Hello Can zc.buildout use same comparison operator for versions as setup.py?
*buildout* It use "show-picked-versions" for print verison https://pypi.python.org/pypi/zc.buildout/2.3.1#easier-reporting-and-managing...
[versions] buildout-versions = 1.2 setuptools = 0.6c11 zc.buildout = 1.5.0
*setup.py* It use install_requires for handle package's version https://docs.python.org/2/distutils/setupscript.html#relationships-between-d...
install_requires=[ 'django == 1.4', 'South == 0.7.5', ]
Is there any way for "show-picked-versions" print version be used by setup.py install_requires?

zc.buildout uses a configparser/ConfigParser-based config file, which mandates the single equal sign. It also doesn't support ranges or other (new) PEP 440 syntax for versions ('~=', etc.).

It may be worth noting the intent of specifying versions in a buildout config and a version constraint for a software package in setup.py is different.
Constraints in setup.py are intended to specify what versions a package is compatible with; they're about the code in the package. Versions in a buildout config (sometimes called "nails") are about getting a repeatable build: *this* build should use exactly *this* version.
I hope that helps.

No. They do technically allow limited ranges, but the primary purpose is to set/pin/nail specific versions. Fred did a good job of explaining this.

Why do you ask?

If you run buildout in verbose mode (-v), it will will give an indication of why it's trying to get a particular requirement. Note that requirements can come from a variety of places, including setup.py, the versions section, and requirements stated in egg and similar parts.
