Which components shall be installed? If unsure press ENTER [1,2,3] 3
MSYS2 seems to be already installed

解决方法
显然ridk install仅安装MSYS2 https://www.msys2.org/。他们切换了包装维护人员，因此密钥不正确：https://www.msys2.org/news/#2020-06-29-new-packagers。 Pacman是他们的包管理器（例如apt-get，yum，gem）。我有一个旧版本，或者我的旧Ruby 2.4正在安装一个旧版本（版本：“ 20161025”）。我碰巧有Chocolatey，有一个msys2包，所以我用
choco upgrade msys2 # this installed it. i did not have it installed via chocolatey
ridk version # still showed an old version and would not work
pacman -U xz # xz is like gzip - this gave the errors above
choco uninstall msys2 # this didn't do much
del \msys2 # have to manually delete the directory
choco upgrade msys2 # this installed a recent version
ridk install # have to install the make and c++ tools,so include choice 3
它安装了49个软件包，现在make可以正常工作。
