nuitka 无法编译； python解释器工作正常；递归错误

问题描述

所以我有这段代码，它有一些功能。这些函数返回一个长字符串，它基本上是由连接构成的。例如：

def myFunc():

    file = ""
    file = file + "text1\n"
    file = file + "   newText\n"
    [....]
    file = file + "exit\n"

    return file

现在，如果我通过 CLI 调用它就可以了，例如 python3 myProg.py。到目前为止，一切都很好。

但是如果我尝试编译此代码，则会收到此错误：

python3 -m nuitka myProg.py --nofollow-import-to=MysqLdb --nofollow-import-to=time --nofollow-import-to=os --nofollow-import-to=sys --nofollow-import-to=shutil --nofollow-import-to=zipfile --nofollow-import-to=pandas --follow-imports

我所看到的是：如果我缩短串联，我可以毫无问题地编译，这意味着减少 file = file + " blabla" 的数量。

总共，我在 myFunc() 中有 1140 个串联。

我读到使用 sys.setrecursionlimit() 可能会有所帮助。我有它在 3000;将它设置为 8000，但它也没有编译。到目前为止，唯一的解决方案是缩短串联，这是为了测试它是可以的，但不是为了我的代码的正常运行。

关于如何克服这个问题有什么想法吗？

谢谢！
