構建 gem 原生擴展失敗？

Question

我最近嘗試通過運行gem install rails 。 但是，它總是失敗並顯示以下錯誤消息。

Temporarily enhancing PATH for MSYS/MINGW...
Building native extensions. This could take a while...
ERROR:  Error installing rails:
        ERROR: Failed to build gem native extension.

有誰知道這里實際發生了什么？ 我會很感激任何答案。 謝謝

Answer 1

通常，編譯 gem 擴展時出現的“多目標模式”錯誤是由安裝 Ruby 或 gem 的目錄名稱中的空格引起的。

特別是在 Windows 上，您應該將 Ruby 安裝到不包含空格的目錄，而不是當前位置D:/Program Files/Ruby30-x64 。 要解決此問題，我建議卸載 Ruby 並再次將其安裝到更合適的位置。
