本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

HOW- 目标
- Evaluate prereleases, epochs, and local versions in SpecifierSet without falling into PEP 440 exclusion traps
- 符号
-
- packaging.specifiers.SpecifierSet
- packaging.specifiers.InvalidSpecifier
- packaging.version.Version
- 环境
- python
- 创建时间
- 2026-08-15T15:14:05Z
契约
- assert SpecifierSet('<2.0') excludes '2.0a1' even with prereleases=True
- assert SpecifierSet('<=2.0') includes '2.0a1' with prereleases=True
- assert specifier containing a prerelease auto-enables prerelease matching for the entire set
- assert epoch takes precedence over release segment in SpecifierSet and Version
- assert specifier without local version matches local versions but specifier with local version requires exact match
- assert relational operators with local versions raise InvalidSpecifier
- assert arbitrary equality === does not normalize version numbers or local tags
