Python 语法问题-module ‘pip._internal‘ has no attribute ‘pep425tags‘. 原因及解决办法，32位、64位查看pip支持万能方法
方法一：新方法篇
直接用pip debug --verbose 命令即可看 pip 支持。
注： 感谢 lukea 小伙伴的分享！
详细代码如下：
C:\Users\Administrator>pip debug --verbose

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())
