error in kubernetes setup command: 'install_requires' must be a string or list of strings

[alexxa]

Following installation instructions in Readme:

git clone --recursive https://github.com/kubernetes-client/python.git
cd python
python setup.py install

returns

error in kubernetes setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers

Hi @alexxa, which version of setuptools do you use (easy_install --version) ? I use virtualenv with setuptools 39.2.0 and it works without any problems.

@tomplus Hello Tomasz, right, the error appears on CentOS 7.5 which goes with setuptools 0.9.8. I have installed 39.2.0, and it works fine then. Do you think adding "Requirements" note in Readme will be beneficial?

@alexxa if you still have the issue then simply install it using pip.

sudo pip install kubernetes

[alexxa]

@abushoeb pip installation works fine. The issue is not about that, but installation from the source. And there is no "Requirements" or "Tested on" notes in Readme, and I ask if it can be useful to add it there.

[tomplus]

@alexxa I did more tests and at least setuptools v 8.0 is needed to parse requirements.txt correctly (http://setuptools.readthedocs.io/en/latest/history.html#id378). It's interesting because requirements.txt requires setuptools>=21.0 (https://github.com/kubernetes-client/python/blob/master/requirements.txt#L4), but this file can't be parsed by very old version 🤦‍♂️

IMO it's worth to add a disclaimer about version of setuptools to readme to section about instalation from sources.

pip install setuptools --upgrade can solve this error. It's worth to try

[EKwongChum]

python -m pip install --upgrade pip setuptools wheel

This command works for me!
