LoadError: 无法加载此类文件 -- config/deploy

Question

Ubuntu 20.04、Ruby 3.0.1、rails 6.1.3.1、Capistrano 版本：3.16.0（Rake 版本：13.0.3）

运行任何“cap”命令会导致以下结果，例如：-

>> bundle exec cap install --trace
(in /)
cap aborted!
LoadError: cannot load such file -- config/deploy
Did you mean?  rbconfig/sizeof

我尝试创建新的 Rails 应用程序，但出现了同样的错误。

尝试了许多不同的方法（降级 ruby​​、rails 等），结果相同。我认为这可能是一个权限问题，感谢您提供任何帮助。

更新 #2

是的，在应用程序的根目录中运行命令。

参见下面的代码 sn-ps。

~/WebProjects/test_site$ ls -1
app
bin
config
config.ru
db
Gemfile
Gemfile.lock
lib
log
package.json
public
Rakefile
README.md
storage
test
tmp
vendor

~/WebProjects/test_site$ bundle exec cap install

(produces the error output in the question above)

感觉很简单，但我就是想不通（经过几个小时的挠头！）。

更新 #3

~/WebProjects/test_site$ cat /Capfile
load 'deploy' if respond_to?(:namespace) # cap2 differentiator
Dir['vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }

load 'config/deploy' # remove this line to skip loading any of the default tasks

Answer 1

Capfile 位于导致问题的 Ubuntu 根目录 (/) 中。
