我正在尝试在Rails 4中运行一个简单的bundle exec rake db:seed命令以填充我的数据库。但是,在运行时,我得到以下输出:
********-C02MGBVJFD57:myapp ***********$ bundle exec rake db:seed
Your Gemfile lists the gem factory_girl_rails (>= 0) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of just one of them later.
rake aborted!

这是我的seeds.rb文件:
User.create!(
name: "Example User",
email: "example@railstutorial.org",
password: "foobar",
password_confirmation: "foobar",
admin: true
)
99.times do |n|
name = Faker::Name.name
email = "example-#{n+1}@railstutorial.org"
password = "password"
User.create!(
name: name,
email: email,
password: password,
password_confirmation: password
)
end
第16行是:
name = Faker::Name.name
有什么想法,为什么我会收到这个错误?谢谢。
rake db:seed
- ptdrake db:seed
在development
环境中运行。如果你在种子文件中使用Faker
,请确保它同时在development
和test
组中。 - jerhinesmith
