Cannot install dependencies from install_requires

Question

I want to have the following dependcies in my setup.py:

setup(
    ...
    install_requires=[

        'pcapy>=0.10.0',
    ],
    ...
)

But pcapy cannot be loaded using tox:

GLOB sdist-make: /home/kartoch/Documents/works/python/scapy/setup.py
py27 create: /home/kartoch/Documents/works/python/scapy/.tox/py27
py27 installdeps: setuptools>=5.4.1, nose>=1.3.0
py27 inst: /home/kartoch/Documents/works/python/scapy/.tox/dist/scapy-2.2.0-dev.zip

Cleaning up...
No distributions at all found for pcapy>=0.10.0 (from scapy==2.2.0-dev)
Storing debug log for failure in /home/kartoch/.pip/pip.log

Whatever is the solution, this is at each time the same problem.

By default, it does not want to load the 0.10.3 version from pypi (see pip log below).

If I use the dependency_links pointing to latest version at github,

setup(
   ...
    install_requires=[
        'pcapy==0.10.8',
    ],
   dependency_links = ['http://github.com/CoreSecurity/pcapy/tarball/master#egg=0.10.8']
   ...
)

The same pip log is returned.

Any idea ?

PS1: PIP is called with the followiçng command by tox

install_command = pip install --allow-external pcapy --allow-unverified pcapy {opts} {packages}

PS2: The PIP log error

Answer 1

using requirements.txt solves the problem:

pycrypto>=2.6.0
