Python无法找到没有安装Anaconda的软件包

我正在尝试使用apt-get为python 3安装kivy：

    sudo apt-get install python3-kivy

并安装在

    /usr/lib/python3/dist-packages

但是，当我尝试在python中加载它时，我收到了ModuleNotFoundError

    Python 3.6.3 |Anaconda custom (64-bit)| (default, Oct 13 2017, 12:02:49) 
    [GCC 7.2.0] on linux
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import kivy
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ModuleNotFoundError: No module named 'kivy'

当我从python检查系统路径时，我仅在Anaconda中获得软件包：

    >>> import sys
    >>> print('\n'.join(sys.path))

    /home/santiago/anaconda3/lib/python36.zip
    /home/santiago/anaconda3/lib/python3.6
    /home/santiago/anaconda3/lib/python3.6/lib-dynload
    /home/santiago/anaconda3/lib/python3.6/site-packages
    /home/santiago/anaconda3/lib/python3.6/site-packages/torchvision-0.2.0-py3.6.egg

有什么方法可以包含Anaconda的“ / usr / lib / python3”路径吗？

谢谢。
