Crystal: dockerhub crystallang/crystal:0.19.2 does not ship with yaml

[grosser]

error while loading shared libraries: libyaml-0.so.2: cannot open shared object file: No such file or directory

is this by design ? ... can we have a nicer error message then ?
... if it's not by design ... any idea how to fix ?

Maybe docker images should come with everything the standard library uses...

[grosser]

sounds reasonable to me ...

Hello,

This has been solved by #3441:

$ docker run -it crystallang/crystal bash

root@a873bceeab61:/opt/crystal# crystal --version
Crystal 0.20.3 [b1416e2] (2016-12-23)

root@a873bceeab61:/opt/crystal# cd /tmp/

root@a873bceeab61:/tmp# cat test.cr 
require "yaml"

puts YAML.dump({:foo => 10})

root@a873bceeab61:/tmp# crystal build test.cr

root@a873bceeab61:/tmp# ./test
