我没有任何蛋黄，yolk3k或pip install -v的运气，但我最终使用了这个(从eric chiang的答案改编到Python 3):

import json
import requests
from distutils.version import StrictVersion

def versions(package_name):
    url = "https://pypi.python.org/pypi/{}/json".format(package_name)
    data = requests.get(url).json()
    return sorted(list(data["releases"].keys()), key=StrictVersion, reverse=True)

>>> print("\n".join(versions("gunicorn")))
19.1.1
19.1.0
19.0.0
18.0
17.5
0.17.4
0.17.3
...

另一种解决方案是使用仓库api:

https://warehouse.readthedocs.io/api-reference/json/#release

例如，对于Flask:

import requests
r = requests.get("https://pypi.org/pypi/Flask/json")
print(r.json()['releases'].keys())

将打印:

dict_keys(['0.1', '0.10', '0.10.1', '0.11', '0.11.1', '0.12', '0.12.1', '0.12.2', '0.12.3', '0.12.4', '0.2', '0.3', '0.3.1', '0.4', '0.5', '0.5.1', '0.5.2', '0.6', '0.6.1', '0.7', '0.7.1', '0.7.2', '0.8', '0.8.1', '0.9', '1.0', '1.0.1', '1.0.2'])

这是Py3.9+版本的Limmy+EricChiang的解决方案。

import json
import urllib.request
from distutils.version import StrictVersion


# print PyPI versions of package
def versions(package_name):
    url = "https://pypi.org/pypi/%s/json" % (package_name,)
    data = json.load(urllib.request.urlopen(url))
    versions = list(data["releases"])
    sortfunc = lambda x: StrictVersion(x.replace('rc', 'b').translate(str.maketrans('cdefghijklmn', 'bbbbbbbbbbbb')))
    versions.sort(key=sortfunc)
    return versions

以下是我在jq中对列表进行排序的答案(对于那些使用sort -V不可用的系统的人):

$ pythonPackage=certifi
$ curl -Ls https://pypi.org/pypi/$pythonPackage/json | jq -r '.releases | keys_unsorted | sort_by( split(".") | map(tonumber) )'
  ............. 
  "2019.3.9",
  "2019.6.16",
  "2019.9.11",
  "2019.11.28",
  "2020.4.5",
  "2020.4.5.1",
  "2020.4.5.2",
  "2020.6.20",
  "2020.11.8"
]

获取包的最新版本号:

$ curl -Ls https://pypi.org/pypi/$pythonPackage/json | jq -r '.releases | keys_unsorted | sort_by( split(".") | map(tonumber) )[-1]'
2020.11.8

或者更快一点:

$ curl -Ls https://pypi.org/pypi/$pythonPackage/json | jq -r '.releases | keys_unsorted | max_by( split(".") | map(tonumber) )'
2020.11.8

或者更简单一点:):

$ curl -Ls https://pypi.org/pypi/$pythonPackage/json | jq -r .info.version
2020.11.8

pypi版本包出色地完成了以下工作:

$ pip3 install pip-versions

$ pip-versions latest rsyncy
0.0.4

$ pip-versions list rsyncy
0.0.1
0.0.2
0.0.3
0.0.4

这甚至可以在Nexus (sonatype)代理后面工作!
