Poetry is extremely slow when resolving the dependencies

See original GitHub issue

I am on the latest Poetry version.
I have searched the issues of this repo and believe that this is not a duplicate.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

OS version and name: Centos 7
Poetry version: 1.0.0

Issue

I created an empty project and run poetry add allennlp. It takes ages to resolve the dependencies.

Yes, i’m running into the same problem. Resolving dependencies takes forever. I tried to use VPN to get through the GFW, nevertheless, it is still not working. I also tried to change pip source and wrote local source in the toml file, neither works. It’s driving me nuts.

First, it’s capitalized PyPI.

Second, there is no way for PyPI to know dependencies for all packages without executing arbitrary code – which is difficult to do safely and expensive (computationally and financially). PyPI is run on donated infrastructure from sponsors, maintained by volunteers and does not have millions of dollars of funding like many other language ecosystems’ package indexes.

For anyone interested in further reading, here’s an article written by a PyPI admin on this topic: https://dustingram.com/articles/2018/03/05/why-pypi-doesnt-know-dependencies/
