Question

我正在尝试为我的项目生成一个exe。当我的项目没有使用ReportLab时，它在一个月前没有问题，但现在，并没有那么多。

在搜索之后，我发现其中一个pyinstaller文件中的问题是a missing import。问题解决了吗？不完全是。

现在我收到了这个错误......

搜索周围，我发现this只导致一个建议的解决方案，即强制我的代码文件中的所有导入。我有太多的报告文件让我很难想到这样做。

我读了一些关于隐藏导入的内容。也许这可以帮助我，但我不知道。任何帮助，将不胜感激。谢谢。

编辑：py {{2}的similar问题和解决方案....

Answer 1

我不知道我是否这样做是正确的...但是我开始拉头了。

读完并浪费了一大堆时间后，......

我发现有人建议将复制整个丢失的库文件夹（在我的情况下，它是在我的pythonxx的网站包中）放入包含exe的文件夹。瓦拉！它奏效了。

如果有更好/更合适的方法，请赐教。

Answer 2

将名为hook-reportlab.pdfbase._fontdata.py的文件添加到pyinstaller的hooks子目录中。该内容应如下所示：

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']

这对我使用pyinstaller 2.1。顺便说一下，我从pyinstaller 1.5.1借用了这个文件，默认安装它。

PyInstaller生成的exe不工作，项目使用ReportLab
