Ruby on rails 如果我在本地安装，Byebug Gem不会拾取

我已经从github下载了

byebug

和

columnize

请有人帮帮我，Byebug附带了一个C扩展，这是它工作所必需的

我想说的是，

bundle安装--local

不编译本地扩展，所以需要手动完成。转到

byebug

的目录，运行

bundle
bundle exec rake compile

然后重试。

您检查过该文件夹的权限了吗？是的，我已通过eBug和columnize文件夹授予了读写权限。是否有机会进行另一次捆绑包更新？

bundle
bundle exec rake compile
