解决pip安装报错：is not a supported wheel on this platform

原因1

你下载安装的包不是当前平台所支持的

原因2

你下载的包，不符合你所在的平台的安装whl的名称规范，所以出错。
比如当前我要安装的包是：PyMuPDF-1.16.16-cp36-cp36m-manylinux2010_x86_64.whl

但是在我的系统中使用如下命令安装：

pip3 install PyMuPDF-1.16.11-cp36-cp36m-manylinux2010_x86_64.whl 

但是出现了下面的错误提示：

PyMuPDF-1.16.11-cp36-cp36m-manylinux2010_x86_64.whl is not a supported wheel on this platform.

解决办法1

在shell中运行python,然后输入如下的命令：

>>import pip;print(pip.pep425tags.get_supported())

输出结果如下:

[('cp36', 'cp36m', 'manylinux1_x86_64'), ('cp36', 'cp36m', 'linux_x86_64'), ('cp36', 'abi3', 'manylinux1_x86_64'), ('cp36', 'abi3', 'linux_x86_64'), ('cp36', 'none', 'manylinux1_x86_64'), ('cp36', 'none', 'linux_x86_64'), ('cp35', 'abi3', 'manylinux1_x86_64'), ('cp35', 'abi3', 'linux_x86_64'), ('cp34', 'abi3', 'manylinux1_x86_64'), ('cp34', 'abi3', 'linux_x86_64'), ('cp33', 'abi3', 'manylinux1_x86_64'), ('cp33', 'abi3', 'linux_x86_64'), ('cp32', 'abi3', 'manylinux1_x86_64'), ('cp32', 'abi3', 'linux_x86_64'), ('py3', 'none', 'manylinux1_x86_64'), ('py3', 'none', 'linux_x86_64'), ('cp36', 'none', 'any'), ('cp3', 'none', 'any'), ('py36', 'none', 'any'), ('py3', 'none', 'any'), ('py35', 'none', 'any'), ('py34', 'none', 'any'), ('py33', 'none', 'any'), ('py32', 'none', 'any'), ('py31', 'none', 'any'), ('py30', 'none', 'any')]

其中有一个('cp36', 'cp36m', 'manylinux1_x86_64')意味着如果我要安装python3.6版本的whl，那么我的whl文件中应该是manylinux1_x86_64而不是manylinux2010_x86_64,所以我将文件名改成PyMuPDF-1.16.11-cp36-cp36m-manylinux1_x86_64.whl,然后再进行安装，结果安装成功。

解决方法2

在方法1中，我们通过import pip;print(pip.pep425tags.get_supported())得到文件支持的格式，但是这个命令应该只适用于低版本的pip，比如pip 9.0.1.如果我们的系统是高版本的系统，可以使用下面的命令:

>>> import pip._internal.pep425tags;print(pip._internal.pep425tags.get_supported())

比如如果pip版本是pip 20.0.2，那么得到的结果是:

可以看见支持安装的版本一下子多了起来，所以第二种解决办法就是升级pip，可以通过如下命令升级pip:

python -m pip install --upgrade pip

通常情况下，你的电脑里如果安装了python2.x也同时安装了python3.x，那么应该就会有两个pip。一个是pip2，另一个是pip3。那么可以采用：

pip3 install --upgrade pip
