让sendgrid-ruby库作为ruby脚本运行的问题

Question

我正试图让sendgrid-ruby库发送一封电子邮件，我已经成功地编写了一个脚本，我可以逐行运行并开始工作。但是，当我试图作为一个整体运行脚本时，我会得到

/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)

下面是我用于调用的代码：

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: '-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

任何关于如何前进的洞察力都将是伟大的，谢谢！

Answer 1

Rails控制台加载环境变量，因此在从中执行代码时，ENV‘’SENDGRID_API_KEY‘具有值。

在不加载环境的情况下，将其作为脚本运行时，其结果为零。

以下是每一份文件：

你得出口这个。
