Question

好吧所以我有一个我要编译的python项目，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时它返回-1。因此，经过一番混乱，我发现它与reportlab.platypus有关。

所以我的第一直觉是检查是否使用了钩子改变了什么，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。

以下是从终端运行exe时的输出：

Traceback (most recent call last):

  File "site-packages\reportlab\lib\utils.py", line 695, in rl_isdir
AttributeError: 'FrozenImporter' object has no attribute '_files'
main returned -1

从此我收集说它在＆＃34; Board_builder.py＆＃34;中运行第5行时崩溃了。（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意味着什么，非常欢迎任何建议！

Answer 1

嗯，我让它运转了，

决定去看看究竟是什么引发了AttributeError所以我检查了reportlab/rl_config.py和reportlab/lib/utils.py文件，发现它正在以递归方式查找目录（正如{{1所暗示的那样） }}）。一些如何使用其他对象列表检查FrozenImporter被卡住了

所以我换了一行：

rl_isdir

使用：

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

这可能不是解决问题的最简洁最有效的方法，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。
