无法在Mojave上安装Jazzy

Question

我试图在Mojave beta上安装jazzy，但是失败了，因为我遇到了以下错误

MacBook-Pro-Damian:~ damiandudycz$ sudo gem install jazzy
Password:
Building native extensions.  This could take a while...
ERROR:  Error installing jazzy:

有人能帮我解决这个问题吗？或者有其他方法可以安装 jazzy 而不需要使用 gem 吗？

或者你知道其他适用于 swift 项目的好文档生成器吗？

我正在使用Catalina，这对我也起作用了。感谢您节省了我数小时的时间 :) - Septronic

Answer 2

xcode-select --install 对我很有帮助。
然后我能够通过 [sudo] gem install jazzy 安装jazzy。

Answer 3

这对我有用，但我不知道为什么。我想它是手动从 .pkg 安装了命令行工具。

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
