方法一：新方法篇
直接用pip debug --verbose 命令即可看 pip 支持。

详细代码如下：

方法二：常规方法篇
64 位 pip 老的查看方法前段时间更新后就不能用了。
之前导入pip._internal就好了。
现在需要导入 pip._internal.pep425tags 才可以。
>>> import pip._internal.pep425tags >>> print(pip._internal.pep425tags.get_supported()) [('cp36', 'cp36m', 'win32'), ('cp36', 'none', 'win32'), ('py3', 'none', 'win32') , ('cp36', 'none', 'any'), ('cp3', 'none', 'any'), ('py36', 'none', 'any'), ('py 3', 'none', 'any'), ('py35', 'none', 'any'), ('py34', 'none', 'any'), ('py33', ' none', 'any'), ('py32', 'none', 'any'), ('py31', 'none', 'any'), ('py30', 'none' , 'any')] >>>
方法三：万能方法
我们直接在 pip 里搜 pep425tags.py 这个文件就行，找到它的位置。
一般导入报错就说明位置不对，每个版本都可能有一些差异，位置可能有变化。
我下载了个 32 位的，查找发现了它的位置，然后直接导入它就行了。
>>> import pip._internal.pep425tags as e >>> print(e.get_supported()) [<cp36-cp36m-win32 @ 36751360>, <cp36-abi3-win32 @ 36751040>, <cp36-none-win32 @ 36751080>, <cp35-abi3-win32 @ 36752000>, <cp34-abi3-win32 @ 36752200>, <cp33-ab i3-win32 @ 40114816>, <cp32-abi3-win32 @ 40114856>, <py36-none-win32 @ 40114936> , <py3-none-win32 @ 40114976>, <py35-none-win32 @ 40115016>, <py34-none-win32 @ 40115056>, <py33-none-win32 @ 40115096>, <py32-none-win32 @ 40115136>, <py31-non e-win32 @ 40115176>, <py30-none-win32 @ 40115216>, <cp36-none-any @ 40115256>, < py36-none-any @ 40115296>, <py3-none-any @ 40115336>, <py35-none-any @ 40115376> , <py34-none-any @ 40115416>, <py33-none-any @ 40115456>, <py32-none-any @ 40115 536>, <py31-none-any @ 40115576>, <py30-none-any @ 40115616>]
