pyinstaller 和 reportlab 的问题

Question

好吧，我有一个python项目要编译，所以我决定使用pyinstaller（第一次编译python）。现在它编译得很好但是当我运行 exe 时它 returns -1。所以经过一番摸索后，我发现它与 reportlab.platypus.

有关

所以我的第一直觉是检查使用钩子是否改变了什么，所以我尝试添加 reportlab.pdfbase._fontdata 和 reportlab.lib.utils 钩子（这些是我能找到的与 reportlab 相关的唯一钩子文件).尽管如此，它仍然失败了。

这是终端中 exe 为运行时的输出：

AttributeError: 'FrozenImporter' object has no attribute '_files'
main returned -1

据我所知，它在 "Board_builder.py" 中的运行ning 第 5 行崩溃（在我的项目中处理 reportlab 的文件）这里是该文件的前 5 行：

import subprocess
import datetime
from reportlab.lib.units import mm, inch
from reportlab.lib.pagesizes import legal, landscape
from reportlab.platypus import SimpleDocTemplate, Table

我不知道它抛出的 AttributeError 是什么意思，欢迎任何建议！

Answer 1

好吧，我成功了，

决定去看看 AttributeError 究竟是从哪里抛出的，所以我检查了 reportlab/rl_config.py 和 reportlab/lib/utils.py 文件，发现它正在检查对象以递归方式查找目录（如 rl_isdir).一些 FrozenImporter 是如何卡住的，正在检查其他对象列表

所以我替换了行：

return len(list(filter(lambda x,pn=pn: x.startswith(pn),list(__loader__._files.keys()))))>0

与：

try:
    return len(list(filter(lambda x,pn=pn: x.startswith(pn),list(__loader__._files.keys()))))>0
except AttributeError:
    return False

这可能不是解决问题的最干净、最有效的方法，但它只涉及原始代码的一行，所以我发现这是最直接的解决方案。
