Python将DLL复制到Windows上的站点包

Question

I am writing a python extension module that needs to link with a third-party DLL. How can I copy this DLL to the site-packages directory using distutils (ie in my setup.py file)?

Answer 1

Put your DLL in the package_data argument of your setup() (see the Installing Package Data section of the distutils documentation for details).

If you need to put the DLL outside of the package directory , you can use the data_files option. For example to put it in the site-packages directory:

import distutils.sysconfig

setup(
    # [...]
    data_files = [(distutils.sysconfig.get_python_lib(), ["/path/to/the/DLL"])],
)
