pip安装问题汇总

安装gensim

遇到了如下报错

Cannot uninstall 'scipy'. 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.

在stackoverflow查询，得到如下方法解决

You can upgrade  without uninstall the old version

问题原因是我在安装gensim的时候发现我原来已经安装的scipy，所以安装不知道如何选择文件夹。解决方式是要么卸载原来的scipy，要么忽略掉这个安装。我选择忽略：输入如下代码

sudo -H pip install gensim --ignore-installed -U scipy

然后就成功啦
