Python, Fehler bei der Installation von matplotlib

Question

Betriebssystem: Windows 10

Python Version: 3.9.0

Fehlercode:

ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output. 

Ich habe es versucht:

python -m pip install -U pip
python -m pip install -U matplotlib

hat nicht funktioniert.

und dann habe ich versucht:

pip install --upgrade setuptools

hat das Problem nicht gelöst.

Ich habe weiter gelesen, dass wenn ich die Shell im Administratormodus öffne, das Problem möglicherweise gelöst werden könnte, aber es auch nicht funktioniert hat.

Ich habe jemanden gesehen, der ez-setup für diesen Fehlercode erwähnt hat. Ich habe es installiert, aber das hat auch nicht funktioniert.

Ich weiß nicht, ob es etwas zu tun hat, aber mein C-Verzeichnis sieht folgendermaßen aus:

C:\Users\METİNUSTA

Es hat einen i-Großbuchstaben, der manchmal Probleme mit Anwendungen verursachen kann. Ich kann es nicht ändern, da ich den Windows-Schlüssel meiner Schule verwende und keine Änderungen vornehmen kann. Aus diesem Grund habe ich Python auf D: installiert.

Auch hier meine Pip-Liste für zusätzliche Informationen:

ez-setup    0.9
flake8      3.8.4
mccabe      0.6.1
pip         20.2.4
pycodestyle 2.6.0
pyflakes    2.2.0
setuptools  50.3.2
wheel       0.35.1

und schließlich das ganze Fehlerprotokoll, das ich auf Windows Powershell bekomme:

    Edit setup.cfg to change the build options; suppress output with --quiet.

Answer 1

matplotlib hat noch kein Rad für Version 3.9 erstellt, daher hat Ihr Python versucht, es aus dem Quellcode zu erstellen. Sie sollten ein Downgrade auf Python 3.8 durchführen und dann sollte alles funktionieren

Answer 2

1. "python -m pip install --upgrade pip"

2. "pip install matplotlib == 3.3.1"

Hat für mich gearbeitet.

Answer 3

Dies liegt daran, dass matplotlib keine 3,9 Räder hat.

Zur Vereinfachung der Verwendung von matplotlib können Sie anaconda installieren. In einer Anaconda-Umgebung sind matplotlib, numpy und pandas standardmäßig für in Anaconda installiertes Python verfügbar. Oder Sie können niedrigere Versionen von Python verwenden.
