Rails 6 Capistrano 部署失败，即使应用程序在手动启动时工作正常
Rails 6 Capistrano deploy is failing even though application works fine when it is started manually
因此，当我将此应用程序部署到 Heroku 时，它可以正常工作
我正在尝试将其部署到 VM（数字海洋上的普通 ubuntu 液滴）
已按预期设置 Capistrano。
我无法弄清楚这个错误可能来自哪里
SSHKit::Runner::ExecuteError: Exception while executing as deploy@<IP ADDRRESS>: rake exit status: 1
rake stdout: Nothing written
rake stderr: Nothing written
Capistrano部署日志如下：

这非常好用。

需要一些帮助
这是我的 deploy.rb:
# config valid for current version and patch releases of Capistrano
lock "~> 3.14.1"
set :application, "mark_antony"
set :repo_url, "git@gitlab.com:browneinstitute/mark.git"
# Default branch is :master
set :deploy_to, "/home/deploy/#{fetch :application}"
append :linked_dirs, 'log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', '.bundle', 'public/system', 'public/uploads'
set :keep_releases, 5
append :linked_files, "config/master.key"
旁注：我手动创建了一个新的 current 符号链接到以这种方式创建的发布目录，以查看 nginx 是否能够为该网页提供服务。
它能够
也许您需要重新添加 ssh，试试这个
ssh-add，然后在您的控制台中再次尝试部署。
问题似乎是您 deploy.rb 中缺少一些关键配置，否则您将无法连接到 Droplet。
# config valid for current version and patch releases of Capistrano
lock "~> 3.14.1"
server 'YOUR_DROPLET_IP',
roles: [:web, :app, :db],
set :user, 'deploy'
set :application, "mark_antony"
set :repo_url, "git@gitlab.com:browneinstitute/mark.git"
# Default branch is :master
set :deploy_to, "/home/deploy/#{fetch :application}"
append :linked_dirs, 'log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', '.bundle', 'public/system', 'public/uploads'
set :keep_releases, 5
# This might not be needed. If needed make sure to provide the correct path to your ssh key
set :ssh_options, {
forward_agent: true,
user: fetch(:user),
keys: %w(~/.ssh/id_rsa)
}
append :linked_files, "config/master.key"
所以我认为这在预编译资产上总是失败，答案在这里：
帮助解决了这个问题，除了我必须为路径添加一个稍微不同的值

set :default_env, {
