具有以下代码设置,以在 Python 中使用 Reportlab 和 Pisa 生成 PDF 文档。
import cStringIO
import ho.pisa as pisa
def html_to_pdf(data, filename, open=False):
pdf = pisa.CreatePDF(
cStringIO.StringIO(data),
file(filename, "wb"))
我的 HTML 文件包含标准的 HTML 内容。
它的完全限定路径以及 .html 扩展名被分配给 output_file 变量。
像这样称呼它:
with open(output_file, "r") as my_file:
contents = my_file.read()
html_to_pdf(contents, dest_pdf_file, open=True)
得到这个错误:
No handlers could be found for logger "sx.pisa3"

这是 pip freeze 产生的“部分列表”。
Pillow==2.3.0
PyPDF2==1.25.1
html5lib==0.999
oneconf==0.3.7.14.04.1
pdfkit==0.5.0
pisa==3.0.33
reportlab==3.0
似乎是一个损坏的安装问题...
有谁知道如何修复这个或任何用于将 HTML 文件生成为 PDF 的替代方法(方法和/或不同的库)?
