我想出了一个非常简单的bash脚本。感谢jq的作者。

#!/bin/bash
set -e

PACKAGE_JSON_URL="https://pypi.org/pypi/${1}/json"

curl -L -s "$PACKAGE_JSON_URL" | jq  -r '.releases | keys | .[]' | sort -V

更新: 添加按版本号排序的功能。 添加-L跟随重定向。

您可以尝试安装不存在的软件包版本。然后pip将列出可用的版本

pip install hell==99999
ERROR: Could not find a version that satisfies the requirement hell==99999

你可以用3k的蛋黄来代替蛋黄。Yolk3k是最初的蛋黄的分支，它同时支持python2和3。

https://github.com/myint/yolk

pip install yolk3k

这适用于我在OSX:

pip install docker-compose== 2>&1 \
| grep -oE '(\(.*\))' \
| awk -F:\  '{print$NF}' \
| sed -E 's/( |\))//g' \
| tr ',' '\n'

它每行返回一个列表:

1.1.0rc1
1.1.0rc2
1.1.0
1.2.0rc1
1.2.0rc2
1.2.0rc3
1.2.0rc4
1.2.0
1.3.0rc1
1.3.0rc2
1.3.0rc3
1.3.0

1.3.2
1.3.3
1.4.0rc1
1.4.0rc2

1.4.2
1.5.0rc1
1.5.0rc2
1.5.0rc3
1.5.0
1.5.1
1.5.2
1.6.0rc1
1.6.0
1.6.1

1.8.0rc1
1.8.0rc2
1.8.0
1.8.1
1.9.0rc1
1.9.0rc2
1.9.0rc3
1.9.0rc4
1.9.0
1.10.0rc1
1.10.0rc2
1.10.0

或获取最新版本:

pip install docker-compose== 2>&1 \
| grep -oE '(\(.*\))' \
| awk -F:\  '{print$NF}' \
| sed -E 's/( |\))//g' \
| tr ',' '\n' \
| gsort -r -V \
| head -1

1.10.0rc2

请记住，必须安装gsort(在OSX上)来解析版本。您可以使用brew install coreutils安装它

在看了一段时间pip的代码之后，负责定位包的代码似乎可以在pip.index中的PackageFinder类中找到。它的方法find_requirement查找InstallRequirement的版本，但不幸的是只返回最新的版本。

下面的代码几乎是原始函数的1:1副本，只是第114行中的返回值更改为返回所有版本。

脚本期望一个包名作为第一个也是唯一的参数，并返回所有版本。

我不能保证正确，因为我不熟悉pip的代码。但希望这能帮到你。

(更新:截至2020年3月，许多人报告说，通过pip install yolk3k安装的蛋黄只返回最新版本。克里斯的回答似乎获得了最多的赞，对我来说很有用)

在pastebin中的脚本可以工作。但是，如果您使用多个环境/主机，这就不太方便了，因为每次都必须复制/创建它。

更好的全面解决方案是使用yolk3k，它可以与pip一起安装。例如，查看Django的可用版本:

$ pip install yolk3k
$ yolk -V django
Django 1.3
Django 1.2.5
Django 1.2.4
Django 1.2.3
Django 1.2.2
Django 1.2.1
Django 1.2
Django 1.1.4
Django 1.1.3
Django 1.1.2
Django 1.0.4

Yolk3k是原蛋黄的一个分支，于2012年停止开发。虽然不再维护蛋黄(如下面的评论所示)，但蛋黄3k似乎是并支持Python 3。

注意:我没有参与蛋黄3k的形成。如果有些东西似乎没有像它应该的那样工作，在这里留下评论应该不会有太大的区别。如果可能的话，请使用yolk3k问题跟踪器，并考虑提交修复程序。
