NoMethodError: undefined method `URI' for #<Acme::Client:0x0056023f1c6c80>

Following the README produces something like below on my machine. Strange.

require 'uri' is missing?

[Charles Barbier]

You are right, uri is not explicitly require.

Its working for me locally using ruby 2.4.4p296

$ irb                    
irb(main):001:0> require 'acme-client'
=> true
irb(main):002:0> private_key = OpenSSL::PKey::RSA.new(4096)
=> #<OpenSSL::PKey::RSA:0x00007ff44d139f90>

Probably because a version of my dependency must requiring it. I will add an explicit require for this.

Just out of curiosity, what version of Faraday are you using?

[Onno]

Faraday? I don't know? What is Faraday? Am I using it?

[Charles Barbier]

It should be in the constant Faraday::VERSION
