RIDK 安装：错误：数据库“mingw32”无效（数据库无效或损坏（PGP 签名））

Question

我在尝试安装 MSYS2/MINGW 时收到此错误：

>ridk install
   1 - MSYS2 base installation
   2 - MSYS2 system update
   3 - MSYS2 and MINGW development toolchain

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

MSYS2 seems to be already installed

显然ridk install 只是安装了 MSYS2 https://www.msys2.org/。他们更换了他们的包维护者，所以密钥很糟糕：https://www.msys2.org/news/#2020-06-29-new-packagers。 Pacman 是他们的包管理器（如apt-get、yum、gem）。我要么有旧版本，要么我的旧 Ruby 2.4 正在安装旧版本（版本：'20161025'）。我碰巧有 Chocolatey，有一个 msys2 包，所以我用了

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 个包，现在 make 可以工作了。
