从svg转换为pdf

Question

我正在尝试使用以下代码将svg文件转换为pdf,但出现错误

SRC:

from svglib.svglib import svg2rlg
from reportlab.graphics import renderPDF
drawing = svg2rlg("test.svg")
renderPDF.drawToFile(drawing, "test.pdf")

错误:

pydev debugger: starting

    normPath = normaliseSvgPath(d)
  File "C:\Python27\lib\site-packages\svglib\svglib.py", line 146, in normaliseSvgPath
    a = string.replace(a, 'e-', 'ee')
NameError: global name 'string' is not defined

此外,我想避免使用硬文件并使用StringIO来创建临时的svg/pdf文件,但我想svg2rlg只接受一个路径作为输入.

让我工作的是手工编辑:

/Users/<MY_USER>/.virtualenvs/<MY_VENV>/lib/python2.7/site-packages/svglib/svglib.py

并添加此缺失

import string
