nio4r gem 無法使用本機擴展構建（嘗試安裝 redmine_knowledgebase 插件）

Question

從 Ubuntu 服務器 20.04 上的最后一個 Linux bitnami 安裝程序（4.2）下載並安裝了 Redmine。 安裝沒有問題，redmine 已啟動並正常運行：

  Redmine version                4.2.0.stable
  Ruby version                   2.5.8-p224 (2020-03-31) [x86_64-linux]
  Rails version                  5.2.5
  Environment                    production
  Database adapter               Mysql2

但是，當嘗試安裝知識庫插件時，我使用 nio4r gem 得到編譯器構建錯誤：

bruno@Vostro:~/redmine-4.1.1-8/apps/redmine/htdocs/plugins$ git clone git://github.com/alexbevi/redmine_knowledgebase.git

bundle install --no-deployment

依賴 tzinfo-data (>= 0) 將不會被 Bundler 安裝的任何平台使用。 Bundler 正在為 ruby 安裝，但依賴項僅適用於 x86-mingw32、x64-mingw32、x86-mswin32。 要將這些平台添加到包中，請運行 bundle lock --add-platform x86-mingw32 x64-mingw32 x86-mswin32。 Bundler 安裝的任何平台都不會使用依賴項 ffi (>= 0)。 Bundler 正在為 ruby 安裝，但依賴項僅適用於 x86-mingw32、x64-mingw32、x86-mswin32。 要將這些平台添加到包中，請運行 bundle lock --add-platform x86-mingw32 x64-mingw32 x86-mswin32。

An error occurred while installing nio4r (2.5.7), and Bundler cannot continue.
Make sure that gem install nio4r -v '2.5.7' --source 'https://rubygems.org/' succeeds before bundling.

In Gemfile:
redmine_crm was resolved to 0.0.54, which depends on
rails was resolved to 5.2.5, which depends on
actioncable was resolved to 5.2.5, which depends on nio4r

在捆綁之前嘗試直接安裝 gem nio4r 時，相同的編譯器構建錯誤：

gem install nio4r -v '2.5.7' --source 'https://rubygems.org/'

有什么見解嗎？ 謝謝

在加載 Bitnami 控制台后，我已經能夠使用 Bitnami Redmine 4.1.X（知識庫插件不正式支持 Redmine 4.2）在 Ubuntu 20 的新實例中安裝插件。 您能否按照以下命令嘗試安裝插件：

cd INSTALLDIR
./use_redmine
. ./scripts/setenv.sh
cd apps/redmine/htdocs/
bundle install
bundle exec ./bin/rake redmine:plugins:migrate NAME=redmine_knowledgebase RAILS_ENV=production
INSTALLDIR/ctlscript.sh restart
