i try to install a package:

$ /home/vagrant/Cloud/git/nimbus-dashboard/.tox/pep8/bin/pip -v install -r Flask
Starting new HTTPS connection (1): pypi.python.org
There was an error checking the latest version of pip

With option --trusted-host it works :

Any idea ?
I'm using pip 6.0.8 on Python 2.6
Thanks

The failed run did -r Flask, the successful one just had Flask (no -r). Isn't that the issue? It's what I'd understand by InstallationError: Could not open requirements file: [Errno 2] No such file or directory: 'Flask'. I'm not sure the SSL error is relevant here.

Sorry for previous log. It's the output :

And it works using :

$ /home/vagrant/Cloud/git/nimbus-dashboard/.tox/pep8/bin/pip -v install Flask --trusted-host pypi.python.org

It looks like there's something wrong with your CA certificates possibly. Do you have a file at /etc/ssl/certs/ca-certificates.crt?

See http://stackoverflow.com/questions/6824332/mercurial-ssh-certificate-issue

I can reproduce this on py 2.6.5 , found while debugging a failure to get-pip.py on Appveyor

https://ci.appveyor.com/project/jayvdb/pywikibot-core/build/1.0.appveyor-more-versions.261/job/y9cd8r87nh23pm6t

It doesnt happen on py 2.6.6 for me.

jayvdb · 2015-06-21T02:13:09Z

Should the docs be updated to say that py 2.6.5 is not supported?

Use --no-clean option to workaround bug in pip. pypa/pip#2494 Fixes ogrisel#15

Use pip --user option to workaround issue during cleanup. pypa/pip#2494 Fixes ogrisel#15

jayvdb · 2016-01-07T03:13:53Z

Either #1087 (wont fix / needs code) or #3336 (PR pending) might provide a workaround for this problem.

asottile · 2016-02-07T18:50:34Z

I'm getting a very similar error under pypy: https://travis-ci.org/pre-commit/pre-commit/jobs/107623837

(In my case, the workaround was to install virtualenv<14 which limits pip to a lower version)

xavfernandez · 2016-02-07T21:51:12Z

It seems it is failing on return self.request('GET', url, **kwargs) what are the used url and kwargs ?

It looks more like a certificate/openssl installation issue than a pip issue...

Cf https://github.com/kennethreitz/requests/issues/557 for possible solutions.

asottile · 2016-02-07T22:29:07Z

My issue seems fixed by pypa/virtualenv#866

xavfernandez · 2016-02-08T09:07:31Z

Great, and the documentation now states that we only support the latest patch version of our supported python versions so closing this.
