Question

我想安装gems simple_xlsx_writer和fast_xs。但是我得到了两个宝石相同的下面的错误。即使对于simple_xlsx_writer。

Building native extensions. This could take a while... 
ERROR: Error installing simple_xlsx_writer: 
       ERROR: Failed to build gem native extension.

*** extconf.rb failed *** 
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. 

Provided configuration options:

Gem files will remain installed in D:/Users/pavana.prasad/.gem/New Folder/gems/fast_xs-0.8.0 for inspection.

请帮我安装宝石。

假设您使用了RubyInstaller，您还需要DevKit来使用C扩展构建宝石。 simple_xlsx gem取决于fast_xs，它使用C扩展名。
