Note: Calls to rubygems.org are deprecated - proceed with caution!
注意：不推荐调用 rubygems.org - 谨慎操作！
I had the same issue on Mac OSX after also building ruby2.1.0p0 from the source. I already had openssl installed. It appears that the reference in gems needed refreshing. I ran:
在从源代码构建 ruby2.1.0p0 之后，我在 Mac OSX 上遇到了同样的问题。我已经安装了openssl。看来 gems 中的引用需要刷新。我跑了：
gem source -r https://rubygems.org/to remove
gem source -r https://rubygems.org/去除
followed by
其次是
gem source -a https://rubygems.org/to read
gem source -a https://rubygems.org/阅读
After this, I was able to run gems install bundlersuccessfully.
在此之后，我能够gems install bundler成功运行。
If you run into further errors, you can try ./configure --with-openssl-dir=/usr/local/sslin your ruby downloaded dir/.
如果遇到更多错误，可以尝试./configure --with-openssl-dir=/usr/local/ssl在 ruby 下载的 dir/.

make sure you have libssl-dev installed:
确保你已经安装了 libssl-dev：
dpkg -s libssl-dev
if not, install it:
如果没有，请安装它：
sudo apt-get -y install libssl-dev

In case someone else has this problem, try reinstalling your Ruby version with openssl included
如果其他人遇到此问题，请尝试重新安装包含 openssl 的 Ruby 版本
brew install openssl
rvm reinstall 2.4.0 --with-openssl-dir=`brew --prefix openssl`
You might already have openssl - so you can ignore the first step. This helped me.
您可能已经拥有 openssl - 因此您可以忽略第一步。这对我有帮助。

I'm leaving this answer for reference to future Googlers:
我将这个答案留给未来的 Google 员工参考：
Type all these commands in your Terminal (OSX) just to be extra sure you've done everything (this is what eventually worked for me)
在您的终端 (OSX) 中键入所有这些命令，以确保您已完成所有操作（这最终对我有用）
rvm get stable
brew update
brew doctor
brew install openssl
rvm install ruby-2.1 (or whatever version)
rvm use (ruby version here) i.e. rvm use ruby-2.1
rvm gemset create NAME i.e. rvm gemset create rails41
gem install rails -v 4.1
Finally...
最后...
As many commenters have pointed out - you need OpenSSL installed before you compile ruby before you install rails (or other gems)
正如许多评论者指出的那样 - 在安装 rails（或其他 gem）之前，您需要先安装 OpenSSL，然后再编译 ruby

You probably built Ruby from source before installing OpenSSL. Make sure you install it and then try reconfiguring and rebuilding Ruby.
您可能在安装 OpenSSL 之前从源代码构建了 Ruby。确保安装它，然后尝试重新配置和重建 Ruby。

for me it was a case of missing dependencies.
对我来说，这是缺少依赖项的情况。
i thoughti had all the dependencies required to install ruby, but i too was getting an openSSL and readline error.
我以为我拥有安装 ruby 所需的所有依赖项，但我也遇到了 openSSL 和 readline 错误。
i attempted to install ruby with RVM without root privileges which failed but gave me a list of missing dependencies. i then installed the dependencies with a package manager. i then re-attempted to install ruby from source from the beginning, and everything worked OK
我试图在没有 root 权限的情况下使用 RVM 安装 ruby，但失败了，但给了我一个缺少依赖项的列表。然后我用包管理器安装了依赖项。然后我重新尝试从一开始就从源代码安装 ruby，一切正常
the dependencies that were missing, for me, were:
对我来说，缺少的依赖项是：
patch libyaml-devel autoconf gcc-c++
readline-devel libffi-devel openssl-devel
automake libtool bison sqlite-devel
but they may be different for you.
但它们对你来说可能不同。
update:i don't originally remember where exactly i found this list, but a quick search found similar lists on the following pages, which might also help you:
