distutils

I have a python module fully implemented in python. (For portability reasons.) The implementation of a small part has been duplicated in a cython module. To improve perfomance where possible. I know how to install the .c modules created by cython with distutils . However if a machine has no compiler installed, I suspect the setup will fail even though the module is still usable in pure python mode. Is there a way to compile the .c module if possible but fail gracefully and install without it if compiling is not possible? I guess you will have to make some modification both in your setup.py and

Situation This is the structure of an example package: $ tree Foo/ Foo/ ├── setup.py └── src ├── bar.py └── __init__.py The package's name shall be foo however the package's source files are placed in the src folder. The files' contents are: setup.py: from setuptools import setup setup( name='foo', version='1', packages=['foo'], package_dir={'foo': 'src'} ) __init__.py: from .bar import bar print(bar) bar.py: bar = 1 Problem When doing pip install Foo everything is fine and I can use the package as I'd expect: >>> import foo 1 However when I install the package in editable mode ( pip install

一、概念介绍 Python is known for it's “batteries included” philosophy and has a rich standard library。However, being a popular language, the number of third party packages is much larger than the number of standard library packages. So it eventually becomes necessary to discover how packages are used, found and created in Python. 目前python提供的包管理工具有多个，其关系如下： 具体可以参见： http://guide.python-distribute.org/introduction.html 可以看出，Distribute代替了Setuptools, 但将来会被distutils2取代，并作为标准库的一部分。 关于packages的管理，则由pip进行 有关packages的发布，查找的网站是： https://pypi.python.org/pypi Distribute是对标准库disutils模块的增强，disutils主要是用来更加容易的打包和分发包

I have a setup.py file that builds an extension. If I change one of the source files, distutils recognizes this and rebuilds the extension, showing all the compile / link commands. However, if the only thing I change is setup.py (I'm fiddling trying to make library dependencies work), then it doesn't seem to rebuild (e.g., none of the compile/link commands show up). I've tested this by removing one of the source files in the line sources = ['foo.c', 'bar.c' ...] and when I pip install -e . or python setup.py install , it still creates a new file for the extension, but it must be a version

I have tried everything given and the tutorials all point in the same direction about using mingw as a compiler in python instead of visual c++. I do have visual c++ and mingw both. Problem started coming when I wanted to install using pip. It always gave Unable to find vcvarsall.bat So as per suggestions I created a file distutils.cfg under the following path c:/python27/Lib/distutils/ and added the following two lines: [build] compiler=mingw32 However, this file has no effect whatsoever. The same error still exists while using pip. I am trying to install numpy by the way currently although
