I haven't changed anything (that I'm aware of) in my ruby since when it did work. Any suggestions on where to look?

Answer 1

well looks like you have no sources. see in gem env "gem" => "--no-document"

try running this:

gem sources -a https://rubygems.org/

my env differs by:

- GEM CONFIGURATION:
     - :update_sources => true
     - :verbose => true
     - :backtrace => false
     - :bulk_threshold => 1000
     - :sources => ["https://rubygems.org/"]
     - "benchmark" => false
     - "gem" => "--no-rdoc --no-ri"

can you paste output of ~/.gemrc to make sure? Mine looks like:

---
:backtrace: false
:bulk_threshold: 1000
:sources:
- https://rubygems.org/
:update_sources: true
:verbose: true
benchmark: false
gem: "--no-rdoc --no-ri"

If this doesn't work, perhaps try installing ruby using rvm https://rvm.io/rvm/install
