从导轨上拆下链轮

Question

如何从 Rails 上移除链轮？

我有..

• 移除了所有链轮宝石。
• config.assets.*从初始值设定项等中删除所有。

尽管如此，Rails 仍在寻找链轮

/Users/username/.rvm/rubies/ruby-2.5.0/lib/ruby/gems/2.5.0/gems/sprockets-rails-3.2.1/lib/sprockets/railtie.rb:105:in block in <class:Railtie>': Expected to find a manifest file in `app/assets/config/manifest.js (Sprockets::Railtie::ManifestNeededError)

......

 Example:
13:58:38 web.1  |   //= link_tree ../images
13:58:38 web.1  |   //= link_directory ../javascripts .js
13:58:38 web.1  |   //= link_directory ../stylesheets .css

你实际上是如何移除链轮的？

Answer 1

要从 Rails 项目中完全删除链轮：

消除：

# Use SCSS for stylesheets
gem 'sass-rails', '>= 6'

从Gemfile然后运行bundle install.

代替：

require 'rails/all'

和：

require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
require "active_record/railtie"
require "active_storage/engine"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_mailbox/engine"
require "action_text/engine"
require "action_view/railtie"
require "action_cable/engine"
# require "sprockets/railtie"
require "rails/test_unit/railtie"

在config/application.rb文件中。

消除：

# Debug mode disables concatenation and preprocessing of assets.
# This option may cause significant delays in view rendering with a large
# number of complex assets.
config.assets.debug = true

# Suppress logger output for asset requests.
config.assets.quiet = true

来自config/environments/development.rb文件。

消除：

# Compress CSS using a preprocessor.
# config.assets.css_compressor = :sass

# Do not fallback to assets pipeline if a precompiled asset is missed.
config.assets.compile = false

来自config/environments/production.rb文件。

删除 config/initializers/assets.rb文件。

您也可以删除app/assets文件夹，但这不是必需的，因为如果您改变主意，以后可能需要它。
