Rails宝石安装错误- coccon

Question

我在安装柯肯宝石时遇到了这个错误。有人也有同样的问题吗？我使用的是Ruby2.0.0p 353、Rails 4.0和RVM

ERROR:  Error installing cocoon:

Answer 1

茧宝石正在使用珠宝商，它将Rubinius特有的宝石依赖注入宝石规范。从gem规范创建并预期将安装在MRI上的gem包括这些依赖项。我已经提交了一个拉请求来修复这个茧宝石：https://github.com/nathanvda/cocoon/pull/184

通常，我建议在gem的源代码存储库中提交问题，因为作者可能不会被提醒到此处发布的问题。

Answer 2

茧1.2.4有一个破碎的宝石规格，这是固定在1.2.5，并在不久后释放。所以现在就该这么做了。

Answer 3

# cd /path/rubysl-yaml-2.0.4
# vi ext/rubysl/syck/rubyext.c

变更(RSRING -> RSTRING_PTR)

#define syck_copy_string(val) syck_strndup(RSTRING(val)->ptr, RSTRING_LEN(val))

至

#define syck_copy_string(val) syck_strndup(RSTRING_PTR(val)->ptr, RSTRING_LEN(val))

和创业板的构建和安装。

# gem build rubysl-yaml.gemspec && gem install rubysl-yaml-2.0.4.gem

祝好运
