ruby 3.0.4，redmine 5.0.0，rails 6.1.4，测试安装启动 webrick 失败，"wrong number of arguments"

Question

新 ubuntu-20 系统具有以下内容：

  ruby 3.0.4
  rails 6.1.4
  redmine 5.0.0

安装后，尝试启动 webrick 测试服务器：

bundle exec rails server webrick -e redmine_test

失败：

/home/test_user/.gem/ruby/3.0.4/gems/thor-1.2.1/lib/thor/base.rb:525:in `handle_argument_error':
  ERROR: "rails server" was called with arguments ["webrick"] (Thor::InvocationError)

我不清楚它在抱怨哪些参数/语法；我尝试了不同的组合，但都抱怨参数数量错误：

bundle exec rails server webrick -e redmine_test        (given 1, expected 0)
bundle exec rails server webrick -e=redmine_test        (given 1, expected 0)
RAILS_ENV=redmine_test bundle exec rails server webrick (given 1, expected 0)
bundle exec rails server webrick redmine_test           (given 2, expected 0)
bundle exec rails server webrick                        (given 1, expected 0)

Answer 1

command-line 格式似乎已更改 Rails 6:

> rails server --help
Usage:
  rails server -u [thin/puma/webrick] [options]
               ^^

您可能还需要将 webrick 添加到您的 Gemfile 中：

bundle add webrick

ruby 3.0.4，redmine 5.0.0，rails 6.1.4，测试安装启动 webrick 失败，"wrong number of arguments"

ruby 3.0.4, redmine 5.0.0, rails 6.1.4, test install start with webrick fails, "wrong number of arguments"

ruby
