部署引发错误"不知道如何构建任务'资产:预编译'"(Capistrano)

Question

有人在运行后遇到此错误:

cap production deploy

我正在使用capistrano:Capistrano版本:3.6.1(耙子版本:11.3.0)

这是日志:

(Backtrace restricted to imported tasks)

Answer 1

听起来你可能没有设置Sprockets(一个只有API的应用程序？).

在你的Capfile中,你可能有类似的东西:

require 'capistrano/rails'

该行实际上需要一个看起来像这样的文件:

require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'

所以你可以用以下代替前一行:

require 'capistrano/rails/migrations'

并且将不再运行资产预编译.

如上所述,这假设您实际上并不想使用资产管道.如果不是这种情况,问题是您不包括Sprockets,您需要研究它.我会生成一个新的rails应用程序并比较你的Gemfile和config/application.rb.

Answer 2

如果您的 Rails 应用程序只是 API，请不要添加require 'capistrano/rails/assets'或require "capistrano/rails"。

添加以下内容：

require 'capistrano/bundler'
require 'capistrano/rails/migrations'

最后，您的 Capfile 将如下所示：

require "capistrano/setup"
require "capistrano/deploy"

require "capistrano/scm/git"
install_plugin Capistrano::SCM::Git

require "capistrano/rbenv"
set :rbenv_type, :user
set :rbenv_ruby, "2.5.1"

require 'capistrano/bundler'
require 'capistrano/rails/migrations'

# Load custom tasks from `lib/capistrano/tasks` if you have any defined
Dir.glob("lib/capistrano/tasks/*.rake").each { |r| import r }
