PyPI 是否区分大小写? [英] Is PyPI case sensitive?

问题描述

PyPI 如何处理区分大小写?

How does PyPI handle case sensitivity?

例如，this SO question 记录了 PyPI 拒绝新的如果 FooBar 已经存在，则打包 foobar.

For example, this SO question documents PyPI refusing a new package foobar if FooBar already exists.

针对 pypi.python.org 运行 pip 似乎转换为包的规范案例:

Running pip against pypi.python.org seems to convert to the canonical case for a package:

$ pip install django
Downloading/unpacking django
  Downloading Django-1.7.tar.gz (7.5MB): 7.5MB downloaded

或者:

$ pip install Django
Downloading/unpacking Django
  Downloading Django-1.7.tar.gz (7.5MB): 7.5MB downloaded

但是，在我的 virtualenv 中，似乎只有一些文件属于规范案例:

However, only some files seem to be in the canonical case in my virtualenv:

$ ls ~/pyenvs/test_venv/lib/python2.7/site-packages/ | grep -i django
django/
Django-1.7-py2.7.egg-info/

XML-RPC API 期望什么?我可以总是假设 http://pypi.python.org/simple/foo 和 http://pypi.python.org/simple/FoO 都会返回 HTTP 200?

What does the XML-RPC API expect? Can I always assume that http://pypi.python.org/simple/foo and http://pypi.python.org/simple/FoO will both return HTTP 200?

PyPI 在区分大小写方面的立场是否记录在任何地方?

Is PyPI's position on case-sensitivity documented anywhere?

推荐答案

不，pip 不区分大小写.

No, pip is case insensitive.

分发名称的所有比较必须不区分大小写，并且必须将连字符和下划线视为等效.

All comparisons of distribution names MUST be case insensitive, and MUST consider hyphens and underscores to be equivalent.
