Folder for data_files in setup.py build (setuptools)

Question

I am trying to add data_file to setup.py project . I can use file from /tmp/ directory, and cannot use it from current directory of the script:

from setuptools import setup, find_packages
import os

packages = find_packages("src")
foo_path = os.path.dirname(os.path.abspath(__file__)) + '/foo.dat'
print foo_path   # file exists and there full absolute path is printed:
                 # '/home/loom/myapp/foo.dat'

setup(name='myapp',
        version='0.2.0',
        url='http://loom.st',
        author='Loom',
        author_email='[email protected]',
        package_dir={'': 'src'},
        packages=packages,
        py_modules=['my_start'],
# 1.        data_files=[('lib/python', [foo_path])],
# 2.        data_files=[('lib/python', [/tmp/foo.dat])],
        setup_cfg=True,
        )

When the line 1. is uncommented, then python setup.py bdist_rpm failed with message:

running install_data
error: can't copy '/home/loom/myapp/build/bdist.linux-x86_64/rpm/BUILD/myapp-0.2.0/foo.dat': doesn't exist or not a regular file
error: Bad exit status from /var/tmp/rpm-tmp.02mmV8 (%install)

When the line 2. is uncommented, then build is completed ok and includes foo.dat (file /tmp/foo.dat exists)

Why the line 1. induces error and how to avoid it?

Are you working under Windows or *nix? Try to remove the trailing / in /home/loom/myapp/foo.dat/ while in /tmp/foo.dat it seems to be a file and not a dir — linusg

@linusg - I am working on *nix and tmp is in the root directory and file /tmp/foo.dat exists. I'll expand question, thank you — Loom

Maybe defining foo_path as "./foo.dat" if it's in the same directory as the setup file?? — linusg

@linusg - error: can't copy './foo.dat': doesn't exist or not a regular file I started with it. — Loom

The problem here is, that you've given the wrong path to foo.dat, it's given as a directory:

/home/loom/myapp/foo.dat/

Just remove the trailing / at the end, so it's a path to a file:

/home/loom/myapp/foo.dat

If the file really exists, all should be fine now.

Sorry. It was a typo in my question I fixed. Unfortunately the problem with folder still here.
