我在本地开发环境中尝试安装 newrelic。以下是我尝试过的 gem 版本列表：
- newrelic_rpm-8.1.0
- newrelic_rpm-8.4.0
- newrelic_rpm-8.8.0
- newrelic_rpm-8.12.0
- newrelic_rpm-8.13.0
- newrelic_rpm-8.13.1
- newrelic_rpm-8.14.0
- newrelic_rpm-8.15.0
- newrelic_rpm-9.0.0
- newrelic_rpm-9.2.2
使用 d/rails s 安装 gem 后，会返回类似以下的错误：
/home/discourse/.bundle/gems/ruby/3.2.0/gems/newrelic_rpm-9.0.0/lib/new_relic/agent/transaction/datastore_segment.rb:34:in `set_instance_info': **stack level too deep (****SystemStackError****)**

或者对于旧版本（<=8）的错误是这样的：
