如何比较 Debian 软件包版本? [英] How to compare Debian package versions?

问题描述

我查看了 python-apt 和 python-debian，它们似乎没有比较软件包版本的功能.我必须自己写吗，或者有什么我可以使用的吗?

理想情况下，它看起来像:

<预><代码>>>>v1 = apt.version("1:1.3.10-0.3")>>>v2 = apt.version("1.3.4-1")>>>v1 >v2真的

解决方案

你可以使用 apt_pkg.version_compare:

导入apt_pkgapt_pkg.init_system()a = '1:1.3.10-0.3'b = '1.3.4-1'vc = apt_pkg.version_compare(a,b)如果 vc >0:打印('版本a>版本b')elif vc == 0:print('版本a == 版本b')elif vc <0:print('版本a <版本b')

收益

version a >版本 b

<小时>

感谢 Tshepang 在评论中指出对于较新版本:apt.VersionCompare 现在是 apt_pkg.version_compare.

I looked at python-apt and python-debian, and they don't seem to have functionality to compare package versions. Do I have to write my own, or is there something I can use?

Ideally, it would look something like:

>>> v1 = apt.version("1:1.3.10-0.3")
>>> v2 = apt.version("1.3.4-1")
>>> v1 > v2
True

解决方案

You could use apt_pkg.version_compare:

import apt_pkg
apt_pkg.init_system()

a = '1:1.3.10-0.3'
b = '1.3.4-1'
vc = apt_pkg.version_compare(a,b)
if vc > 0:
    print('version a > version b')
elif vc == 0:
    print('version a == version b')
elif vc < 0:
    print('version a < version b')        

yields

version a > version b

Thanks to Tshepang for noting in the comments that for newer versions: apt.VersionCompare is now apt_pkg.version_compare.
