ruby - 更新到 Catalina 后无法安装 Jekyll - 安装 ffi (1.9.18) 时出错

Question

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。

这是我运行通常的 grunt 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.

然后我跑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.

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.

In Gemfile:
  jekyll was resolved to 3.4.3, which depends on
    jekyll-sass-converter was resolved to 1.5.1, which depends on
      sass was resolved to 3.5.5, which depends on

当我跑

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。

当我跑

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

我尝试从另一个帖子运行它，但没有运气 gem install ffi -v '1.9.18' -- --with-cflags="-Wno-error=implicit-function-declaration"

有没有人有任何想法？

谢谢

Answer 1

根本问题是您无法安装 jekyl 的依赖项之一 - 特别是 ffi gem。知道这将更好地帮助您进行修复。

您可以通过阅读您的捆绑输出看到这是错误。学习如何阅读这些内容，以便将来更好地帮助自己；如果您正在搜索“在 macOS 上安装 ffi”，您可能会找到更多可用的信息。

假设您刚刚安装了 Catalina，很可能 GCC 不在您的机器上，或者已经过时，或者没有链接。

尝试运行xcode-select --install以（重新）安装 Xcode 命令行工具。

还 - 停止使用 SUDO

在你的包输出的最顶部是一个警告，你不应该sudo在安装 gems 时使用它。这是一个很好的建议！

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，如果你没有一路走下去，** 至少，停止使用 sudo **
