我在Windows 7平台上运行python脚本时遇到了一些麻烦.我已经安装了Python和cairo,最后一个使用"pip".我正在使用此命令运行脚本:

C:\Python34>python.exe label/make_label.py

我收到以下错误消息:

Traceback (most recent call last):
  File "label/make_label.py", line 6, in <module>
    import cairocffi as cairo
  File "C:\Python34\lib\site-packages\cairocffi\__init__.py", line 41, in <modul
e>
    cairo = dlopen(ffi, *CAIRO_NAMES)
  File "C:\Python34\lib\site-packages\cairocffi\__init__.py", line 34, in dlopen

    return ffi.dlopen(names[0])  # pragma: no cover
  File "C:\Python34\lib\site-packages\cffi\api.py", line 118, in dlopen
    lib, function_cache = _make_ffi_library(self, name, flags)
  File "C:\Python34\lib\site-packages\cffi\api.py", line 411, in _make_ffi_libra
ry
    backendlib = _load_backend_lib(backend, libname, flags)
  File "C:\Python34\lib\site-packages\cffi\api.py", line 400, in _load_backend_l
ib
    return backend.load_library(name, flags)
OSError: cannot load …

试图让这段代码工作：

import cairosvg
import os

path = "D:/PyProjects/Bla/Temp"
os.chdir(path)

cairosvg.svg2pdf(url='Pic.svg', write_to='image.pdf')

但是遇到类似于这篇文章的错误：
