如何在Python setup.py中递归添加包数据？ [英] How to add package data recursively in Python setup.py?

问题描述

我有一个新的库，其中必须包含许多小数据文件的子文件夹，并且我正在尝试将它们添加为包数据。想象我的图书馆是这样的：

I have a new library that has to include a lot of subfolders of small datafiles, and I'm trying to add them as package data. Imagine I have my library as so:

 library
    - foo.py
    - bar.py
 data
   subfolderA
      subfolderA1
      subfolderA2
   subfolderB
      subfolderB1 
      ...

我想通过setup.py在所有子文件夹中添加所有数据，但是似乎我必须手动进入每个子文件夹（有100个等等），然后添加一个 init .py文件。此外，setup.py会递归找到这些文件，还是我需要在setup.py中手动添加所有这些文件，例如：

I want to add all of the data in all of the subfolders through setup.py, but it seems like I manually have to go into every single subfolder (there are 100 or so) and add an init.py file. Furthermore, will setup.py find these files recursively, or do I need to manually add all of these in setup.py like:

package_data={
  'mypackage.data.folderA': ['*'],
  'mypackage.data.folderA.subfolderA1': ['*'],
  'mypackage.data.folderA.subfolderA2': ['*']
   },

我可以执行此操作与剧本，但似乎超级痛苦。

I can do this with a script, but seems like a super pain. How can I achieve this in setup.py?

PS，这些文件夹的层次结构很重要，因为这是一个包含实质文件的数据库，我们希望文件树成为在将它们通过GUI呈现给用户时保留下来，因此使该文件结构保持完整是我们的优势。

PS, the hierarchy of these folders is important because this is a database of material files and we want the file tree to be preserved when we present them in a GUI to the user, so it would be to our advantage to keep this file structure intact.

推荐答案

1. 使用 Setuptools 代替distutils。


2. 使用数据文件代替打包数据。这些不需要 __ init __。py 。



3. 使用标准Python代码生成文件和目录列表，而无需编写它的字面意思是：

1. Use Setuptools instead of distutils.
2. Use data files instead of package data. These do not require __init__.py.

3. Generate the lists of files and directories using standard Python code, instead of writing it literally:

data_files = []
directories = glob.glob('data/subfolder?/subfolder??/')
for directory in directories:
    files = glob.glob(directory+'*')
    data_files.append((directory, files))
# then pass data_files to setup()
