PyInstaller 生成的 exe 不起作用，项目使用 ReportLab

Question

我正在尝试为我的项目生成一个 exe。大约一个月前，当我的项目没有使用 ReportLab 时，它可以正常工作，但现在情况就不那么好了。

经过搜索，我发现问题是其中一个 pyinstaller 文件缺少导入。问题解决了吗？不完全是。

现在我收到这个错误...

环顾四周，我发现这导致只有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，让我很难考虑这样做。

我读过一些关于隐藏进口的内容。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： py2exe 的类似问题和解决方案......

Answer 1

我不知道这是否是正确的方法......但我开始拔掉我的头发。

在阅读并浪费了大量时间之后，...

我发现有人发表了一篇文章，建议将整个丢失的库文件夹（在我的例子中它位于我的 pythonxx 的站点包中）复制到包含 exe 的文件夹中。瓦拉！有效。

如果有更好/正确的方法来做到这一点，请赐教。
