阅读更多关于 Faulty ruby compilation with rvm: getting 'undefined symbol: rb_Digest_MD5_Init' while running racku

问题 I am on Ubuntu. Any ideas? Do I have to set any compilation option? 回答1: It seems you're missing some devel packages on your system. See my article here, specifically this step. I'm not sure, but the MD5 code could be part of libssl, so it would be covered by installing these packages. $ sudo apt-get install zlib1g-dev libreadline5-dev libssl-dev libxml2-dev 来源： https://stackoverflow.com/questions/3545118/faulty-ruby-compilation-with-rvm-getting-undefined-symbol-rb-digest-md5-init
