问题描述
我已经更新了Mac以使用Catalina，现在尝试安装Jekyll时遇到各种问题。
这是我运行常规的grunt设置时得到的：
Running "jekyll:dist" (jekyll) task
>> Error: Command Failed: bundle exec jekyll -v
>> bundler: command not found: jekyll
>> Install missing gem executables with `bundle install`
Warning: Please install Jekyll before running this task. Use --force to continue.
然后我运行sudo bundle install
然后我得到这个：
Don't run Bundler as root. Bundler can ask for sudo if it is needed,and installing your bundle as root will break this
application for all non-root users on this machine.

我跑步时
ruby -v
我明白了
ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19]
我根本不知道我需要做什么。
我跑步时
jekyll -v
我明白了
-bash: /usr/local/bin/jekyll: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory
我尝试从另一篇文章中运行它，但是没有运气
gem install ffi -v '1.9.18' -- --with-cflags="-Wno-error=implicit-function-declaration"
有人有什么想法吗？
谢谢
解决方法
根本问题是，您无法安装jekyl的依赖关系之一-特别是the ffi gem。知道这一点将更好地帮助您进行锻炼。
通过阅读包输出，您可以看到这是错误。学习如何阅读这些内容，以便将来更好地帮助自己；如果要搜索“在macOS上安装ffi”，则可能会have found more information available to you。
鉴于您刚刚安装了Catalina，GCC可能不在您的计算机上，或者已经过时，或者未链接。
尝试运行xcode-select --install以（重新）安装Xcode命令行工具。
也-停止使用SUDO
在软件包输出的最上方是一个警告，警告您在安装gem时不应该使用sudo。遵循它是一个很好的建议！
甚至更好的建议是使用rbenv或rvm为正在使用的每个红宝石应用程序创建宝石集或环境。但是，如果您不走这条路，至少**，请停止使用sudo **
