无法安装 cmake - 无法构建 gem 本机扩展

Question

我正在尝试安装cmake和rugged宝石。我的Ruby是193，我的DevKit是对应这个版本安装的。我修改了系统PATH并安装了DevKit。

现在我尝试运行gem install cmake，但出现错误：

> gem install cmake
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing cmake:
        ERROR: Failed to build gem native extension.

        C:/Ruby193/bin/ruby.exe extconf.rb
*** 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:
        --with-opt-dir
        --without-opt-dir

        --without-opt-include=${opt-dir}/include
        --with-opt-lib
        --without-opt-lib=${opt-dir}/lib

我不知道该怎么办，我之前使用过较新的 Ruby，问题是一样的。我能做些什么？

Answer 1

我通过下载安装程序来安装它，然后通过 UI 安装。出于我的目的，我需要确保选中将变量添加到我的 PATH 中的框。
