创建新的 Rails 项目时出现 OpenSSL 错误

Question

I'm trying to create a new Rails project using the railstutorial.org. However, when I try to create a new app, I get the following error:

User-MacBook-Air:rails_projects user$ rails new first_ap

How do I get rid of this OpenSSL error? I am using the following:

Rails 3.2.14
ruby 1.9.3p448 (2013-06-27 revision 41675) [x86_64-darwin12.5.0]

rvm 1.22.11 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

Answer 1

Well, there's a very large chance it was overkill but for me uninstalling ruby entirely and then reinstalling it and all the gems that my project uses solved the problem.

If you're using rbenv, the commands that I used were
rbenv uninstall 2.6.3
rbenv install 2.6.3
gem install bundler
gem install rails -v 6.0.2
rbenv rehash
bundle update

Again, this is probably overkill, but it solved the problem after brew install openssl didn't work for me.

Answer 2

If you haven't installed OpenSSL, try installing it with Homebrew

brew install openssl
