运行fpdf2 Unicode示例代码遇AttributeError：'table__n_a_m_e'无getBestFullName属性

问题描述 #

运行fpdf2官方文档中的Unicode示例代码时，触发以下错误：

Traceback (most recent call last):
File "fpdf2.py", line 12, in
pdf.add_font('DejaVu', fname='DejaVuSansCondensed.ttf')
File "C:\Program Files\Python36\lib\site-packages\fpdf\fpdf.py", line 1916, in add_font
"name": re.sub("[ ()]", "", font["name"].getBestFullName()),
AttributeError: 'table__n_a_m_e' object has no attribute 'getBestFullName'

已在系统中安装DejaVuSansCondensed字体，使用的完整代码如下：

from fpdf import FPDF

pdf = FPDF()
pdf.add_page()

pdf.add_font('DejaVu', fname='DejaVuSansCondensed.ttf')
pdf.set_font('DejaVu', size=14)

text = u"""

pdf.add_font('gargi', fname='gargi.ttf')
pdf.set_font('gargi', size=14)

# Add a AR PL New Sung Unicode font (uses UTF-8)

解决方法 #

1. 切换到正确的fpdf2库 #

错误路径显示调用的是旧版fpdf库的代码，而非目标库fpdf2，执行以下命令修复：

• 卸载旧版fpdf：

  pip uninstall -y fpdf
  

• 安装最新版fpdf2：

  pip install --upgrade fpdf2
  

2. 修改代码导入语句 #

将代码开头的导入行改为：

from fpdf2 import FPDF

3. 确保字体路径正确 #

如果字体文件不在脚本的当前工作目录，需提供完整绝对路径，例如：

pdf.add_font('DejaVu', fname='C:/Windows/Fonts/DejaVuSansCondensed.ttf')

也可直接将字体文件复制到脚本所在文件夹。
