distutils build_py命令很重要，因为它（间接地）被所有创建命令重用分布。如果您重写byte_compile（files）方法，则类似以下内容：

The distutils "build_py" command is the one that matters, as it's (indirectly) reused by all the commands that create distributions. If you override the byte_compile(files) method, something like:

try:
    from setuptools.command.build_py import build_py
except ImportError:
    from distutils.command.build_py import build_py

class build_py(build_py)
   def byte_compile(self, files):
       super(build_py, self).byte_compile(files)
       for file in files:
           if file.endswith('.py'):
               os.unlink(file)

setup(
    ...
    cmdclass = dict(build_py=build_py),
    ...
)

您应该能够做到这一点，以便在将源文件复制到安装目录（这是一个临时目录）之前，将其从构建树中删除。

You should be able to make it so that the source files are deleted from the build tree before they're copied to the "install" directory (which is a temporary directory when bdist commands invoke them).

注意：我尚未测试此代码； YMMV。
