Question

我最近尝试通过运行 gem install rails 通过 gem 安装 rails。但是，它总是失败并显示以下错误消息。

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

有人知道这里实际发生了什么吗？我将不胜感激任何答案。谢谢

通常，编译 gem 扩展时的这种“多目标模式”错误是由安装 Ruby 或 gem 的目录名称中的空格引起的。

特别是在 Windows 上，您应该将 Ruby 安装到不包含空格的目录，而不是您当前的位置 D:/Program Files/Ruby30-x64。要解决此问题，我建议您卸载 Ruby 并将其重新安装到更合适的位置。

无法构建 gem 本机扩展？
