Question

所以我正在学习本教程：https://meta.discourse.org/t/beginners-guide-to-install-discourse-on-macos-for-development/15772 但是当我使用 bundle install 时它给了我这个错误：

An error occurred while installing openssl (2.2.0), and Bundler cannot
continue.
Make sure that `gem install openssl -v '2.2.0' --source 'https://rubygems.org/'`
succeeds before bundling.

但是为什么我会得到这个？

再说一遍，为什么会发生这种情况？请帮忙！ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

openssl gem 基本上是一组围绕 openssl 库的包装器。在构建本机扩展步骤期间，bundler 无法在您的系统中找到该库。因此 gem 无法安装。

这很奇怪，因为您显式链接的脚本在捆绑 gems 之前很久就安装了 openssl

<块引用>

log_info "Upgrading and linking OpenSSL ..."
  brew install openssl
  brew link openssl --force

检查脚本的输出是否有错误（并检查它是否已经到了这一步）。您可能会在那里找到缺少 openssl 库的原因（或者只是尝试使用上述命令手动安装 openssl）。

安装 openssl 库后，使用命令检查其版本

openssl version -a

如果您安装了自定义的 openssl 库，那么遵循错误消息中的建议并手动安装 openssl gem 可能会有所帮助，同时指定 openssl 库的路径
