问题描述
我已更新我的Mac以使用Catalina，但现在尝试安装Jekyll时遇到各种问题。
这是我在运行常见的咕噜声设置时得到的结果：
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
然后我得到了这个：
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.

An error occurred while installing ffi (1.9.18), and Bundler cannot continue.
Make sure that `gem install ffi -v '1.9.18' --source 'https://rubygems.org/'` succeeds before bundling.

当我运行时
ruby -v
我得到

我完全不知道我需要做什么。
当我运行时
jekyll -v
我得到
-bash: /usr/local/bin/jekyll: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory
我尝试在另一个帖子上运行这篇文章，但没有成功gem install ffi -v '1.9.18' -- --with-cflags="-Wno-error=implicit-function-declaration"
有人有什么想法吗？
谢谢
推荐答案
根本问题是您无法安装Jekyl的依赖项之一--特别是the ffi gem。了解这一点将更好地帮助您解决问题。
通过阅读包输出，您可以看到这就是错误。了解如何阅读这些内容，以便将来可以更好地帮助自己；如果您正在搜索MacOS上的&Install FFI，您可能会have found more information available to you。
假设您刚刚安装了Catalina，GCC很可能不在您的计算机上，或已过时，或已断开链接。
尝试运行xcode-select --install以(重新)安装Xcode命令行工具。
也-停止使用sudo
在包输出的最顶端有一条警告，提示您在安装gem时不应使用sudo。这是一个值得遵循的好建议！更好的建议是使用rbenv或rvm为您正在使用的每个Ruby应用程序创建gem集或环境。但是，如果你没有沿着这条路走下去，**至少，停止使用sudo** 这篇关于更新到Catalina后无法安装Jekyll-安装ffi时出错(1.9.18)的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
