[SOLVED] How to Install Things

chris_crunch · 02-04-2016, 02:21 AM

This might seem like a really dumb question, but for example, I want to use the .np extension in python, which is apparently part of python numpy? So I type...

chris@chris-crunch:~$ wget https://github.com/numpy/numpy.git
--2016-02-04 08:17:42-- https://github.com/numpy/numpy.git

Saving to: ‘numpy.git’

Now what?

Hi...

It's not a dumb question at all. It appears that, from what you posted, the file is not getting downloaded. I ran the same command and saw this...

Code:

aaron@aaron:~$ wget https://github.com/numpy/numpy.git

As to where "numpy.git" is actually located, I will have to search for it and report back. Try it again and see what happens. If nothing else you can always download one of the tarballs here.

Regards...

Hi Chris...

I found it, it was placed in my home folder, in my case: "/home/aaron."

Regards...

Thanks for the advice. To install programs in general, in linux...

What's the general procedure? I'm using wget <copied link from url>

but are there better ways?

ardvark71 · 02-04-2016, 04:17 AM

What distribution and version of Linux are you using?

Regards...

chris_crunch · 02-04-2016, 04:23 AM

Xubuntu 14.04, I think.

I just added it to my sig, because I can tell I'll be around these forums a lot haha

Install stuff from your distro's repositories using the package manager.

Xubuntu may use the Software Center (which I hate) but you can install Synaptic or use apt-get from the command line. I guarantee that python-numpy is in the repos...

amilo · 02-04-2016, 04:51 AM

google for xubuntu.org and GNU/linux

chris_crunch · 02-04-2016, 05:05 AM

What I tried:

chris@chris-crunch:~$ apt-get numpy
E: Invalid operation numpy
chris@chris-crunch:~$ sudo apt-get install numpy
[sudo] password for chris:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package numpy
chris@chris-crunch:~$

numpy.git is a directory, not a file to download. use git clone to clone a git repo.
use apt-get install python-numpy to install it

How did you know to install NumPy, it was the code 'python-numpy' ?

pan64 · 02-04-2016, 05:19 AM

usually the python modules have the name: python-<module>.
If you think your problem is solved please mark the thread solved.

Install Synaptic. When you think you want something, fire up Synaptic and type in the search box. If you typed in "numpy" it will show all packages with "numpy" in the name - then you can highlight each one and read the descriptions.

You need to take some time and read up on Linux in general and package management.

Installing stuff from outside the repos, especially for a newbie, is a great way to break your system quickly...
