capistrano error: no such file to load — openssl (Ruby on Rails)

While setting up capistrano as suggested in Agile Development with Rails (2nd edition), you may run into the following error:
no such file to load — openssl

The full context of the error is below:

$ rake remote:setup
(in [deployment directory])
Capistrano/Rake integration is deprecated.
Please invoke the ‘cap’ command directly: `cap setup’
* executing task setup
* executing “mkdir -p -m 775 [deployment directory] [deployment directory]/releases [deployment directory]/shared [deployment directory]/shared/system &&\n mkdir -p -m 777 [deployment directory]shared/log &&\n mkdir -p -m 777 [deployment directory]/shared/pids”
servers: [“hostname”]
rake aborted!
no such file to load — openssl

On Ubuntu 6.06 (LTS) this means that the openssl ruby interface is missing, and that it needs to be installed:

$ sudo apt-get install libopenssl-ruby1.8

From the apt-cache description: libopenssl-ruby1.8 – OpenSSL interface for Ruby 1.8

  1. Thanks for the post. Only thing that took me a little while to get was that I didn’t have universe repositories enabled. Once I figured that out this fixed the error.

    The same error occurred when I was trying to run rake test for actionpack (I was about to submit a doc patch for Rails source code).

    Thanks :)

    Hello
    I had the same problem, but I was using CentOS. I installed ruby from scratch, not from a repository. After googling a while I found that extensions must be compiled one by one. In my case, I had to compile openssl and zlib. Steps:
    1. Go to $RUBY_INSTALLER_DIR/ext/
    2. Type “ruby extconf.rb”
    3. make & make install

    Thanks a ton!!!

    I really require this solution….:)

    thanks for the help !

  10. For me this meant “install the libssl-dev package then recompile ruby” (or, if you don’t have time, just touch openssl.rb in your pwd)

  11. drp

    even four years later it still works …

    thx so much :)


    Ubuntu 10.4
    ruby 1.8/1.9
    capistrano 2.5.5

  12. For me on Ubuntu 10.10, rvm, ruby 1.8.7, rubygems 1.4.2 for the same openssl error but not for capistrano, I was required to install libssl-dev

    Thanks for the hint @roger!
