cpalgotithm安装大坑

安装cpalgotithm时遇到的大坑！
1.直接pip install cpalgorithm不行 加个豆瓣源就好了 使用下面的命令
pip install cpalgorithm -i http://pypi.doubanio.com/simple/ --trusted-host pypi.doubanio.com

2.pip install cpalgorithm -i http://pypi.doubanio.com/simple/ --trusted-host pypi.doubanio.com遇到问题，报 ERROR: Cannot uninstall ‘llvmlite’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.）这个错误，

解决办法：
先输入： pip install --ignore-installed llvmlite

再：pip install cpalgorithm -i http://pypi.doubanio.com/simple/ --trusted-host pypi.doubanio.com
成功！
