Installing older version

[sposs]

Hi,
When trying to install a package that has an older version then the oldest in the repository, it doesn't work:

pip install "celery==3.0.25"

Collecting celery==3.0.25
  Could not find a version that satisfies the requirement celery==3.0.25 (from versions: 3.1.4, 3.1.5, 3.1.6, 3.1.7, 3.1.8, 3.1.9, 3.1.10, 3.1.11, 3.1.12, 3.1.13, 3.1.14, 3.1.15, 3.1.16, 3.1.17)
  No distributions matching the version for celery==3.0.25

Installing an older version should work, I just tested it on my machine. I guess you are having some other problem.

Could you provide more detailed steps on how to reproduce this error?

Thanks,

I was trying to install sentry, and it couldn't find celery&lt3.1.0,&gt3.0.5 so I tried to install celery==3.0.25 (the latest version that matches the query). In my localshop, I do not have such a low version, it starts at 3.1.4. The full log I have is (I'm using virtualenvwrapper to get a virtualenv):

mylocalshop is the host name I configured in my .pip/pip.conf.

And I should mention I updated localshop last week.

I think I've managed to reproduce your problem.

The get_package_data function is called every time a package data needs to be fetched from PyPI. It's works but it's very slow. My guess is that the function took a very long time to return and this caused pip to retry the connection. Leaving a bogus packed behind.

Improving the get_package_data performance was already in my TO-DO list. Now that you have found this problem, I moved it to my top priority. I will work on this tonight.

[sposs]

Neat! Thanks!

I have this problem in reverse, when i try to install a newer package (that isn't in my localshop) it fails to install or update the index.

Do you think that's the same problem? a timeout on the get_package_data function?

Also having problems installing newer versions via localshop.

However it seems that this might not be localshops fault. The xmlrpclib package_releases() serves stale data for me.

$ pip install -U django==1.7.6
Collecting django==1.7.6
  No distributions matching the version for django==1.7.6

If I check manually on a different computer then I also do not see version 1.7.6 in the result of the package_releases call:

Sorry for the delay 😞

I latest version on the develop branch is not using the XMLRPC API anymore. I think this should many problems that you might be having.

Could you please retest it? If everything is okay I will release a new version on PyPI.

Thanks,

I am closing this for now. Feel free to reopen if you are still having problems.
