Installation Mayavi: UnicodeEncodeError: 'Charmap' Codec kann nicht codieren Zeichen

Question

Ich versuche, Mayavi auf einem Windows-Computer mit Anaconda 3.6 zu installieren.

Leider bekomme ich einen Fehler, den ich nicht verstehe. Ich entdecke immer noch Python.

Ich habe schon andere ähnliche Probleme im Internet angeschaut, kann aber nichts funktionierendes finden.

Könnten Sie mir bitte helfen?

Answer 1

Schließlich gelang es mir, die Installation von MayaVi, aber ich habe das Problem nicht lösen: Ich habe deinstallierte Anaconda 3.6 und installierte stattdessen Anaconda 2.7. Dann konnte ich alles installieren, was ich brauchte.

Answer 2

hatte ich das gleiche Problem und schaffte es außer Kraft zu setzen, indem die mayavi-4.5.0.zip Datei auf https://pypi.python.org/pypi/mayavi Herunterladen und Kopie einfügen „MayaVi“ Ordner direkt zu Anaconda3 \ Lib

Answer 3

ich das gleiche Problem begegnet. Meine Lösung ist der Download 'mayavi-4.5.0 + vtk81-cp36-cp36m-win_amd64.whl' von https://www.lfd.uci.edu/~gohlke/pythonlibs/ und pip install mayavi-4.5.0 + vtk81-cp36-cp36m-win_amd64.whl direkt.
