:和这个Capfile
:
require "capistrano/setup"
require "capistrano/deploy"
require "capistrano/rails"
require "capistrano/rbenv"
require "capistrano/bundler"
require "capistrano/scm/git"

install_plugin Capistrano::SCM::Git
set :rbenv_type, :user
set :rbenv_ruby, "2.7.1"
Dir.glob("lib/capistrano/tasks/*.rake").each { |r| import r }
I thought it was spring, then bootsnap, then my environment, but I have the exact same capistrano config on other projects and they work fine.我以为是春天,然后是 bootsnap,然后是我的环境,但我在其他项目上有完全相同的 capistrano 配置,并且它们工作正常。
i think i will also post an issue to the capistrano3-puma repository我想我也会向 capistrano3-puma 存储库发布一个问题
The solution was to lock the version of capistrano3-puma
to 4.0.0
:解决方案是将capistrano3-puma
的版本锁定到4.0.0
:
gem "capistrano3-puma", "4.0.0"
because i was using puma 5 and the most recent version of capistrano3-puma was 1.2.1因为我使用的是 puma 5 而最新版本的 capistrano3-puma 是 1.2.1
see this diff:看到这个差异:
- capistrano3-puma (1.2.1)
- capistrano (~> 3.0)
- puma (>= 2.6)
+ capistrano3-puma (4.0.0)
+ capistrano (~> 3.7)
+ capistrano-bundler
+ puma (~> 4.0)
I had the same issue.我遇到过同样的问题。 This was because, by mistake, I had installed capistrano-puma
.这是因为我错误地安装了capistrano-puma
。
To fix the issue:要解决此问题:
sudo gem uninstall capistrano-puma
