Python setup.py：数据文件无法复制目录：不存在或不是常规文件
问题描述
我有以下的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>
我要将文档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("
".join(result))
return result
我收到以下错误：
error: can't copy 'documentation': doesn't exist or not a regular file
在我的理解中，‘Documentation’是目标目录，相对于sys.prefix，它不存在是正常的。
我正在使用以下命令构建：
python setup.py bdist_wheel --universal
我也有此警告
warning: install_data: setup script did not provide a directory for 'documentation' -- installing right in 'builddist.win32wheelmyproject-1.7.z_gfdc81e60.d20201112.datadata'
这使我认为我的setup.py需要进一步配置才能正常工作
我哪里错了？
解决方案
假定项目目录结构如下：
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
使用MANIFEST.in可以指定要添加到_source分发中的其他文件(sdist)。
recursive-include doc *.css
recursive-include doc *.html
recursive-include doc *.js
recursive-include src/matlabsources *.m
recursive-include src/matlabsources *.slx
setuptools脚本setup.py应如下所示：
#!/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()
这将导致sdist：
$ python3 -m tarfile -l dist/myproject-0.0.0.dev0.tar.gz

myproject-0.0.0.dev0/MANIFEST.in
