backports/lzma/_lzmamodule.c(115) : schwerer Fehler C1083: Include-Datei „lzma.h“ kann nicht geöffnet werden: Keine solche Datei oder kein solches Verzeichnis

Question

Ich habe einen Windows 7-PC mit Visual Studio 2015 Upgrade 3, und ich möchte die Bibliothek backports.lzma für Python mit pip installieren.

Ich habe XZ Utils heruntergeladen und im Ordner „Programme“ entpackt. (XZ Utils ist für die Installation der Backports-Bibliothek erforderlich, wie inPypi-Website)

Dies ist die Pip-Ausgabe:

Unter Program Files\xz\include befindet sich die Datei lzma.h. Wie muss der Header verknüpft werden, damit er erkannt wird?

Answer 1

Laden Sie die entsprechende Wheel-Datei (.whl) herunter vonhttps://www.lfd.uci.edu/~gohlke/pythonlibs/#backports.lzma

Installation auf Python_2.7 Windows_64_Bit, zum Beispiel:

pip2.7 install c:\downloads\backports.lzma‑0.0.12‑cp27‑cp27m‑win_amd64.whl
