没有路线匹配[GET]＆＃34; /packs/application.js" Rails 5.1

Question

在Rails 5.1上运行集成规范时，javascript_pack_tag帮助程序为public/packs/application.js

中的已编译包/ application.js文件生成路径

但是，bin/rails assets:precompile将使用生产配置编译您的包，其中包括摘要。因此无法找到该文件。

Answer 1

要将包/ application.js编译为public/packs/application.js，请通过以下方式指定开发环境：

RAILS_ENV=development bin/webpack

在运行集成规范之前运行此任务。

Answer 2

这是我在使用Rails 5.1 webpacker gem时在本地测试环境中运行webpack-dev-server的设置：

在config/environments/test.rb中，添加：

unless ENV['CI'] == 'true'
  config.x.webpacker[:dev_server_host] = "http://localhost:8080"
end

然后在spec/rails_helper.rb或您的测试设置中添加：

config.add_setting :webpack_dev_server_pid

config.before(:suite) do
  unless ENV['CI'] == 'true'
    RSpec.configuration.webpack_dev_server_pid = fork do
      puts "Child process starting webpack-dev-server"
      webpack_dev_server_cmd = [
        "#{Rails.root}/node_modules/.bin/webpack-dev-server",
        "--config #{Rails.root}/config/webpack/development.js",
        "--content-base #{Rails.root}/public/packs",
        "--quiet"
      ].join(" ")
      exec(webpack_dev_server_cmd)
    end
  end
end

config.after(:suite) do
  unless ENV['CI'] == 'true'
    puts "Killing webpack-dev-server"
    Process.kill("HUP",RSpec.configuration.webpack_dev_server_pid)
    begin
      Timeout.timeout(2) do
        Process.wait(RSpec.configuration.webpack_dev_server_pid,0)
      end
    rescue => Timeout::Error
      Process.kill(9,RSpec.configuration.webpack_dev_server_pid)
    ensure
      RSpec.configuration.webpack_dev_server_pid = nil
    end
  end
end

此设置允许您在持续集成环境中设置CI=true以禁用webpack-dev服务器，您可以在执行测试套件之前运行RAILS_ENV=development bin/webpack。

这是我支持所有Rails 5.1更新的本地构建命令列表：

brew update 
brew install yarn 
./bin/yarn install 
./bin/yarn add webpack 
./bin/webpack-watcher 
bundle exec rake db:create 
bundle exec rake db:migrate
