无法在Mojave上安装jazzy

Question

我试着在Mojave测试版上安装jazzy，但是失败了，因为我得到了这个错误

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，是否有其他方法可以在不使用gem的情况下安装jazzy？

或者您可能知道用于swift项目的其他好的文档生成器？

Answer 1

试试这个

sudo gem install -n /usr/local/bin jazzy

Answer 2

xcode-select --install为我做了这件事。

之后，我可以通过[sudo] gem install jazzy安装jazzy

Answer 3

这对我来说很有效，我不知道为什么，但它确实起了作用。我想它是从.pkg手动安装命令行工具的

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