Hi all, I am a total newbie in both ruby and rails development. I have problem with libyaml (apparently). I had rvm installed and did: rvm install 1.9.3. Installation of ruby was completed successfully however it complained about libyaml (below): Fetching yaml-0.1.4.tar.gz to /Users/pouya314/.rvm/archives Extracting yaml-0.1.4.tar.gz to /Users/pouya314/.rvm/src Error running ''tar mzxf /Users/pouya314/.rvm/archives/ yaml-0.1.4.tar.gz -C /Users/pouya314/.rvm/src '', please read /Users/ pouya314/.rvm/log/yaml/extract.log Configuring yaml in /Users/pouya314/.rvm/src/yaml-0.1.4. Error running '' ./configure --prefix="/Users/pouya314/.rvm/usr" '', please read /Users/pouya314/.rvm/log/yaml/configure.log Compiling yaml in /Users/pouya314/.rvm/src/yaml-0.1.4. Error running ''make '', please read /Users/pouya314/.rvm/log/yaml/ make.log I ignored the error at the time and went on to install rails but i got the following warning: It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your ruby. --- I''m on os x lion. xcode version = 4.3 rvm version = 1.10.2 Please reply if you know how to solve this issue.
