Hi,
I'm trying to create nix-packages from some of my own Python-modules.
So, I followed the Nixpkgs manual, but it did not work as described:
Section 8.10.1.2.1. Python packaging on Nix:
- 1st shell.nix-example: local toolz package [1]
1. variable "licenses" is not found:
user@host:~/tmp/_$ nix-shell
error: undefined variable ‘licenses’ at /home/rk/tmp/_/shell.nix:15:15
(use ‘--show-trace’ to show detailed location information)
2. after removing the license-line, I can start a nix-shell, but the toolz
package is not available:
user@host:~/tmp$ nix-shell
...
[nix-shell:~/tmp]$ which python3.5
/nix/store/c5c9fs9vh12rr0lvbss1a813xwlwv0zh-python3-3.5.2/bin/python3.5
[nix-shell:~/tmp]$ python3.5
Python 3.5.2 (default, Jun 25 2016, 21:38:40)
[GCC 5.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import toolz
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'toolz'
- 2nd shell.nix-examle: local toolz package + numpy [2]
1. variable "licenses" is not found (as above)
2. tests fail:
...

So, how can I develop with local Python packages or package local Python
modules?
Additionally, I've found several broken links:
I found several broken links:
- buildPythonPackage
https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/python-modules/generic/default.nix
- http://pythonhosted.org/setuptools/setuptools.html#development-mode
should probably point to
http://setuptools.readthedocs.io/en/latest/setuptools.html#development-mode
- http://nixos.org/nixpkgs/manual/#ssec-python-development
This anchor des not exist; maybe #development-mode is meant.
- A link-checker (https://validator.w3.org/checklink) reported even more
broken links.
best regards
