Running ridk install doesn't install msys2

[golyalpha]

What problems are you experiencing?

When installing Ruby 2.5.1 (ruby -v >ruby 2.5.1p57 (2018-03-29 revision 63029) [x64-mingw32]), and running ridk install, the install fails with

MSYS2 could not be found. Please run 'ridk install'
or download and install MSYS2 manually from https://msys2.github.io/

Steps to reproduce

1. Install Ruby 2.5.1
2. run ridk install
3. press enter or type 1 and press enter

What's the output from ridk version?

---
ruby:
  path: C:/Ruby25-x64
  version: 2.5.1
  platform: x64-mingw32
ruby_installer:
  package_version: 2.5.1-1
  git_commit: 71c9f4e
sh: GNU bash, version 4.4.19(2)-release (x86_64-pc-msys)
os: Microsoft Windows [Version 10.0.17134.48]

Current solution is to, of course, install MSYS2 manually, but I feel that that's something ridk install should take care of by itself.

Step 1 should download an run the MSYS2-installer exe file. ridk version shows that you already have a bash installed: sh: GNU bash, version 4.4.19(2)-release (x86_64-pc-msys). Possibly they interfere each other. Can you please post the full output of ridk install?

[golyalpha]

That's because I ran it for this issue after I installed MSYS2

[larskanis]

If you just want a working ruby installation, it's the easiest option, to download the Ruby+Devkit flavor and install it into your current Ruby install directory. This will add a separate MSYS2 directory inside C:/Ruby25-x64.

You could also re-use an already present MSYS2 installation, by using one of the options described in #75 . However in this case you still have to run ridk install 3 at least, in order to get compiler and other required tools on your system.

[golyalpha]

I never had MSYS2 or Ruby on my system. What I had to do is install Ruby and MSYS2 through their installers and then run ridk install to finish MSYS2's setup for Ruby.

[golyalpha]

My point being, ridk install is responsible for (among other things) installing MSYS2, at which it fails.

[larskanis]

What a pity, but again: Can you please post the full output of ridk install?

[golyalpha]

Working on it, just have to uninstall msys2 first.

MSYS2 could not be found. Please run 'ridk install'
or download and install MSYS2 manually from https://msys2.github.io/

Would it be possible that it's conflicting with having WSL installed?

I don't think so. But I found a constellation where I can partly reproduce your error. I'll dig deeper - stay tuned!

[larskanis]

This is a bug introduced two months ago. Thank you for highlithing this!

Can you please change the file

C:\Ruby25-x64\lib\ruby\site_ruby\2.5.0\ruby_installer\runtime\components\01_msys2.rb

Line 11 to

if msys.with_msys_apps_enabled(if_no_msys: :raise) { run_verbose("sh", "-lc", "true") }

and run ridk install again? This should fix the issue.

[golyalpha]

Can confirm successful fix.

[larskanis]

Ok thanks. I'll release 2.5.1-2 and 2.4.4-2 today or tomorrow with this fix included.
