"ImportError: No module named scipy" after installing the scipy package
提问by Philip R.
So I recently tried to install scipy on my Raspbian (Debian for Raspberry Pi) operating system using sudo pip install scipy. The command worked without too much trouble, and I can see the file located under pi/build/scipy.
所以我最近尝试在我的 Raspbian（Raspberry Pi 的 Debian）操作系统上使用sudo pip install scipy. 该命令运行起来没有太多麻烦，我可以看到位于pi/build/scipy.
However, when I actually try to import it in a python program, it gives me ImportError: No module named scipyI'm not really sure how to go about pointing the OS in the correct location to import the scipy module.
但是，当我实际尝试在 python 程序中导入它时，它让我ImportError: No module named scipy不确定如何将操作系统指向正确的位置以导入 scipy 模块。

Unless you are inside the pip environment it won't work, at all. I would recommend you to install the python-scipypackage instead, which would assure you that will work:
除非您在 pip 环境中，否则它根本无法工作。我建议您改为安装该python-scipy软件包，这将确保您可以正常工作：

I think you have a problem with the permissions after installing with sudo pip. (
我认为您在使用sudo pip. (
A quick solution to this problem could be to install scipy with
这个问题的一个快速解决方案可能是安装 scipy
sudo -i
pip install scipy
To get the sudo-install working you might need to change your default umask(umask 0022).
要使sudo-install 工作，您可能需要更改默认值umask( umask 0022)。
