python - 使用 setuptools 构建包时如何避免收到无用的警告？

Question

似乎 setuptools 触发了各种警告，这些警告实际上是零值，我想摆脱它们，因为它们正在向持续集成进程发送垃圾信息，使发现真正的警告变得更加困难。

以下是我确实想要摆脱的那些:

python setup.py -q bdist_wheel
warning: no previously-included files matching '__pycache__' found under directory '*'
warning: no previously-included files matching '*.pyc' found under directory '*'
warning: no previously-included files matching '*.pyo' found under directory '*'
warning: no previously-included files matching '*.orig' found under directory '*'
warning: no files found matching '*.md' under directory 'releases'
warning: no files found matching '*.rst' under directory 'releases'
warning: no files found matching '*.json' under directory 'releases'
warning: no previously-included files matching '*' found under directory 'examples/node_modules'
no previously-included directories found matching 'examples/node_modules'
warning: build_py: byte-compiling is disabled, skipping.

warning: install_lib: byte-compiling is disabled, skipping.

看来这一切都是MANIFEST.in引起的文件，但那里的条件确实有存在的理由，而当排除模式确实找不到匹配的文件时，这显然不是生成警告的原因之一？!

目前我只找到一个解决此问题的方法:
导出 PYTHONDONTWRITEBYTECODE=
这将避免在构建过程中收到这些恼人的警告。
