Rails 服务器未启动我收到此错误

Question

我无法让我的 Rails 服务器开始搜索几个小时。有人可以帮忙吗？我已经添加了下面的代码

我对此真的很陌生。

ali_bodill_photogrphy.application.configure do
# Settings specified here will take precedence over those in config/application.rb.

# In the development environment your application's code is reloaded on
# every request. This slows down response time but is perfect for development
# since you don't have to restart the web server when you make code changes.
config.cache_classes = false

# Do not eager load code on boot.
config.eager_load = false

# Show full error reports and disable caching.
config.consider_all_requests_local       = true
config.action_controller.perform_caching = false

# Don't care if the mailer can't send.
config.action_mailer.raise_delivery_errors = false

# Print deprecation notices to the Rails logger.
config.active_support.deprecation = :log

# Raise an error on page load if there are pending migrations.

# Debug mode disables concatenation and preprocessing of assets.

# number of complex assets.

既然你是新人，那就说说调试过程

--

错误

此处显示错误（第一行）：

未定义的局部变量或方法`ali_bodill_photogrphy' 主：对象（名称错误）

“计算机”相关问题的基本底线是错误的逻辑原因。开始寻找问题原因的合乎逻辑的地方是确定问题是什么；因此寻找错误信息

在您的情况下，消息说您的line 1 上没有ali_bodill_photography 方法config/environments/development.rb：

ali_bodill_photogrphy.application.configure do

--

修复

这是 Rails 核心的问题。如果你改变了这个文件，你会想把它改回来；或查看其他文件以判断“正确”方法需要是什么。

我会给你一些来自我们的 Rails 4 应用程序的例子：

#config/environments/development.rb (4.1.4)
Rails.application.configure do

#config/environments/development.rb (4.0.0)
Appname::Application.configure do

#config/environments/development.rb (3.2)
AppName::Application.configure do

基于上述文件，我建议查看您的 Rails 版本，并修改 development.rb 文件的顶部以复制上述任一示例

因此，如果您有 Rails 4.1.4（最新），您可以将您的 all_bodill_photograph 替换为 Rails。如果您使用的是较低版本的 Rails，您似乎需要使用应用程序名称的常量化版本 - AppName::Application
