python提示“orange3 3.4.1 requires keyrings.alt, which is not installed.”

报错提示“orange3 3.4.1 requires keyrings.alt, which is not installed.”

直接开始搜keyrings.alt，我们发现最顶头的连接PyPI，https://pypi.org/project/keyrings.alt/#files
点击链接，Download files，我下载的是tar.gz的压缩文件，然后解压，cmd命令启动，cd到下载路径，然后python setup.py install。
