Ruby 2.4.10安装Rails依赖及MSYS2开发工具时报错该如何解决？

遇到的问题及背景 #

• 安装Rails项目gems时出现大量make/Makefile相关错误，根源是开发工具未正确安装。
• Ruby Installer with DevKit自带的MSYS2版本存在缺陷，安装部分gems时触发404错误：

  error: failed retrieving file 'mingw-w64-x86_64-binutils-2.30-5-any.pkg.tar.xz' from repo.msys2.org : The requested URL returned error: 404
  

• 为解决上述问题，安装了最新版MSYS2，并重新安装不带MSYS2的Ruby 2.4.10（因不清楚如何修改Ruby Installer中MSYS的默认路径）。
• 运行ridk install并选择选项3时，出现新错误：

  error: target not found: automake1.10
  

解决方法 #

问题出在Ruby Installer默认执行的pacman命令中包含了已从MSYS2仓库移除的老旧包，只需移除这些不存在的包即可修复。

Ruby Installer 2.4.10 with DevKit默认执行的命令 #

pacman -S --needed --noconfirm autoconf autoconf2.13 autogen automake-wrapper automake1.10 automake1.11 automake1.12 automake1.13 automake1.14 automake1.15 automake1.6 automake1.7 automake1.8 automake1.9 diffutils file gawk grep libtool m4 make patch pkg-config sed texinfo texinfo-tex wget mingw-w64-x86_64-binutils mingw-w64-x86_64-crt-git mingw-w64-x86_64-gcc mingw-w64-x86_64-gcc-libs mingw-w64-x86_64-headers-git mingw-w64-x86_64-libmangle-git mingw-w64-x86_64-libwinpthread-git mingw-w64-x86_64-make mingw-w64-x86_64-pkg-config mingw-w64-x86_64-tools-git mingw-w64-x86_64-winpthreads-git

修复后的执行命令 #

移除了automake1.10、automake1.6、automake1.7、automake1.8、automake1.9这些已废弃的包，执行以下命令：

ridk exec pacman -S --needed --noconfirm autoconf autoconf2.13 autogen automake-wrapper automake1.11 automake1.12 automake1.13 automake1.14 automake1.15 diffutils file gawk grep libtool m4 make patch pkg-config sed texinfo texinfo-tex wget mingw-w64-x86_64-binutils mingw-w64-x86_64-crt-git mingw-w64-x86_64-gcc mingw-w64-x86_64-gcc-libs mingw-w64-x86_64-headers-git mingw-w64-x86_64-libmangle-git mingw-w64-x86_64-libwinpthread-git mingw-w64-x86_64-make mingw-w64-x86_64-pkg-config mingw-w64-x86_64-tools-git mingw-w64-x86_64-winpthreads-git
