列出python包依赖项而不加载它们?
问题描述
说python包A需要B、C和D；有没有办法列出 A →B C D 不加载它们?
元数据中的 Requires (yolk -M A) 通常不完整，grr.
可以下载A.tar/A.egg，然后查看A/setup.py，但其中一些非常血腥.
Say that python package A requires B, C and D;
is there a way to list A → B C D without loading them ?
Requires in the metadata (yolk -M A) are often incomplete, grr.
One can download A.tar / A.egg, then look through A/setup.py,
but some of those are pretty gory.
(我认为至少获得第一级依赖项可以机械化；即使是 98% 的解决方案也比雪崩式下载要好.)
(I'd have thought that getting at least first-level dependencies could be mechanized; even a 98 % solution would be better than avalanching downloads.)

解决方案
Snakefood
sfood -fuq package.py | sfood-target-files
将列出依赖项.
`-f` tells sfood to follow dependencies recursively
`-u` tells sfood to ignore unused imports
`-q` tells sfood to be quiet about debugging information
要从标准库中过滤掉模块，您可以使用
To filter out modules from the standard library, you could use
sfood -fuq package.py | sfood-filter-stdlib | sfood-target-files
正如您已经注意到的，如果您想忽略其他目录，您也可以使用 sfood -I 标志.
As you've already noted, if there are other directories you'd like ignored, you can also use the sfood -I flag.
