下方式更新此路径:

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