Wie installiere ich Bibliotheken für Python3 über Cygwin?

1

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

    Note: if you need reliable uninstall behavior, then install
    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)

gcc: command not found - Sie müssen zunächst grundlegende Build-Tools in Cygwin installieren. Haben Sie auch einen "normalen" Windows Python installiert?

@slhck ich glaube schon. Ich finde eine Python3-Installation unter D:\Users\USERNAME\AppData\Local\Programs\Python\Python36-32 Wie kann ich "grundlegende Build-Tools installieren"? Sollten sich Abhängigkeiten nicht selbst installieren?
— Loke Gustafsson
Zusätzlich, C:\Users\USERNAME\AppData\Roaming\Python\Python27\site-packages existiert nicht.

Sie mischen die Cygwin-Python-Installation mit einer Windows-Installation. D:\Users\USERNAME\AppData\Local\Programs\Python\Python36-32 ist nicht cygwin one.
— matzeri
Verwenden Sie entweder Windows Python oder die Cygwin Python. Stelle sicher das python und pip und easy_install usw. Zeigen Sie auf die Cygwin-Version, wenn Sie die letztere bevorzugen. Außerdem müssen Sie (mindestens) installieren gcc und make über das Cygwin-Installationsprogramm.
