Ich versuche, eine Umgebung in Windows 10 einzurichten, in der ich in Python 3 programmieren und Bibliotheken und Module nach Belieben verwenden kann. Ich bin anscheinend nicht in der Lage, dies durch Cygwin zu erreichen.
EDIT: Ich habe viel von dieser Frage umgeschrieben, um relevanter zu sein. Ab hier gibt es bessere Details.
Über das Cygwin-Installationsprogramm python3, python3-devel, python3-setuptools, gcc und make wird kommissioniert und montiert.
Ich habe pip / pip3 installiert (und habe sichergestellt, dass es nicht mit Python von Drittanbietern interferiert) und versuche, numpy zu installieren. Das ist der Fehler, den ich beim Laufen bekomme $ pip3 install numpy:
(Beide $ python3 und $ easy_install-3.6 arbeiten und sind von "normalem" Python isoliert, obwohl $ easy_install-3.6 gibt die gleichen Fehler aus wie $ pip3 )
$ pip3 install numpy

with pip instead of using `setup.py install`:
- `pip install .` (from a git repo or downloaded source
release)
- `pip install numpy` (last NumPy release on PyPi)
