Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.

关于为什么将 Devise gem 正确添加到 Gemfile 并运行捆绑安装后无法安装的任何想法?
我确实在某个时间点运行了服务器(rails 服务器),并看到一篇文章指出尝试在服务器启动时安装 Devise 可能会导致奇怪的问题。
此后我再次尝试关闭服务器,但没有任何区别。我确定这可能是因为我在设置中忽略了一些非常简单的事情,只是不确定还有什么地方可以看。
任何关于下一步看哪里的建议或建议都会很棒,谢谢。
我已经使用以下命令完成了测试,但仍然收到相同的错误:
leigh@leigh-VirtualBox:~/Projects/dev01$ bundle exec rails g devise:install
Could not find generator devise:install.
已安装的生成器列表如下,而 Devise 未列出,我如何将其列出?
leigh@leigh-VirtualBox:~/Projects/dev01$ rails generate
Usage: rails generate GENERATOR [args] [options]
General options:
-h, [--help] # Print generator's options and usage
-p, [--pretend] # Run but do not make any changes
-f, [--force] # Overwrite files that already exist
-s, [--skip] # Skip files that already exist
-q, [--quiet] # Suppress status output
Please choose a generator below.
Rails:
assets
controller
generator
helper
integration_test
jbuilder
mailer
migration
model
resource
scaffold
scaffold_controller
task
Coffee:
coffee:assets
Jquery:
jquery:install
Js:
js:assets
TestUnit:
test_unit:generator
test_unit:plugin

【问题讨论】:
-
如果您输入
rails generate,您会在任何地方看到设计选项吗? -
您使用的是 RVM 还是任何其他版本管理器。您可能将 Devise gem 安装在与您预期不同的 gemset 上。
-
不,运行 rails generate 没有列出设计
-
我正在使用 rbenv 进行版本控制/管理。
