ImportError: Nicht finden vcvarsall.bat mit Python 2.7.12

Question

Ich bin ziemlich neu zu Python und ich möchte das Modul "Lic_internal" mit Python 2.7.12 unter Windows 64bit verwenden, aber ich bekomme den folgenden Fehler:

Traceback (most recent call last): 
    File "04_report.py", line 32, in <module> 
import utils_show as ushow 
    File "./libs\utils_show.py", line 45, in <module>

    File "D:\Programme\Python27\lib\distutils\msvc9compiler.py", line 272, in query_vcvarsall raise DistutilsPlatformError("Unable to find vcvarsall.bat") 

ImportError: Building module lic_internal failed: ['DistutilsPlatformError: Unable to find vcvarsall.bat\n'] 

ich habe "Visual C++ für Python 2.7" installiert und versucht, den Weg in ändern "Python27 \ lib \ distutils \ msvc9compiler.py" wie folgt:

def query_vcvarsall(version, arch="x86"): 
"""Launch vcvarsall.bat and read the settings from its environment 
""" 
vcvarsall = find_vcvarsall(version) 
vcvarsall = "C:/Users/Christian/AppData/Local/Programs/Common/Microsoft/Visual C++ for Python/9.0" + "/vcvarsall.bat" 
interesting = set(("include", "lib", "libpath", "path")) 

Was bedeutet, dass ich in „vcvarsall gespeichert "Der genaue Weg.

Dann bekomme ich folgende Fehlermeldung:

Traceback (most recent call last): 
File "04_report.py", line 32, in <module> import utils_show as ushow 
File "./libs\utils_show.py", line 45, in <module> import lic_internal

ImportError: Building module lic_internal failed: ["CompileError: command 'C:\\\\Users\\\\Christian\\\\AppData\\\\Local\\Programs\\\\Common\\\\Microsoft\\\\Visual C++ for Python\\\\9.0\\\\VC\\\\Bin\\\\cl.exe' failed with exit status 2\n"] 

Außerdem habe ich Visual C++ 2013 auf meinem Computer installiert, aber als ich das C++ Compiler-Paket für Python heruntergeladen sollte es nicht notwendig sein, nicht wahr?

Wenn Sie immer noch das Problem haben, löste ich es durch die Deinstallation anderer Pythons im System. Zur Sicherheit müssen Sie den Pfad des Pythons definieren, mit dem Sie arbeiten möchten, indem Sie https://stackoverflow.com/a/30272728/7497110 verwenden, dann öffnen Sie die msvc9compiler.py und tun dies https://github.com/cython/cython/wiki/CythonExtensionsOnWindows. Dann könnten Sie das bekannte Header-Problem (d. H. * .h Keine solche Datei oder Verzeichnis) bekommen. In diesem Fall können Sie die Anweisungen in http://www.pythonlibrary.org/notes/open_glcontext_notes.htm verwenden. Denken Sie daran, die Python insbesondere die Distutils und numpy zu aktualisieren. Bitte lassen Sie mich wissen, wenn das Problem gelöst ist.
