当执行

pip install paddlehub

在终端安装执行后出现以下错误内容：

此时登入链接 需要下载相应库的whl：

如果下载tar.gz或者whl仍然出错时（tar.gz仍然报以上错误，whl则出现平台不支持问题）：

需要进入python查询pip所支持的whl（此查询法只适用于pip=20.0.1，若更低版本则需要更换查询方式） ：

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

如果没有支持的，更新pip之后再安装：

pip install --upgrade pip

pip install shellcheck_py-0.7.2.1-py2.py3-none-manylinux1_x86_64.whl 

pip install paddlehub

安装成功：

进入python后可以正常import，即为安装成功：

import paddlehub
