python - 使用 py2exe 捆绑时导入错误

Question

我使用 py2exe 捆绑了一个用 python 编写的小脚本。该脚本使用了许多包，其中之一是 reportlab。使用 py2exe 捆绑后，我尝试运行可执行文件，但它返回以下错误:

C:\Python26\dist>DELchek.exe
Traceback (most recent call last):
File "DELchek.py", line 12, in <module>
File "reportlab\pdfgen\canvas.pyc", line 25, in <
File "reportlab\pdfbase\pdfdoc.pyc", line 22, in
File "reportlab\pdfbase\pdfmetrics.pyc", line 23,
File "reportlab\pdfbase\_fontdata.pyc", line 158,
ImportError: No module named _fontdata_enc_winansi

但我可以在 reportlab 文件夹中看到“_fontdata_enc_winansi”模块。谁能帮我解决这个问题。

我在过去将 reportlab 与 py2exe 捆绑在一起时遇到了同样的问题。它动态导入了一堆模块，py2exe 在组装依赖项时无法识别这些模块。暴力修复是直接在您的代码中导入所需的模块:

from reportlab.pdfbase import _fontdata_enc_winansi
from reportlab.pdfbase import _fontdata_enc_macroman
from reportlab.pdfbase import _fontdata_enc_standard
from reportlab.pdfbase import _fontdata_enc_symbol
from reportlab.pdfbase import _fontdata_enc_zapfdingbats
from reportlab.pdfbase import _fontdata_enc_pdfdoc
from reportlab.pdfbase import _fontdata_enc_macexpert
from reportlab.pdfbase import _fontdata_widths_courier
from reportlab.pdfbase import _fontdata_widths_courierbold
from reportlab.pdfbase import _fontdata_widths_courieroblique
from reportlab.pdfbase import _fontdata_widths_courierboldoblique
from reportlab.pdfbase import _fontdata_widths_helvetica
from reportlab.pdfbase import _fontdata_widths_helveticabold
from reportlab.pdfbase import _fontdata_widths_helveticaoblique
from reportlab.pdfbase import _fontdata_widths_helveticaboldoblique
from reportlab.pdfbase import _fontdata_widths_timesroman
from reportlab.pdfbase import _fontdata_widths_timesbold
from reportlab.pdfbase import _fontdata_widths_timesitalic
from reportlab.pdfbase import _fontdata_widths_timesbolditalic
from reportlab.pdfbase import _fontdata_widths_symbol
from reportlab.pdfbase import _fontdata_widths_zapfdingbats

搜索还显示 Sankar 找到了 another solution ，它在安装脚本中包含以下包:

packages=[
    'reportlab',
    'reportlab.graphics.charts',
    'reportlab.graphics.samples',
    'reportlab.graphics.widgets',
    'reportlab.graphics.barcode',
    'reportlab.graphics',
    'reportlab.lib',
    'reportlab.pdfbase',
    'reportlab.pdfgen',
    'reportlab.platypus',
],
