安装nokogiri 1.6.8.1失败（Ruby 2.7.8 + Ubuntu + rbenv）

在Ubuntu系统上用rbenv管理Ruby 2.7.8运行应用，执行bundle install时遇到错误：

安装nokogiri (1.6.8.1)时出错，Bundler无法继续。请确保gem install nokogiri -v '1.6.8.1' --source 'https://rubygems.org/'执行成功后再进行打包。

尝试过以下所有安装nokogiri的方法，但均失败：

gem install nokogiri -v '1.6.8.1' --source 'https://rubygems.org/'
gem install nokogiri -v '1.6.8.1' --source 'https://rubygems.org/' -- --use-system-libraries
gem install nokogiri -v '1.6.8.1' -- --use-system-libraries --with-xml2-include=/usr/include/libxml2
先执行bundle config build.nokogiri --use-system-libraries再执行bundle install

安装过程中出现的错误（截取部分内容）：
