RVM things I've run into

rvm.md

• SSL issues when installing any gem, either using gem install or bundle install:

  • Replace the certs from rvm osx-ssl-certs with the ones from cURL:

    $ wget 'https://curl.haxx.se/ca/cacert.pem'
    $ cp cacert.pem /usr/local/etc/openssl/cert.pem
    $ sudo cp cacert.pem /etc/openssl/cert.pem
    

• Switching Ruby versions inside a Python virtualenv throws a warning such as:

  Warning! PATH is not properly set up, '/Users/idguser/.rvm/gems/ruby-2.3.1/bin' is not at first place,
          usually this is caused by shell initialization files - check them for 'PATH=...' entries,
          it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
          to fix temporarily in this shell session run: 'rvm use ruby-2.3.1'.
  

  • Add the following to ~/.rvmrc:

    rvm_silence_path_mismatch_check_flag=1
    

• Installing pg or hitimes gems fails with an error such as:

  ld: in '/usr/local/lib/libiconv.2.dylib', file was built for i386 which is not
  the architecture being linked (x86_64): /usr/local/lib/libiconv.2.dylib for
  architecture x86_64
  

  • The pdftk utility includes its own libiconv, which causes some issues. Unlink it while installing the pg gem:

    $ brew unlink pdftk
    $ bundle install  # or:    $ gem install pg
    $ brew link pdftk
