Python setup.py：data_files无法复制“目录”：不存在或不是常规文件

问题描述

我具有以下python项目结构：

.
├ setup.py
├ doc
|   ├ file.css
|   ├ file.html
|   └ file.js
└ src
    ├ matlabsources
    |             └ <several folders architecture with .m and .slx files>
    └ mypythonpackage
        ├ __init__.py
        └ <several sub packages architecture with python files>

我想将doc文件夹中的所有文件添加到我的whl分发文件中。

setuptools.setup(
    name='myproject',author='me',packages=setuptools.find_packages(where='src',include=['packages*']),package_dir={'': 'src'},data_files ={'documentation': find_data_files('doc'),'matlab': find_data_files('src/matlabsources')},include_package_data=True,install_requires=make_deps(REQS_FILENAME),python_requires='>= 2.7',# Only compatible with Python 2.7.* and 3+
    use_scm_version={'version_scheme': simple_version},# setuptools_scm: the blessed package to manage your versions by scm tags
    setup_requires=make_deps(SETUP_FILENAME),cmdclass=dict(bdist_egg=custom_bdist_egg,build=custom_build,activateIniGeneration=activateIniGeneration)
)


def find_data_files(directory):
    """
    Using glob patterns in ``package_data`` that matches a directory can
    result in setuptools trying to install that directory as a file and
    the installation to fail.

    This function walks over the contents of *directory* and returns a list
    of only filenames found.
    """

    strip = os.path.dirname(os.path.abspath(__file__))

    result = []
    for root,dirs,files in os.walk(directory):
        for filename in files:
          filename = os.path.join(root,filename)
          result.append(os.path.relpath(filename,strip))

    print("\n".join(result))
    return result

我收到以下错误：

error: can't copy 'documentation': doesn't exist or not a regular file

据我所知，“文档”是相对于sys.prefix的目标目录，通常它不存在。

我正在使用以下命令进行构建：

python setup.py bdist_wheel --universal

我也有这个警告

warning: install_data: setup script did not provide a directory for 'documentation' -- installing right in 'build\bdist.win32\wheel\myproject-1.7.z_gfdc81e60.d20201112.data\data'

这让我认为我需要对setup.py进行进一步配置才能使它工作

我在哪里错了？

解决方法

假设项目目录结构为：

<html>
<div id="id" class="class">
  <child>
    Before element is <strong>showing</strong>
  </child>

</div>
<style>
  #id.class>child:before {
    content: 'before'!important;
    border: 1px solid red;
  }
</style>

</html>

使用myproject ├── doc │ ├── alpha │ │ ├── file.css │ │ ├── file.html │ │ └── file.js │ ├── file.css │ ├── file.html │ └── file.js ├── MANIFEST.in ├── setup.cfg ├── setup.py └── src ├── matlabsources │ ├── bravo │ │ ├── file.m │ │ └── file.slx │ ├── file.m │ └── file.slx └── mypythonpackage ├── charlie │ └── __init__.py └── __init__.py，您可以指定要添加到_source发行版（ sdist ）的其他文件。

MANIFEST.in

setuptools 脚本recursive-include doc *.css recursive-include doc *.html recursive-include doc *.js recursive-include src/matlabsources *.m recursive-include src/matlabsources *.slx应该如下所示：

setup.py

这会导致 sdist ：

#!/usr/bin/env python3

import setuptools

def _find_packages():
    packages = setuptools.find_packages(where='src')
    packages.append('mypythonpackage.doc')
    packages.append('matlabsources')
    return packages

def _main():
    setuptools.setup(
        # see 'setup.cfg'
        #
        packages=_find_packages(),include_package_data=True,package_dir={
            'mypythonpackage': 'src/mypythonpackage','mypythonpackage.doc': 'doc','matlabsources': 'src/matlabsources',},)


if __name__ == '__main__':
    _main()

和方向盘：
