Question

我收到以下错误，不知道如何解决这个问题。有人可以简化这个过程吗？

我的Jruby已安装在

中

C：/jruby-1.7.13/bin

我的项目在

C：/用户/ MYNAME /下载/ projectdirectory

错误就在我做的时候

bundle install

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

c:/jruby-1.7.13/bin/jruby.exe extconf.rb
  NotImplementedError: C extension support is not enabled. Pass -Xcext.enabled=true to JRuby or set JRUBY_OPTS.

     Make sure that `gem install pg -v '0.17.0'` succeeds before bundling.

在JRuby中实际上不支持C扩展，并且实际上已经在1.7.x行中删除了......

因此尽管提到-Xcext.enabled=true的消息不会帮助你！

因为您正在尝试 pg ，所以使用Java API而不是C pg_jruby 的jruby替代方案，或者如果您正在使用活动记录查找 activerecord-jdbc-adapter + jdbc-postgres

如何在Jruby中启用C扩展错误？
