thanks for your reply.

i can open cdn.cocoapod.org in web browser, and ping is ok.

my problem is the "REST" variable can not work.

Yes the original problem here is not about reaching CDN its about REST missing.

@jiamuc can you gem install nap and try again?

Also please use https://bundler.io/ with a Gemfile to ensure all gems are installed and bundled.

thanks for your help, after i installed "nap" , it works.
maybe the issue can be closed.
thanks again.

I get the same problem if I want to install "sqflite" and "path_provider" for flutter project and run it on IOS Device or IOS Simulator. I try 'gem install nap' with bundler.io (Gemfile) but it didn’t help me. :(
