ParserError:错误令牌数据.(TradingWithPython库) - 在一台计算机上工作，而不是另一台计算

Question

我有两台带有jupyter笔记本的python 3的计算机。我在两个上都安装了TradingWithpython库。我正在尝试在每台计算机上运行以下命令：

data = twp.yahooFinance.getHistoricData('SPY')

在一台计算机上它运行完美(这告诉我Yahoofinance库很好(。在另一台计算机上，我会在下面收到错误。有人可以帮我解决这个问题吗？我想念图书馆还是什么？

Answer 1

尝试了所有内容(重新安装Python 3，卸载/重新安装Pandas，TradingWithPython和其他一些库(，无效。但是，我可以在其他计算机上使用它。我决定将新计算机(擦除硬盘驱动器重新安装的操作系统(进行核武器，然后重新开始。解决了这个问题，图书馆现在没有任何问题。我不确定是什么原因导致冲突，但我很高兴它现在正在起作用。

手指越过问题并没有返回，因为我安装其他软件。
