我在这里遵循 Substanced 安装说明http://docs.pylonsproject.org/projects/substanced/en/latest/install.html
步骤：3 $ bin/python -c "from substanced.file import magic; assert magic is not None, 'python-magic not installed'"=>python-magic not installed
所以我跑pip install python-magic=>Requirement already satisfied: python-magic in c:\users\edmunds\appdata\local\programs\python\python36-32\lib\site-packages
任何想法为什么我在这里收到混合信息？
