Installing ruby-2.1.2: Cannot load such file -- openssl (LoadError)

Getting few errors while installing ruby-2.1.2 using rvm. I am new to ruby and hence need assistance. Please let me know

From the log provided in problem description, I have ruby 2.1.2 installed in the system. However, getting error when tried listing gems with `gem list` due to installation errors.After changing to 2.1.2 i.e., `rvm use 2.1.2` and executing `ruby -r openssl -e 'puts OpensSSL::OPENSSL_VERSION'` gives this error:

>/Users/praveenk.k/.rvm/rubies/ruby-2.1.2/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:54:in require': cannot load such file -- openssl (LoadError) from /Users/praveenk.k/.rvm/rubies/ruby-2.1.2/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:54:in require'

On Mac OS X Big Sur, to install Ruby 2.3.2 with RVM, the fix was

brew install rbenv/tap/[email protected]
CFLAGS="-Wno-error=implicit-function-declaration" rvm reinstall ruby-2.2.5 --with-openssl-dir='/usr/local/opt/[email protected]'

On mac BigSur, I fixed it via
```
$ rvm pkg install openssl
$ rvm install 2.1.2 -C --with-openssl-dir=$HOME/.rvm/usr

```
or you can also try with

```
$ rvm pkg install openssl
$ CFLAGS="-Wno-error=implicit-function-declaration" rvm install 2.1.2 -C --with-openssl-dir=$HOME/.rvm/usr

```

For me solve this in centos 7

$ openssl version -a

paste the path in the bellow line how --with-openssl-dir param

$ RUBY_CONFIGURE_OPTS="--with-openssl-dir=/etc/pki/tls" rbenv install 2.7.2

On Amazon Linux 2, even if openssl is installed, you need the full dev kit

```
yum install openssl-devel
```

For debian 10 :

sudo apt-get install -y libssl-dev

Worked example

brew install rbenv/tap/[email protected]
rvm install 2.1.2 -C --with-openssl-dir=`brew --prefix [email protected]`

Ruby <2.4 is incompatible with OpenSSL 1.1 (e.g see

).

Just a hunch, but if you're using Mac + Homebrew, OpenSSL 1.0 was recently deleted, so anything along the lines of `brew upgrade openssl` would trash that.

There are several options to deal with this:

1. I have older Rubies via `asdf` installed with LibreSSL (which may be safer anyway, see

):
```
$ openssl
OpenSSL> version
LibreSSL 2.8.3
```
2. Compile and link your own OpenSSL 1.0 (or then set compiler flags as environment variables when building Ruby --

)
3. See if your system's package manager allows you to access openssl 1.0 and install with that (was helping a coworker with this recently and we weren't able to find a good keg for homebrew at this time, unfortunately)

There might be something less convoluted than that; if someone has ideas, please feel free to comment or give an alternate answer.

**EDIT**

I personally ran into this issue with some other software and discovered that this fixed it, since the old SSL version was sitting around still:
```
brew switch openssl 1.0.2s
```
Should work so long as Homebrew doesn't "helpfully" clean that out for me.
