我正在尝试安装 gems simple_xlsx_writer 和 fast_xs。但是对于两个宝石，我都得到了相同的以下错误。即使对于 simple_xlsx_writer。

Building native extensions.  This could take a while...
ERROR:  Error installing simple_xlsx_writer:

Could not create Makefile due to some reason, probably lack of

                --ruby=C:/Program Files/Ruby187/bin/ruby


Gem files will remain installed in D:/Users/pavana.prasad/.gem/New Folder/gems/fast_xs-0.8.0 for inspection.
Results logged to D:/Users/pavana.prasad/.gem/New Folder/gems/fast_xs-0.8.0/ext/fast_xs/gem_make.ou

请帮我安装gem。

假设您使用 RubyInstaller，您还需要 DevKit 来构建带有 C 扩展的 gem。simple_xlsx gem 依赖于 fast_xs，它使用 C 扩展。
