python - 没有名为 soundfile 的模块

Question

每当我尝试导入 soundfile 时，我都会收到错误

ImportError: No module named soundfile

我安装 pysoundfile 似乎没有问题:

$ sudo pip install pysoundfile
The directory '/Users/theonlygusti/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
