Problèmes avec l'exécution de la bibliothèque sendgrid-ruby en tant que script ruby ​​

Question

J'essaie d'envoyer un email à la bibliothèque sendgrid-ruby, et j'ai réussi à écrire un script que je peux exécuter ligne par ligne et me mettre au travail. Cependant, lorsque je tente d'exécuter le script dans son ensemble, je reçois

/Users/andrewaccuardi/.rvm/gems/ruby-2.4.1/gems/sendgrid-ruby-5.1.0/lib/sendgrid/client.rb:24:in `+': no implicit conversion of nil into String (TypeError)

Voici le code que je me sers de l'appel:

require 'sendgrid-ruby' 
include SendGrid 

sg = SendGrid::API.new(api_key: ENV['SENDGRID_API_KEY']) 
email = SendGrid::Mail.new 
email.from = SendGrid::Email.new(email: "example@email.com", name: "Example User") 
email.subject = "Your Email's Subject" 

p = SendGrid::Personalization.new 
p.add_to(SendGrid::Email.new(email: "example_email", name: "example_name")) 
p.add_substitution(Substitution.new(key: '-companyName-', value: 'Example_company')) 
p.add_substitution(Substitution.new(key: '-eventName-', value: 'DINOSAUR PARTY')) 
p.add_substitution(Substitution.new(key: '-eventDays-', value: '35')) 
p.add_substitution(Substitution.new(key: '-eventStartDate-', value: '08/15/1993')) 
p.add_substitution(Substitution.new(key: '-eventEndDate-', value: '12/22/1992')) 
p.add_substitution(Substitution.new(key: '-eventStartTime-', value: '12:30pm')) 
p.add_substitution(Substitution.new(key: '-eventEndTime-', value: '12:30am')) 
p.add_substitution(Substitution.new(key: '-eventAddress-', value: '1234 SE Main St.')) 
p.add_substitution(Substitution.new(key: '-eventYears-', value: '3')) 
p.add_substitution(Substitution.new(key: '-eventWebsite-', value: 'www.example.com')) 
p.add_substitution(Substitution.new(key: '-eventFacebook-', value: 'facebook.com/example')) 
p.add_substitution(Substitution.new(key: '-eventTwitter-', value: 'twitter.com/example')) 
p.add_substitution(Substitution.new(key: '-eventOtherMedia-', value: 'othermedia.com/example')) 
p.add_substitution(Substitution.new(key: '-eventDescription-', value: "Vape shoreditch fixie man bun vexillologist VHS.

p.add_substitution(Substitution.new(key: '-nonProfPhone-', value: '555-555-3331')) 

email.add_personalization(p) 
email.template_id = "684f302c-5669-4114-a953-c3e15d6de44d" 
response = sg.client.mail._('send').post(request_body: email.to_json) 
puts response.status_code 
puts response.body 
puts response.headers 

Toute idée sur la façon d'avancer serait sois super, merci!

Answer 1

La console Rails charge les variables d'environnement de sorte que lorsque le code est exécuté à partir de là, l'ENV ['SENDGRID_API_KEY'] a une valeur.
Lorsque vous l'exécutez en tant que script sans charger l'environnement, le résultat est nul.
Par la documentation ici:
https://github.com/sendgrid/sendgrid-ruby#setup-environment-variables
Vous devez exporter ceci.
