我正在尝试使用 railstutorial.org 创建一个新的 Rails 项目。但是，当我尝试创建新应用时，出现以下错误：

如何摆脱这个 OpenSSL 错误？我正在使用以下内容：

Rails 3.2.14
ruby 1.9.3p448 (2013-06-27 revision 41675) [x86_64-darwin12.5.0]

rvm 1.22.11 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

添加结果：file /user.rvm/rubies/ruby-1.9.3-p448/lib/ruby/1.9.1/x86_64-darwin12.5.0/digest/md5.bundle /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib 和文件/user.rvm/src/ruby-1.9.3-p194/ext/digest/md5/mkmf.log + /user.rvm/src/ruby-1.9.3-p194/ext/openssl/mkmf.log

嗯，这很有可能是矫枉过正，但对我来说，完全卸载 ruby 然后重新安装它，我的项目使用的所有 gem 都解决了这个问题。

如果您使用的是 rbenv，我使用的命令是
rbenv uninstall 2.6.3
rbenv install 2.6.3
gem install bundler
gem install rails -v 6.0.2
rbenv rehash
bundle update

同样，这可能有点矫枉过正，但在brew install openssl 对我不起作用后，它解决了问题。

【解决方案2】：

如果您尚未安装 OpenSSL，请尝试使用 Homebrew 安装它

brew install openssl

【讨论】：

当我尝试得到输出时：警告：openssl-1.0.1e already installed 我很困惑当我创建一个新应用程序时rails如何找不到openssl。
尝试brew reinstall openssl，然后卸载rvm：rvm implode；并重新安装rvm。不过，您可能会继续使用 Chruby，因为它更易于开发。
这个版本的 rvm 确保安装了 openssl 并使用它编译了 ruby，切换到其他工具不会让它神奇地工作，编译期间发生冲突或编译 ruby 后发生了一些变化。
可能发生了许多事情，从 rvm 困难，到拙劣的自制软件安装，再到您的环境同时安装了自制软件和 macport 或其他 OpenSSL 安装。重新安装 OpenSSL 和 Ruby 应该会有所帮助 :) 这解决了您的问题吗？如果是，你能选择一个答案吗？
