module ‘pip‘ has no attribute ‘pep425tags‘的解决方案

问题描述

在查看pip支持的文件名和版本时，常会提示module ‘pip’ has no attribute ‘pep425tags’，这主要是使用的pip版本的问题。

解决方法

win32常用：
import pip;
print(pip.pep425tags.get_supported())

amd64常用：

1. import pip._internal
   print(pip._internal.pep425tags.get_supported())
   或
2. import pip._internal.pep425tags
   或
3. import wheel.pep425tags as w

但是这些在我的电脑上都不管用，有用的命令为在CMD执行：
python -m pip debug --verbose

运行结果

执行：import pip;
print(pip.pep425tags.get_supported())
输出：Traceback (most recent call last):
