When I was in China, I wanted to change the gem mirror source. At discourse-ai of fork, I modified the gem mirror source information in Gemfile and gemfile. lock, but the log display was still downloaded from https://rubygems.org/. How to make the gem installation in discourse-ai use the gem image source modified in web.china.template.yml
sudo ./launcher rebuild app

Are you in China by any chance?
Yes, is there any solution
I found a solution, the plugin downloaded after the conversion gem image to install the plugin dependent library
- gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/
- su discourse -c 'bundle config mirror.https://rubygems.org https://gems.ruby-china.com/'
- gem install tokenizers -v 0.3.3 -i /var/www/discourse/plugins/discourse-ai/gems/3.2.2 --no-document --ignore-dependencies --no-user-install
- gem install tiktoken_ruby -v 0.0.5 -i /var/www/discourse/plugins/discourse-ai/gems/3.2.2 --no-document --ignore-dependencies --no-user-install
- gem install aws-eventstream -v 1.2.0 -i /var/www/discourse/plugins/discourse-ai/gems/3.2.2 --no-document --ignore-dependencies --no-user-install
It’s best to switch to an overseas server Orz, domestic servers are all inaccessible

If you are in a hurry to build a website, time is more important than money. If you are not in a hurry, you can fiddle with it as you please.
Thanks for the solution. It has been resolved. Adding this to the *.yml configuration also solved the issue of not being able to download related libraries due to the registry.yarnpkg.com website having an invalid SSL certificate.

cd: $home

ruby-china.com isn’t a panacea, and you might encounter other issues later (I did, it seemed like ruby-china.com didn’t update relevant dependencies, which caused problems, but I didn’t take notes on the specific records and can’t recall them clearly).
We’ll cross that bridge when we come to it 
There is indeed a difference between the dependency libraries of accelerated mirror sources and the official version. Switching to an accelerated source, such as USTC, Tsinghua, or Alibaba, Tsinghua has a smaller version difference, and USTC is the fastest. My server is in a private domain, and the public network server only forwards data, resulting in lower overall costs. The server cost is 14 yuan per month, with 2 cores (vCPU), 512 MB RAM, 20GB storage, and 80Mbps/s bandwidth (pay-as-you-go).
Your forum looks good, it seems to be related to medicine. We run a computer technology forum that enables ChatGPT usage in China. We are interested in licensing it to you for use.
