可以使用pip搜索PyPI软件包，但无法安装。 easy_install工作正常

Question

I'm running into an issue where I execute pip install python-sdk-auth , and I get this error:

Could not find a version that satisfies the requirement python-sdk-auth (from versions: ) No matching distribution found for python-sdk-auth

This package was initially built by running:

python setup.py bdist_egg --exclude-source-files

to only contain .pyc files and uploaded via this twine :

twine upload dist/<packagename>.egg

Here are more observations:

1. I'm able to pip search python-sdk-auth and the package seems to be present in the package directory.
2. I'm able to do easy_install python-sdk-auth , and the package will be installed successfully.
3. I'm running python v2.7.

It seems like I could do this via easy_install , but not on pip . My main intention is to have this package be a dependency of another package (as specified via the install_requires parameter in setup.py , but it seems like even installing this via pip install in a virtualenv environment throws an error above. Any suggestions on what went wrong here? Thanks!

Answer 1

The only distribution for the package available on PyPI is an egg, an older format that is used by setuptools (and thus easy_install ) but not pip. Pip can only install packages from source distributions made with sdist (which every package should have) and from wheels (the replacement for the egg format, which should be preferred to eggs 99.9999% of the time). Build & upload one (or, better, both) of these files to PyPI to make your package installable via pip.
