apt-get install python文件还是只是pip install？

Question

I noticed that i was reading a book mentioning to install numpy and opencv by way of apt-get

apt-get install python-numpy python-opencv

but i can find these in pip by:

pip search numpy

so this begs me to ask the question:

How do these package managers work? If i run pip install numpy will it install to the same directory as apt-get install python-numpy ?

I was curious as to what the best way to do it would be if they are installed into different paths.

I want to say "just do it in pip" but its hard to justify since I dont know how each of the different package managers install things. Are they installed into different directories, but both are on the path to accessible python modules?

Answer 1

pip will work on a larger variety of stock systems/OS's, as opposed to apt-get which typically applies to Linux flavors. For example, apt-get is not available on OS X. You can use Homebrew to get it, but pip was the easiest way for me to install OpenCV. Check https://pypi.python.org/pypi/opencv-python/3.2.0.7 out. Anything in PyPI should be easier to install.

对我来说，最好的位置可以在https://notes.pault.ag/debian-python/找到：如果系统需要一些东西，请使用apt-get（dpkg），如果某些东西不适用于系统（可能是开发） ，使用pip（并且永远不要使用sudo以避免冒险破坏系统）。
