MSYS2 installation failure: 'MSYS2 seems to be unavailable'

[ahirschberg]

What problems are you experiencing?

I'm running into an issue with the MSYS2 installer, running on a Windows .NET Core (v4.6) box, where the installation will not begin/complete

Steps to reproduce

Download the latest ruby 2.4 via chocolatey
Execute C:\tools\ruby24\ridk.cmd or ridk.ps1
Press 1 to perform base MSYS2 installation
Observe output MSYS2 seems to be unavailable and Installation failed: MSYS2 installer failed

Output from ridk version and ridk install:

C:\tools\ruby24>C:\tools\ruby24\bin\ridk.cmd version
---
ruby:
  path: C:/tools/ruby24
  version: 2.4.1
  platform: x64-mingw32
ruby_installer:
  package_version: 2.4.1-2
  git_commit: a2667ee

Output of ridk install:

C:\tools\ruby24>C:\tools\ruby24\bin\ridk.cmd 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] 1

MSYS2 seems to be unavailable
Verify integrity of msys2-x86_64-20161025.exe ... OK
Run the MSYS2 installer ...

 Failed
Installation failed: MSYS2 installer failed

The install is failing, so I can't resolve gem dependencies relying on them. For example, libyajl2:

C:\tools\ruby24\alex>..\bin\gem install libyajl2
MSYS2 could not be found. Please run 'ridk install'
or download and install MSYS2 manually from https://msys2.github.io/

You can download the MSYS2 tar file from http://repo.msys2.org/distrib/x86_64/ , extract it on c:/msys64/ and run ridk install afterwards.

Alternatively you could use the unofficial "rubybundle" installer, which installs MSYS2 inside the ruby directory: https://ci.appveyor.com/project/larskanis/rubyinstaller2-hbuor/build/job/qmnwg9008xf53m8i/artifacts

I'll think about using the tar file for ridk install in the future.

Any success with using RubyInstaller on Windows .NET core?

msys2.org seems to be down/unavailable.

[larskanis]

There is proper support for installation of ruby and MSYS2 in chocolatey now: https://chocolatey.org/packages/msys2

I'm on Windows 7 x64.
It seems that MSYS2 has to be install C:\msys64. If installed elsewhere, MSYS2 cannot be detected by ``ridk install''.

If this is true, I suggest adding a description regarding MSYS2 installation directory somewhere.

You can update the default path in /ruby_installer/runtime/msys2_installation.rb. I had the same issue with ridk install not detecting a scoop installed msys2.
