Warum schlägt die Installation von Matplotlib für Python v3.4 unter Windows 7 (x64) fehl?

Question

ich heute Nachmittag aufgeregt installiert Python v3.4, wie es jetzt mit PIP kommt darin vorge verpackt aber pip install matplotlib ergab eine eher enttäuschende Antwort eingeben:

C:\Users\jonc>pip install matplotlib

Es in the matplotlib docs einige zu erwähnen ist unter Windows auf die Installation, der angibt, numpy möglicherweise müssen zuerst installiert werden, aber das scheint auch zum scheitern verurteilt:

C:\Users\jonc>pip install numpy

Was fehlt mir hier? Mein Python ist ziemlich eingerostet, aber ich hatte unter dem Eindruck, pip installierte Abhängigkeiten selbst?

Ich hatte gehofft, wir über den Alptraum waren, die verwendet werden, um versuchen, Python unter Windows zu installieren, aber es scheint nicht ...

Answer 1

Sie benötigen einen Arbeits C-Compiler (vorzugsweise gcc) installiert sein, um installiere matplotlib aus Quellen (zB mit pip). Sie scheinen das nicht auf Ihrer Windows-Box zu haben. Es ist wahrscheinlich besser, wenn Sie darauf warten, dass die Windows-Binärdateien von Matplotlib für Python 3.4 freigegeben werden, was Sie verwenden. Oder Sie können auf python 3.3 downgraden und die vorgefertigten Windows-Binärdateien von matplotlib für diese Version von http://matplotlib.org/downloads.html herunterladen.

Ich war in der gleichen Situation nach dem Upgrade auf Python 3.4. Ich habe Visual Studio 2010 installiert, aber Pythons Pip-Build-Prozess zu bekommen, um das richtig zu verwenden, ist ein großer Schmerz in den Arsch. Ich konnte inoffizielle vorkompilierte Binärdateien von numpy und matplotlib für Python 3.4 unter http://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib finden. Diese sind mit Visual Studio erstellt, so dass es möglich ist, es zu schaffen, aber ich habe nicht die Geduld, um die scharfen Details herauszufinden. Übrigens müssen Sie auch python-dateitil, pyparsing und das Modul/library namens six aus dem gleichen Repository installieren, damit einige grundlegende Matplotlib-Beispiele funktionieren. [Hut Tipp an: ImportError: matplotlib requires dateutil]. Sie können dem Verantwortlichen dieser letzten Sammlung von Binärdateien wahrscheinlich eine E-Mail schicken, um Tipps zu erhalten, wie es geht ... und vielleicht lassen Sie uns wissen, worum es geht. (Sie scheinen Visual Studio 2008 installiert zu haben [MSVC 9], oder zumindest Ihre Python 3.4-Installation scheint zu glauben, dass Sie sie haben und versucht, sie zu verwenden.)

Answer 2

Wenn Sie mit Python 3.4 arbeiten, verwenden Sie folgende Versionen von numpy, scipy, etc Beobachter folgende bitte: 1. Verwendung 32-Bit-Version von python 3.4 2. für einzelne Benutzer installieren (für alle Pakete Installation fehl)

numpy: 1.8.2 (i verwendet Windows Installer-Version)
vispy: 0.2.1 (im Grunde herunterladen tar.gz Datei, extrahieren Sie es und führen Sie Python setup.py installieren)
scipy: 0.14.0 (ich Windows-Installer-Version verwendet)
Pandas: 0.14.0 (i verwendet Windows Installer-Version)
openpyxl: 1.8.6 (im Grunde tar.gz-Datei herunterladen, entpacken und ausführen Python setup.py install)

einmal getan Sie überprüfen installierten Pakete von 1. Lauf py von OS-Eingabeaufforderung 2. Verwendung folgenden Befehl von Paket import *

[ersetzen Paket mit Ihrem gewünschten Paket, zB, Numpy] wenn keine Ausgabe angezeigt wird, ist es Ihre Installation bedeuten ist OK

pyparsing installieren pip installieren läuft pyparsing

für matplotlib aktuellen Release Candidate verion (1.4.0rc2) verwenden

http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-1.4.0rc2/

es unterstützt Python 3.4. Aber denken Sie daran, weiterhin nach Updates für Matplotlib für die endgültigen Versionen zu suchen.
