部署引发错误 "Don't know how to build task 'assets:precompile'" (Capistrano)

Question

在运行之后有没有人遇到过这个错误：

cap production deploy

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

这是日志：

(Backtrace restricted to imported tasks)

Answer 1

听起来您可能没有设置 Sprockets（仅 API 应用程序？）。

在你的 Capfile 中，你可能有这样的东西：

require 'capistrano/rails'

那一行实际上 requires a file 看起来像：

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

因此您可以将前一行替换为：

require 'capistrano/rails/migrations'

并且资产预编译将不再是运行。

如上所述，这假定您实际上不想使用资产管道。如果不是这种情况，问题是您没有包括 Sprockets，您需要对此进行调查。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 rails 申请只有 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'

最后你的 Capfile 看起来像这样：

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 }
