ImportError：无法使用python 2.7.12找到vcvarsall.bat

Question

我是python的新手，我想在Windows 64位上的python 2.7.12中使用模块“ lic_internal”，但出现以下错误：

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

  File "D:\Programme\Python27\lib\site-packages\pyximport\pyximport.py", line 234, in load_module exec("raise exc, None, tb", {'exc': exc, 'tb': tb})

  File "D:\Programme\Python27\lib\site-packages\pyximport\pyxbuild.py", line 102, in pyx_to_dll dist.run_commands()

  File "D:\Programme\Python27\lib\distutils\dist.py", line 972, in run_command cmd_obj.run()
  File "D:\Programme\Python27\lib\site-packages\Cython\Distutils\build_ext.py", line 164, in run _build_ext.build_ext.run(self)
  File "D:\Programme\Python27\lib\distutils\command\build_ext.py", line 339, in run self.build_extensions()
  File "D:\Programme\Python27\lib\site-packages\Cython\Distutils\build_ext.py", line 172, in build_extension self.build_extension(ext)
  File "D:\Programme\Python27\lib\distutils\command\build_ext.py", line 498, in build_extension depends=ext.depends)
  File "D:\Programme\Python27\lib\distutils\msvc9compiler.py", line 474, in compile self.initialize()
  File "D:\Programme\Python27\lib\distutils\msvc9compiler.py", line 384, in initialize vc_env = query_vcvarsall(VERSION, plat_spec)
  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']

我已经安装了“ Visual C ++ for Python 2.7”，并尝试按以下方式更改“ Python27 \\ lib \\ distutils \\ msvc9compiler.py”中的路径：

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"))

这意味着我在“ vcvarsall”中保存了确切的路径。

然后我得到以下错误：

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

File "D:\Programme\Python27\lib\distutils\msvc9compiler.py", line 549, in compile raise CompileError(msg)  

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"]

此外，我在计算机上安装了Visual C ++ 2013，但是当我下载python的C ++编译器软件包时，应该没有必要，对吗？

如果您仍然有问题，可以通过卸载系统中的其他python来解决。 为了确保您需要使用https://stackoverflow.com/a/30272728/7497110定义要使用的python的路径，然后打开msvc9compiler.py并执行此操作https://github.com/cython/ cython / wiki / CythonExtensionsOnWindows 。 然后，您可能会遇到众所周知的头文件问题（即* .h没有此类文件或目录）。 在这种情况下，您可以使用http://www.pythonlibrary.org/notes/open_glcontext_notes.htm中的说明。 请记住要更新python，尤其是distutils和numpy。 请让我知道问题是否解决。
