无法从github安装python库

Question

My OS is OSX 10.10.5 and I use Anaconda distribution for python. I am trying to install the following library from github: https://github.com/gmum/pykernels

When I try to use pip install:

pip install git+https://github.com/gmum/pykernels.git

I get the following error:

Collecting git+https://github.com/gmum/pykernels.git
  Cloning https://github.com/gmum/pykernels.git to /var/folders/dd/98c207155h57757dtxkyp44r0000gn/T/pip-x7zo1w22-build
    Complete output from command python setup.py egg_info:

Pip install works well for other libraries and my setuptools is also up to date.

Answer 1

The problem is, that library doesn't have a setup.py file. pip executes/follows this file. so that library cannot be installed using pip. You can, however, download and put that library (the pykernels folder inside the repo) in your current folder or add it's path to sys.path like this:

import sys
sys.path.append("Path to pykernels repo") 

Be sure to install their dependencies using pip like this:

pip install numpy scipy scikit-learn

Then you can just use import pykernels in your script.

Edit : setup.py is now integrated to the repository and now you can just use pip :

pip install git+https://github.com/gmum/pykernels.git

Answer 2

Seems that https://github.com/gmum/pykernels.git does not contain valid installable python package. There is no setup.py file in repo root directory but setup.py is required to installation.

Answer 3

The repository is missing a setup.py file. Without this pip does not know how to install the module/package.

It looks like it's just a plain package without any setup scripts. You'll need to clone it and use it by copy/pasting it into your project or write your own setup.py file.

Here's the documentation . It's pretty straight forward.
