Python: Package目录不存在

Question

I'm trying to install a python package in windows 10 using the following setup.py file.

"""Setup file for uhd module"""

from setuptools import setup

setup(name='uhd',
      version='3.14.0',
      description='Universal Software Radio Peripheral (USRP) Hardware Driver Python API',
      classifiers=[
          'Development Status :: 4 - Beta',
          'License :: OSI Approved :: GNU General Public License v3 (GPLv3)',
          'Programming Language :: C++',
          'Programming Language :: Python',
          'Topic :: System :: Hardware :: Hardware Drivers',
      ],
      keywords='SDR UHD USRP',
      author='Ettus Research',
      author_email='packages@ettus.com',
      url='https://www.ettus.com/',
      license='GPLv3',
      package_dir={'': 'C:/Users/bcollins/UHD_PY/uhd/host/build/python'}, 
      package_data={'uhd': ['*.so']},
      zip_safe=False,
      packages=['uhd'],
      install_requires=['numpy'])

I execute the script using the command

python setup.py install

I do this from the directory that contains the setup.py file.

This returns the following error

error: package directory 'C:Users\bcollins\UHD_PY\uhd\host\build\python\uhd' does not exist

There is a folder called "uhd" at that location though. The folder contains the __init__.py file

If the script isn't looking for this folder, what is it looking for?

I'm not exactly experienced in this area but my best guess is that its looking for a.so file within the "uhd" folder at that location, but I'm not sure.

I am using python 2.7.

Answer 1

package_dir has to be a relative path, not an absolute path. The distutils layer under setuptools tries to reject absolute paths, but the C: confuses it. It ends up converting your path to

C:Users\bcollins\UHD_PY\uhd\host\build\python\uhd

Note the missing backslash between C: and Users . This path is relative to your current working directory on the C drive ( windows drive handling is weird ), and relative to your working directory, this path is invalid.

Answer 2

This doesn't answer the original question, but it's how I fixed the same error.

I had:

from setuptools import setup, find_packages

setup(
    ...
    packages=find_packages('src', exclude=['test']),
    ...
)

I had added the src argument because my packages are located in src , but it turns out find_packages is smart enough on it's own.

Remove the first argument:

from setuptools import setup, find_packages

setup(
    ...
    packages=find_packages(exclude=['test']),
    ...
)

This was on Python 3.5, but I imagine it applies to most other versions.

Answer 3

我发现当 python 脚本文件夹 (%python_root%\\scripts) 不在环境 PATH 中时，可能会发生此错误。

Answer 4

I had this problem, it turned out that you just need to add a slash after your package directory: packages=['uhd'] should be packages=['uhd/'] .
