LoadError: dlopen(digest/sha1.bundle): Symbol not found: _rb_Digest_SHA1_Finish
Possible solutions:
$ unset C_INCLUDE_PATHand reinstall RubyThis is the solution that worked for me.
$ echo $C_INCLUDE_PATHIf
C_INCLUDE_PATHis set, it will break Ruby builds. Remove it from your environment; either temporarily with$ unset C_INCLUDE_PATH, or permanently (might be in .bashrc, .profile, .bash_profile); then reinstall ruby.It might be related to OpenSSL, RVM, XCode's Command Line Tools (gcc), or other build issues.
See this answer if the previous solution didn't work.
For anyone, like me, coming here because of an error like this:
LoadError: dlopen(/Users/sebkomianos/.rbenv/versions/2.0.0-p247/lib/ruby/2.0.0/x86_64-darwin13.0.0/openssl.bundle, 9): Symbol not found: _SSLv2_client_methodReferenced from: /Users/sebkomianos/.rbenv/versions/2.0.0-p247/lib/ruby/2.0.0/x86_64-darwin13.0.0/openssl.bundleExpected in: /usr/local/opt/openssl/lib/libssl.1.0.0.dylibOne solution (taken from here) might be to reinstall your version of ruby. eg: rbenv install 2.0.0-p247
