更新到 Catalina 后无法安装 Jekyll - 安装 ffi (1.9.18) 时出错
Cannot install Jekyll after updating to Catalina - An error occurred while installing ffi (1.9.18)
我已经更新了我的 mac 以使用 Catalina，现在我在尝试安装 Jekyll 时遇到了各种各样的问题。
这是我 运行 我通常的 g运行t 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.
我然后运行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.

当我运行
ruby -v
我明白了
ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19]
我完全不知道我需要做什么。
当我运行
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
我从另一个 post 尝试 运行ning 这个但是没有成功
gem install ffi -v '1.9.18' -- --with-cflags="-Wno-error=implicit-function-declaration"
有没有人有什么想法？
谢谢
根本问题是您无法安装 jekyl 的依赖项之一 - 特别是 the ffi gem。知道这一点将更好地帮助您解决问题。
您可以通过阅读您的包输出来了解这是错误。学习如何阅读这些内容，以便您将来可以更好地帮助自己；如果您正在搜索“在 macOS 上安装 ffi”，您可能 have found more information available to you.
鉴于您刚刚安装了 Catalina，GCC 很可能不在您的机器上，或者已过时，或者未链接。
尝试 运行 xcode-select --install（重新）安装 Xcode 命令行工具。
另外 - 停止使用 SUDO
在您的包输出的最顶部是一条警告，提示您在安装 gem 时不应使用 sudo。遵循这个好建议！
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，如果你不一直沿着这条路走下去，**至少，停止使用 sudo**
