安裝 nokogiri (1.10.10) 時出錯，Bundler 無法繼續

Question

• 操作系統：Ubuntu 18.04
• ruby：2.7
• 導軌：6.*

Gem::Ext::BuildError: 錯誤: 無法構建 gem 原生擴展。

/home/.rvm/rubies/ruby-2.7.0/bin/ruby -I /home/.rvm/rubies/ruby-2.7.0/lib/ruby/2.7.0 -r./siteconf20210329-30335-1ed7nme。 rb extconf.rb --use-system-libraries 檢查 C 編譯器是否接受... *** extconf.rb 失敗 *** 由於某種原因，可能缺少必要的庫和/或頭文件，無法創建 Makefile。 檢查 mkmf.log 文件以獲取更多詳細信息。 您可能需要配置選項。

要查看此擴展無法編譯的原因，請查看 mkmf.log，可在此處找到：

/home/.rvm/gems/ruby-2.7.0/extensions/x86_64-linux/2.7.0/nokogiri-1.10.10/mkmf.log

extconf 失敗，退出代碼 1

Gem 文件將繼續安裝在 /home/.rvm/gems/ruby-2.7.0/gems/nokogiri-1.10.10 以供檢查。 結果記錄到 /home/.rvm/gems/ruby-2.7.0/extensions/x86_64-linux/2.7.0/nokogiri-1.10.10/gem_make.out

安裝 nokogiri (1.10.10) 時出錯，Bundler 無法繼續。 確保gem install nokogiri -v '1.10.10' --source 'https://rubygems.org/'在捆綁之前成功。

Answer 1

首先，檢查您的 mkmf.log 文件以獲取更多詳細信息。

gcc: error: unrecognized command line option '-Wduplicated-cond'
gcc: error: unrecognized command line option '-Wmisleading-indentation'
gcc: error: unrecognized command line option '-Wimplicit-fallthrough=0'

解決方案：brew unlink gcc

$ bundle install （可以正常工作）
