capistrano3 - bundle exec rake assets :precompile 没有匹配的主机

Question

我正在使用 capistrano 3.0.1 和 capistrano-rails 1.1.0 进行部署。到目前为止，部署运行良好，只有 assets:precompile 没有被执行。该阶段每次都会跳过此消息:

WARN [SKIPPING] No Matching Host for /usr/bin/env if test ! -d /var/www/versioneye/releases/20140111161403; then echo "Directory does not exist '/var/www/versioneye/releases/20140111161403'" 1>&2; false; fi
 WARN [SKIPPING] No Matching Host for bundle exec rake assets:precompile

 WARN [SKIPPING] No Matching Host for /usr/bin/env find public/images public/javascripts public/stylesheets -exec touch -t 201401111614.03 {} ';'; true

我在 config/deploy/stagging 中只定义了 1 个角色。

role :app, %w{cap@aws-7}

在 config/deploy.rb 中，我将asset_roles 设置为:

set :assets_roles, [:app]   # Defaults to [:web]

知道为什么 assets:precompile 没有被执行吗？

Answer 1

没有匹配的主机可能意味着您没有为该角色设置主机。我也是走捷径，只填了role:app，出现了这个问题，填了role:web，还是有问题，填了 >role :db，我可以成功部署，包括每次写入crontab。

role :app %w{cap@aws-7}
role :web %w{cap@aws-7}
role :db  %w{cap@aws-7}

其中 cap@aws-7 是您的 deployuser@hostname.com
