azure-storage Python Modul auf Azure Web App einbinden

Es gibt bei Azure Web Apps zurzeit einen Bug beim Verwenden des azure-storage Moduls mit Python 3.4. Wenn man mit der requirements.txt über Git versucht das Modul azure-storage einzubinden erhält man den Fehler Unable to find vcvarsall.bat.

Fehlerbeschreibung

Azure Web Apps verwendet Python in der Version 3.4 und pip in der Version 1.5.6. In dieser pip Version gibt es den Parameter –find-links nicht, der aber zum installieren verwendet wird.

Workaround

  1. Beim Azure Portal anmelden
  2. Die Web App auswählen
  3. In dem Menü auf der linken Seite auf Advanced Tools klicken
  4. Auf den Link: Go klicken
  5. Oben im Menü auf Tools –> Download deployment script und die Zip Datei deploymentscript.zip herunterladen
  6. Datei entpacken und den Inhalt in euer git repository kopieren.
  7. Die Datei deploy.cmd editieren
  8. Zeile[code]echo Pip install requirements. env\scripts\pip install -r requirements.txt[/code] abändern in:[code]echo Upgrade pip package. env\scripts\python -m pip install pip –upgrade IF !ERRORLEVEL! NEQ 0 goto error echo Pip install requirements. env\scripts\pip install -r requirements.txt[/code]
  9. Die beiden neuen Dateien zu git hinzufügen (git add .), commiten und erneut pushen.
