升级swift后蒸汽工具箱坏了

升级到Swift 3.1后尝试使用Vapor工具箱时崩溃了.

Swift ABI还不稳定.因此,必须重新编译Swift程序(如Vapor ToolBox)以使用该语言的新版本.

使用Brew重新安装

只需重新安装工具箱即可解决此问题.

brew reinstall vapor/tap/vapor

用Brew替换旧安装

如果最初未使用Homebrew安装,则可能需要删除现有的可执行文件

rm /usr/local/bin/vapor

然后确保可执行文件消失

which vapor

您现在可以使用brew安装

brew install vapor/tap/vapor
