ruby-on-rails - Nokogiri gem build error failed to build gem native extension on WSL with RVM

Question

我将 WSL (ubuntu) 用于带有 RVM 版本 1.29.12 的 Windows 10。
Ruby 版本是 2.4.1p11。捆绑器版本 1.16.4。
当我执行捆绑安装时，它在 nokogiri 上停止并抛出此错误:

To see why this extension failed to compile, please check the mkmf.log which can be found here:

An error occurred while installing nokogiri (1.8.1), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.8.1' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  view_source_map was resolved to 0.1.4, which depends on
    rails was resolved to 5.1.4, which depends on

            rails-dom-testing was resolved to 2.0.3, which depends on
              nokogiri

我尝试了一些我在网上找到的建议

    gem install pkg-config -v "~> 1.1"

或者

sudo apt-get install libxml2-dev libxslt-dev

但我似乎无法摆脱错误。
我也尝试单独安装 nokogiri 然后再次执行 bundle install 但同样的问题仍然存在。
提前致谢。

尝试这个。这是指示捆绑器寻找库

bundle config build.nokogiri --use-system-libraries
bundle install

如果以上不起作用。检查您的日志文件。在大多数情况下，一些库会丢失。

sudo apt-get install zlib1g-dev
sudo apt-get install libxml2-dev
sudo apt-get install libxslt-dev
