如何在Ruby 2.7.0上安装Nokogiri

问题描述 投票：1回答：1

我最近升级到Ruby v2.7.0。

[当我尝试安装Nokogiri时，出现以下错误：

ERROR:  Error installing nokogiri:
        The last version of nokogiri (>= 0) to support your Ruby & RubyGems was
1.10.9. Try installing it with `gem install nokogiri -v 1.10.9`
        nokogiri requires Ruby version >= 2.3, < 2.7.dev. The current ruby versi
on is 2.7.0.0.

我尝试使用]安装此gem>

gem install nokogiri -v 1.10.9

但是我遇到了同样的错误。

[我现在使用Ruby v2.7.0时如何安装Nokogiri？我需要安装早期版本的Ruby吗？

gem env的结果是：
