如能帮助解决此问题，我们将不胜感激。

Answer 1

我终于设法解决了这个问题。我发现错误是由于 vyper，因为 vyper --version 也给出了类似的错误。所以，我转到了最后提出的异常：

 File "/home/misterblack/.local/lib/python3.9/site-packages/vyper/old_codegen/parser_utils.py", line 38, in __setattr__
    raise DecimalOverrideException("Overriding decimal precision disabled")

并打开提到的文件..../vyper/old_codegen/parser_utils.py，并注释掉抛出异常的行。 Image of the commented code。如此处所示，这完全消除了错误。我不知道这是否是最好的方法，但它似乎有效。 Success!
