Librosa是一个用于音频、音乐分析、处理的python工具包，一些常见的时频处理、特征提取、绘制声音图形等功能应有尽有，功能十分强大
anaconda prompt下输入pip install librosa报错。
报错内容：
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.
WARNING: You are using pip version 19.3.1; however, version 20.0.2 is available.
You should consider upgrading via the ‘python -m pip install --upgrade pip’ command.
按照报错内容的提示 输入python -m pip install --upgrade pip，再输入pip install librosa。还是报错
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.
查了一些教程，解决办法：先输入pip install --ignore-installed llvmlite，再输入pip install librosa即可解决。
