解决办法：修改 Pipfile 文件，将[[source]] 下的 url 改为清华的 pypi 源 https://pypi.tuna.tsinghua.edu.cn/simple
如下：

[[source]]
name = "pypi-tsinghua"
url = "https://pypi.tuna.tsinghua.edu.cn/simple/"
verify_ssl = true

然后再尝试安装，成功！

附：pip安装timeout解决办法：`pip3 install --index-url https://pypi.tuna.tsinghua.edu.cn/simple/ PyQt5`
