[英]Fedora 24 - Ruby on Rails installation error
我嘗試在新的Fedora 24安裝中安裝滑軌。 我遵循了本教程https://developer.fedoraproject.org/tech/languages/ruby/ror-installation.html 。
但是我得到了這個錯誤:
Building native extensions. This could take a while...
ERROR: Error installing rails:
ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.

To see why this extension failed to compile, please check the mkmf.log which can be found here:
/usr/local/lib64/gems/ruby/nio4r-1.2.1/mkmf.log
extconf failed, exit code 1
Gem files will remain installed in /usr/local/share/gems/gems/nio4r-1.2.1 for inspection.

我用谷歌搜索解決方案,但沒有成功。 你能給我建議嗎? 謝謝
您是否已根據日志中的錯誤消息安裝了“開發工具”?
編譯器無法生成可執行文件。 (RuntimeError)
您必須先安裝開發工具。
sudo dnf group install "C Development Tools and Libraries"
