【求助】centos 上 gem install 显示成功，但 gem list 没有相关包

new_rubyer — Sun, 04 Sep 2022 02:00:29 +0800

我的 ruby 项目需要一些三方库，如 oj、recog 等。我使用 gem install 安装了对应包，显示成功，但是运行项目时依旧提示缺少相关包，gem llist 也没有找到。搜索寻找后发现 gem install 的包在 - "gem" => "--install-dir=/opt/rh/rh-ruby30/root/usr/local/share/gems --bindir /opt/rh/rh-ruby30/root/usr/local/bin" ，即/opt/rh...目录下。我是希望能将三方包导入到/usr/local/lib/ruby/gems/3.0.0/gems 的目录下的。我应该怎么做呢？或者可以改变 ruby 项目引用的三方库的路径吗？改成/opt/rh...? 我之前安装 ruby 遇到了麻烦，rbenv，yum install rh-ruby30 都做了尝试，最后选择了下载 gz 文件自己解压编译，之前的 yum 包我已经 remove 了，这会有影响吗？恳求大家帮忙，配了好几天，快失去信心了...... 以下是 gem env
