PyInstaller生成的exe不工作，项目使用ReportLab

Question

我正在为我的项目生成一个exe。大约一个月前我的项目没有使用ReportLab时，它没有问题，但是现在，没有那么多了。在

在搜索之后，我发现问题出在一个pyinstaller文件中a missing import。 问题解决了对吗？不完全是。在

现在我得到这个错误。。。在

在四处搜索时，我发现this只导致了一个建议的解决方案，即强制在我的代码文件中导入所有内容。我有太多的报告文件，这让我很难去想。在

我读到一些关于隐藏进口的东西。也许这对我有帮助，但我不知道。任何帮助都将不胜感激。谢谢您。在

编辑：py2exe的similar问题和解决方案。。。。在

Answer 1

将名为hook-reportlab.pdfbase._fontdata.py的文件添加到pyinstaller的hooks子目录中。内容应该是这样的：

hiddenimports = [
    '_fontdata_enc_macexpert',
    '_fontdata_enc_macroman',
    '_fontdata_enc_pdfdoc',
    '_fontdata_enc_standard',
    '_fontdata_enc_symbol',
    '_fontdata_enc_winansi',
    '_fontdata_enc_zapfdingbats',
    '_fontdata_widths_courier',
    '_fontdata_widths_courierbold',
    '_fontdata_widths_courierboldoblique',
    '_fontdata_widths_courieroblique',
    '_fontdata_widths_helvetica',
    '_fontdata_widths_helveticabold',
    '_fontdata_widths_helveticaboldoblique',
    '_fontdata_widths_helveticaoblique',
    '_fontdata_widths_symbol',
    '_fontdata_widths_timesbold',
    '_fontdata_widths_timesbolditalic',
    '_fontdata_widths_timesitalic',
    '_fontdata_widths_timesroman',
    '_fontdata_widths_zapfdingbats']

这对我在pyinstaller2.1中起到了作用。顺便说一句，我从pyinstaller 1.5.1中借用了这个文件，在那里默认安装了它。在

Answer 2

我不知道我这样做是否正确。。。但我开始拔头发了。在

在四处阅读并浪费大量时间之后。。。在

我发现了一篇帖子，建议将整个丢失的库文件夹复制到包含exe的文件夹中。瓦拉！成功了。在

如果有更好/合适的方法来做这件事，请给我指点。在
