python pip broken after update

Question

I am seeing the following error from pip on several versions of python3 that I am running:

...
    raise MissingSchema('Proxy URLs must have explicit schemes.')
pip._vendor.requests.exceptions.MissingSchema: Proxy URLs must have explicit schemes.

It looks like something with the requests library.

And this is with pip 1.5.2 on python 3.3.4

Answer 1

I'm guessing that the new version is more strict about checking that your proxy settings are valid. If you have an environment variable like http_proxy=localhost:3128 then update it to http_proxy=http://localhost:3128 and you should be fine again. (Ditto for https_proxy -- actually I guess recent versions of pip insist on using HTTPS?)
