pip-pop's Issues

python deploy ModuleNotFoundError

I found one problem with pop-diff

the code:
def diff(r1, r2, include_fresh=False, include_stale=False, excludes=None):
include_versions = True if include_stale else False
excludes = excludes if len(excludes) else []

in python 2.7.1.4
if excludes=None
then len(excludes) is error

Isn't a init.py always in need?

i am a beginner of python,and i found that many python projects contains init.py at most time, but some projects not, why?

Support for pip 10

Pip 10 no longer supports the use of internal APIs: https://groups.google.com/forum/#!topic/pypa-dev/JVTfS6ZdAuM.

This causes pip-grep and pip-diff to error with:

File "pip-grep", line 12, in <module>
       from pip.req import parse_requirements
   ImportError: No module named 'pip.req'

Add a Travis config that tests against multiple pip versions

To avoid surprise breakage, it would be great to run a couple of rudimentary tests against different versions of pip.

I'll try to open a PR when I get a moment.

add ability to ignore certian packages

usecase: uninstallation of setuptools

Figure out allow_external bug

File "/app/.heroku/python/lib/python2.7/site-packages/pip-1.5.6-py2.7.egg/pip/req.py", line 1605, in parse_requirements
    finder.allow_external |= set([normalize_name(line).lower()])
AttributeError: 'NoneType' object has no attribute 'allow_external'

pip 8 introduces a new feature that allows people to bake hashes into their requirements.txt, unfortunately this breaks pip-diff. An example would be https://github.com/pypa/warehouse/blob/master/requirements/main.txt

Output looks like:

Traceback (most recent call last):

Need a little adjustment to support new version of pip

from pip._internal.req import parse_requirements
from pip._internal.index import PackageFinder

Broken with recent versions of pip

pip changed the signature of parse_requirements to require a session keyword argument as of version 6. Should be able to pass in whatever session is required for forward and backward compat. I'll submit a PR when I get time if you've not gotten to it by then.

Question about pip-grep

If the parameters contain multiple packages, such as "pip-grep tests/test-requirements.txt requests django", and the "test-requirements.txt" include these two packages too. But the program only print the first package. Is it normal?
Thanks.

Add support for pip 8.x

Currently with pip 8.1.2, the following exception is raised:

$ ./pip-grep foo.txt requests
Traceback (most recent call last):
  File "./pip-grep", line 81, in <module>
    main()
  File "./pip-grep", line 76, in main
    grep(**kwargs)
  File "./pip-grep", line 57, in grep
    if requirement.req.project_name in packages:
AttributeError: 'Requirement' object has no attribute 'project_name'

This is caused by pypa/pip#3307 , which changed the type of req, such that it now has a name attribute rather than project_name.

To avoid surprises with new versions of pip, and to prevent regressions with older versions when making compatibility fixes, I've filed #9.

ImportError: No module named _vendor.requests

stone@mint ~/git/pip-pop/bin $ ./pip-diff
Traceback (most recent call last):
File "./pip-diff", line 17, in
from pip._vendor.requests import session
ImportError: No module named _vendor.requests

Do I need to install some modules?
