列出python包依赖关系而不加载它们？ [英] list python package dependencies without loading them?

问题描述

说蟒蛇包A需要B，C和D;
有一种方法来列出A→ BCD没有加载它们？

要求元数据中的（ yolk -MA ）通常不完整，grr。

可以下载A.tar / A.egg，然后查看A / setup.py，
，但其中一些是相当的gory。

（我认为至少获得一级依赖可以机械化;
甚至98％的解决方案将比雪崩下载更好。）

相关问题：
pip-upgrade-package - 没有升级依赖

解决方案

Snakefood

  sfood -fuq package.py | sfood-target-files 
  

将列出依赖项。

 `-f`告诉sfood递归地遵循依赖关系
`-u`告诉sfood忽略未使用的导入
`-q`告诉sfood安静关于调试信息
  

要从标准库过滤掉模块，可以使用

  sfood -fuq package.py | sfood-filter-stdlib | sfood-target-files 
  

正如你已经注意到的，如果还有其他目录忽略，您也可以使用 sfood -I 标志。

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.

(I'd have thought that getting at least first-level dependencies could be mechanized; even a 98 % solution would be better than avalanching downloads.)

A related question: pip-upgrade-package-without-upgrading-dependencies

解决方案

Snakefood

sfood -fuq package.py | sfood-target-files 

will list the dependencies.

`-f` tells sfood to follow dependencies recursively
`-u` tells sfood to ignore unused imports
`-q` tells sfood to be quiet about debugging information

To filter out modules from the standard library, you could use

sfood -fuq package.py | sfood-filter-stdlib | sfood-target-files 

As you've already noted, if there are other directories you'd like ignored, you can also use the sfood -I flag.
