我正在使用 Capistrano v2.13.4 进行部署。

之前的 Capistrano 任务 ( deploy:special_treats)deploy:finalize_update未执行。

该任务deploy:special_treats为 做一些准备（设置互联网访问）bundle:install，否则bundle:install将无法访问互联网 ([out :: servername] Could not reach https://rubygems.org/

在config/deploy.rb

before 'deploy:finalize_update', 'deploy:special_treats'

和

namespace :deploy do
  task :special_treats do
    run "echo 'something special treats: setup the Internet access'"
  end
end

结果为cap deploy:update

我只是遇到了同样的问题，但在after deploy:finalize_update触发器中。不同的是我的脚本在另一台机器上工作了很长时间。

我没有将 capistrano 锁定为 中的 gem Gemfile，所以我尝试恢复到相同版本的工作机器，2.6.0但这并没有解决它。

经过一些研究和几次试验，我在 github 项目中发现了一些问题，导致了这种情况，但看起来人们无法完全重现它。

然后我前往文档并浏览我发现 Capistrano 的行为受到了0.9.x与命名空间冲突有关的 rake 版本的最新更改的影响，正如您在部署时可以找到的简短注释中看到的那样：Capistrano 任务 wiki 页面的 create_symlink 部分

我没有时间修复脚本以使用 rake 和 capistrano 的最新版本，但通过将 rake 恢复为 version ，我能够让它在另一台机器上重新工作0.8.7。

我希望这可以让您继续前进并为解决方案提供一些线索。
