[Nix-dev] gem nix writes sha256 = "no hash"

[Bjørn Forsman]

Hi,

When I run "gem nix --nix-file
pkgs/development/interpreters/ruby/generated.nix", several packages
get a "no hash" sha256 sum (literally!). Does anyone know why this
happens and what we can do about it?

-    multi_json_1_7_7 = {
+    multi_json_1_7_8 = {
       basename = ''multi_json'';
       meta = {
         description = ''A common interface to multiple JSON libraries.'';
         homepage = ''http://github.com/intridea/multi_json'';
         longDescription = ''A common interface to multiple JSON
libraries, including Oj, Yajl, the JSON gem (with C-extensions), the
pure-Ruby JSON gem, NSJSONSerialization, gson.rb, JrJackson, and
OkJson.'';
       };
-      name = ''multi_json-1.7.7'';
+      name = ''multi_json-1.7.8'';
       requiredGems = [  ];
-      sha256 = ''1w3fpi52h4a7r0a670xzrwa40l5irh69r45cbvxw24bsp19sfxzr'';
+      sha256 = ''no hash'';
     };

Best regards,
