"Search for package" during poetry init does not work behind a corporate proxy

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

• OS version and name: Ubuntu 18.04.1 LTS
• Poetry version: 0.12.3
• Link of a Gist with the contents of your pyproject.toml file: n/a poetry init fails without generating pyproject.toml file

Issue

When running poetry init in an environment behind a corporate proxy, and attempting to interactively resolve dependencies, it times out during the first run of “Search for package” with the following trace

The problem seems to arise in xmlrpclib which doesn’t include built-in support for http or https proxies. https://docs.python.org/2/library/xmlrpclib.html#example-of-client-usage includes an example of how to instruct xmlrpclib to use a proxy. I’m not sure if the same approach will work for xmlrpc.client.

I’m not sure if poetry wants to default to the proxies defined in the users environment variables if they’re set (typically some of http_proxy, https_proxy, no_proxy, HTTP_PROXY, HTTPS_PROXY, NO_PROXY) or to explicitly require a user to pass a proxy arg to poetry. Either one works although using the environment variables if set is what other tools do by default.

Thanks

Current versions of Poetry respect the PROXY_/proxy_ environmental variables in poetry search.

I’m getting the same ImportError and I’m not using any proxy.

Edit: traceback (poetry init -vvv)
